For Safety and Performance …ALWAYS READ THIS BOOK FIRSTMcCONNEL LIMITEDTemeside WorksLudlowShropshireEnglandTelephone: 01584 873131www.mcconnel.comNOISE STATEMENTThe equivalent daily personal noise exposure from this machine measured at the operators’ ear iswithin the range 78 – 85 dB, these figures apply to a normal distribution of use where the noisefluctuates between zero and maximum. The figures assume that the machine is fitted to a tractorwith a ‘quiet’ cab with the windows closed in a generally open environment. We recommend thatthe windows are kept closed. With the cab rear window open the equivalent daily personal noiseexposure will increase to a figure within the range 82 – 88 dB. At equivalent daily noise exposurelevels of between 85 – 90 dB ear protection is recommended – it should be used if any window isleft open.

SAFETY SECTIONThis machine has the potential to be extremely dangerous, in the wrong hands it can kill ormaim. It is therefore imperative that both owner, and operator of this machine, read andunderstand the following section to ensure that they are fully aware of the dangers that do,or may exist, and their responsibilities surrounding the use and operation of the machine.The operator of this machine is responsible not only for their own safety but equally for thesafety of others who may come into the close proximity of the machine, as the owner youare responsible for both.When the machine is not in use the cutting head should be lowered to rest on the ground.In the event of a fault being detected with the machine’s operation it should be stoppedimmediately and not used again until the fault has been corrected by a qualified technician.POTENTIAL SIGNIFICANT DANGERS ASSOCIATED WITH THE USE OF THISMACHINE:▲ Being hit by debris thrown by rotating components.▲ Being hit by machine parts ejected through damage during use.▲ Being caught on a rotating power take-off (PTO) shaft.▲ Being caught in other moving parts i.e.: belts, pulleys and cutting heads.▲ Electrocution from Overhead Power Lines (by contact with or ‘flashover’ from).▲ Being hit by cutting heads or machine arms as they move.▲ Becoming trapped between tractor and machine when hitching or unhitching.▲ Tractor overbalancing when machine arm is extended.▲ Injection of high-pressure oil from hydraulic hoses or couplings.▲ Machine overbalancing when freestanding (out of use).▲ Road traffic accidents due to collision or debris on the road.4

BEFORE USING THIS MACHINE YOU MUST:▲ Ensure you read all sections of the operator handbook.▲ Ensure the operator is, or has been, properly trained to use the machine.▲ Ensure the operator has been issued with and reads the operator handbook.▲ Ensure the operator understands and follows the instructions in operator handbook.▲ Ensure the tractor front, rear and side(s) are fitted with metal mesh or polycarbonateguards of suitable size and strength to protect the operator against thrown debris orparts.▲ Ensure tractor guards are fitted correctly, are undamaged and kept properlymaintained.▲ Ensure that all machine guards are in position, are undamaged, and are keptmaintained in accordance with the manufacturer’s recommendations.▲ Ensure flails and their fixings are of a type recommended by the manufacturer, aresecurely attached and that none are missing or damaged.▲ Ensure hydraulic pipes are carefully and correctly routed to avoid damage by chaffing,stretching or pinching and that they are held in place with the correct fittings.▲ Always follow the manufacturer’s instructions for attachment and removal of themachine from the tractor.▲ Check that the machine fittings and couplings are in good condition.▲ Ensure the tractor meets the minimum weight recommendations of the machine’smanufacturer and that ballast is used as necessary.▲ Always inspect the work area thoroughly before starting to note obstacles and removewire, bottles, cans and other debris.▲ Use clear suitably sized warning signs to alert others to the nature of the machineworking within that area. Signs should be placed at both ends of the work site. (It isrecommended that signs used are of a size and type specified by the Department ofTransport and positioned in accordance with their, and the Local Highways Authority,guidelines).▲ Ensure the operator is protected from noise. Ear defenders should be worn and tractorcab doors and windows must be kept closed. Machine controls should be routedthrough proprietary openings in the cab to enable all windows to be shut fully.▲ Always work at a safe speed taking account of the conditions i.e.: terrain, highwayproximity and obstacles around and above the machine. Extra special attention shouldbe applied to Overhead Power Lines. Some of our machines are capable of reach inexcess of 8 metres (26 feet) this means they have the potential to well exceed, bypossibly 3 metres (9’ 9”), the lowest legal minimum height of 5.2 metres from theground for 11,000 and 33,000 volt power lines. It cannot be stressed enough thedangers that surround this capability, it is therefore vital that the operator is fully awareof the maximum height and reach of the machine, and that they are fully conversantwith all aspects regarding the safe minimum distances that apply when working withmachines in close proximity to Power Lines. (Further information on this subject can beobtained from the Health & Safety Executive or your Local Power Company).5

▲ Always disengage the machine, kill the tractor engine, remove and pocket the keybefore dismounting for any reason.▲ Always clear up all debris left at the work area, it may cause hazard to others.▲ Always ensure when you remove your machine from the tractor that it is left in a safeand stable position using the stands and props provided and secured if necessary.WHEN NOT TO USE THIS MACHINE:▲ Never attempt to use this machine if you have not been trained to do so.▲ Never use a machine until you have read and understood the operator handbook, arefamiliar with it, and practiced the controls.▲ Never use a machine that is poorly maintained.▲ Never use a machine if guards are missing or damaged.▲ Never use a machine on which the hydraulic system shows signs of wear or damage.▲ Never fit, or use, a machine on a tractor that does not meet the manufacturer’sminimum specification level.▲ Never use a machine fitted to a tractor that does not have suitable front, rear andside(s) cab guarding made of metal mesh or polycarbonate.▲ Never use the machine if the tractor cab guarding is damaged, deteriorating or badlyfitted.▲ Never turn a machine cutting head to an angle that causes debris to be ejectedtowards the cab.▲ Never start or continue to work a machine if people are nearby or approaching - Stopand wait until they are at a safe distance before continuing. WARNING: Some CuttingHeads may continue to ‘freewheel’ for up to 40 seconds after being stopped.▲ Never attempt to use a machine on materials in excess of its capability.▲ Never use a machine to perform a task it has not been designed to do.▲ Never operate the tractor or machine controls from any position other than from thedriving seat, especially whilst hitching or unhitching the machine.▲ Never carry out maintenance of a machine or a tractor whilst the engine is running –the engine should be switched off, the key removed and pocketed.▲ Never leave a machine unattended in a raised position – it should be lowered to theground in a safe position on a level firm site.▲ Never leave a tractor with the key in or the engine running.▲ Never carry out maintenance on any part or component of a machine that is raisedunless that part or component has been properly substantially braced or supported.▲ Never attempt to detect a hydraulic leak with your hand – use a piece of cardboard.▲ Never allow children near to, or play on, a tractor or machine under any circumstances.6

ADDITIONAL SAFETY ADVICETrainingOperators need to be competent and fully capable of operating this machine in a safe andefficient way prior to attempting to use it in any public place. We advise therefore that theprospective operator make use of relevant training courses available such as those run byAgricultural Training Boards, Agricultural Colleges and Dealers.Working in Public PlacesWhen working in public places such as roadsides, consideration should be paid to othersin the vicinity. Stop the machine immediately when pedestrians, cyclists and horse ridersetc. pass. Restart only when they are at a distance that causes no risk to their safety.Warning SignsIt is advisable that any working area be covered by suitable warning signs and statutory inpublic places. Signs should be highly visible and well placed in order to give clearadvanced warning of the hazard. Contact the Department of Transport or your LocalHighways Authority to obtain detailed information on this subject. The latter should becontacted prior to working on the public highway advising them of the time and location ofthe intended work asking what is required by way of signs and procedure. – ‘Nonauthorisedplacement of road signs may create offences under the Highways Act’.Use of Warning Signs▲ On two-way roads one set of signs is needed facing traffic in each direction.▲ Work should be within 1 mile of the signs.▲ Work only when visibility is good and at times of low risk e.g.: NOT during ‘rush-hour’.▲ Vehicles should have an amber-flashing beacon.▲ Ideally, vehicles should be conspicuously coloured.▲ Debris should be removed from the road and path as soon as practicable, and atregular intervals, wearing high visibility clothing and before removing the hazardwarning signs.▲ Collect all road signs promptly when the job is completed.Although the information given here covers a wide range of safety subjects, it is impossible topredict every eventuality that can occur under differing circumstances whilst operating thismachine. No advice given here can replace ‘good common sense’ and ‘total awareness’ at all times,but will go a long way towards the safe use of your McConnel machine.7

FITTING – Tractor requirementsMinimum Tractor Weight - including ballast weight if necessary:PA50 ECO – 3500kg.PA55 ECO – 3500kg.PA60 ECO – 4000kg.Minimum HP RequirementsAll models – 65HPLinkageCategory 2PTO ShaftTractor must be equipped with a live drive PTO to enable forward motion to be stoppedwhile the flail head continues to operate.Check Chains/Stabilizers:Check chains or stabilizers must be fitted and tightened.8

TRACTOR PREPARATIONFitting Tractor Guard: Use tractor with safetyglass windows if possible and fit Operatorguard (part no. 7313324) using the hooksprovided. Shape mesh to cover all vulnerableareas. Remember the driver must be lookingthrough mesh and/or polycarbonate glazingwhen viewing the flail head in any workingposition - unless the tractor/cab manufacturercan demonstrate that the penetration resistance is equivalent to, or higher than, thatprovided by mesh/polycarbonate glazing. If the tractor has a roll bar only, a frame must bemade to carry both mesh and polycarbonate glazing.Wheel Width: Set wheel widths as wide as possible.Lift Links: Adjust lift links until they are equal length.Tractor Ballast: It is imperative when attaching ‘third-party’ equipment to a tractor that themaximum possible stability of the machine and tractor combination is achieved – this canbe accomplished by the utilization of ‘ballast’ in order to counter-balance the additionalequipment added.Front weights may be required to place 15% of total outfit weight on the front axle forstable transport on the road and to reduce ‘crabbing’ due to the drag of the cutting unitwhen working on the ground.Rear weights may be required to maintain a reasonable amount of rear axle load on theopposite wheel from the arms when in work; for normal off-ground work i.e. hedge cuttingthis should be 20% of rear axle weight or more for adequate control, and for ground worki.e. verge mowing with experienced operators, this can be reduced to 10%.All factors must be addressed in order to match the type and nature of the equipmentadded to the circumstances under which it will be used – in the instance of Power ArmHedgecutters it must be remembered that the machines centre of gravity during work willbe constantly moving and will differ from that during transport mode, therefore balancebecomes critical.Factors that effect stability:• Centre of gravity of the tractor/machine combination.• Geometric conditions, e.g. position of the cutting head and ballast.• Weight, track width and wheelbase of the tractor.• Acceleration, braking, turning and the relative position of the cutting head during these• operations.• Ground conditions, e.g. slope, grip, load capability of the soil/surface.• Rigidity of implement mounting.Suggestions to increase stability:• Increasing rear wheel track; a tractor with a wider wheel track is more stable.• Ballasting the wheel; it is preferable to use external weights but liquid can be added toaround 75% of the tyre volume – water with anti-freeze or the heavier Calcium Chloridealternative can be used.• Addition of weights – care should be taken in selecting the location of the weights to• ensure they are added to a position that offers the greatest advantage.• Front axle locking; a ram can be used to ‘lock’ the front axle in work only – locking the axle• moves the ‘balance line’ and can be used to transfer weight to the front axle from the rear(check with tractor manufacturer).The advice above is offered as a guide for stability only and is not a guide to tractor strength - it istherefore recommended that you consult your tractor manufacturer or local dealer to obtain specificadvise on this subject, additionally advice should be sought from a tyre specialist with regard to tyrepressures and ratings suitable for the type and nature of the machine you intend to fit.9

DELIVERY & PRE-ATTACHMENT (Dealer Reference)DeliveryThe machine will be delivered in a partially dismantled condition secured with transportstraps and banding. Select a firm level site on which to place the machine before removingthe straps, banding and other loose items.Handling the MachineHandling of the machine should always be performed using suitable overhead liftingequipment with a minimum safe lifting capacity over and above the maximum weight of themachine. Always ensure the machine is balanced during the lifting procedure and that allbystanders are kept well clear of the raised machine.Post Delivery AssemblyTo allow for a compact shipping state the machine will be delivered with the tension linkdisconnected from the rocker and the stand legs retracted – these items will need to becorrectly installed before initial attachment to a tractor.The procedure is as follows:Stand LegsRaise the machine using suitableoverhead lifting equipment.Lower stand legs and secure inposition using pins and locking pins –the hole position selected should beat a height that places the gearboxstub axle approximately 75mm (3”)below the height of the tractor’s PTOshaft when the machine is at rest onthe ground. Note the hole positionused and ensure the equivalent oneis used on both sides of the machine10

HYDRAULIC OILHydraulic Oil ReservoirFill the tank with oil selected from the chartbelow or a good quality equivalent to a pointwhere the level is between the minimum andmaximum marks on the tank gauge. Whenthe machine is initially run the level will dropas the oil is drawn into the circuit - top backup as required to the correct level on thegauge.Always use clean receptacles when handlingand transferring oil to avoid moisture or dirtcontamination that can damage componentsand/or reduce machine performance.NOTE: Refer to the maintenance section for further information on the subject of hydraulicoil and system filtration.Reservoir CapacityThe oil tank capacity of the machine is approximately 200 Litres.Recommended Hydraulic OilsFor initial filling of the oil reservoir, periodic oil changes and replenishment purposes thefollowing hydraulic oils, or a good quality equivalent are recommended:NOTE: Only use oils that are ISO 18/13 or cleaner.Manufacturer Cold or Temperate Climate Hot ClimateBP Bartran 46Energol HLP-HM 46Bartran 68Energol HLP-HM 68CASTROL Hyspin AWH-M 46 Hyspin AWH-M 68COMMA Hydraulic Oil LIC 15 Hydraulic Oil LIC 20ELF Hydrelf HV 46Hydrelf HV 68Hydrelf XV 46ESSO Univis N 46 Univis N 68FUCHS(UK/Non UK markets*)Renolin 46Renolin HVZ 46Renolin CL46/B15*Renolin AF46/ZAF46B*Renolin 68Renolin HVZ 68Renolin CL68/B20*Renolin AF68/ZAF68B*GREENWAY Excelpower HY 68 Excelpower HY 68MILLERS Millmax 46Millmax HV 46MORRIS Liquimatic 5Liquimatic HV 46Triad 46SHELL Tellus 46Tellus T46TEXACO Rando HD 46Rando HDZ 46Millmax 68Millmax HV 68Liquimatic 6Liquimatic HV 68Triad 68Tellus 68Tellus T68Rando HD 68Rando HDZ 68TOTAL Equivis ZS 46 Equivis ZS 6811

ATTACHMENT TO TRACTORPosition the tractor squarely to the machineplacing the draft links at the same height asthe mainframe attachment points.Carefully reverse the tractor up to themachine until the draft links are positionedfor attachment – select the rear most holeon the machines lower link brackets thatallows the machine to be mounted withoutfouling the tractor.Attach the tractor draft links to the machineusing pins provided and secure in position -ensure the same mounting hole is selectedon each side of the machine.If necessary fit the spacers supplied tominimise sideways movement of the draftlinks within the hitch bracket12

Fit the stabilizer into position with its armsaligned with the holes of the main frameand attach the stabilizer nose to the tractorstop link – select the highest possibleposition available avoiding any loadsensing properties.NOTE: The bolt on nose of the stabiliser isreversible in order to accommodatevariations of tractor linkage designs.McConnel offer various versions ofstabilizer noses for differing types andmakes of tractors – contact your localdealer or McConnel Parts Department forfurther information.Secure the stabiliser in position using thefixings provided. Attach the stabiliser arm tothe machine selecting the lowest holepossible.Fit top link between the stabiliser and themainframes upper linkage point.13

Secure top link in position using fixingsprovided.Raise the machine on the tractors linkage toa height where the tractors PTO and thestub axle of the machines gearbox areapproximately in line with each other.Note: As lift occurs be aware the machinemay tilt slightly.WARNING!The quadrant lever or machine controlsmust only be operated from the tractorseat. Ensure no one is standing on,between, or near the linkage arms orbars during this procedure.Adjust the top link to bring the machineframe into the vertical position.14

Remove leg pins and raise the stand legs totheir stowage position – replace leg pinsand secure in place with ‘R’ clips.Adjust check chains to prevent sidewaysmovement of the tractor’s linkage.Measure the PTO shaft and cut to thedimension shown below. The finished lengthof the shaft should be 75mm (3”) less thanthe measured distance ‘A’ between tractorshaft and gearbox stub shaft to allow forfitting. Refer to PTO installation page.NOTE: For subsequent use with differenttractors, measure again - there must be aminimum shaft overlap of 150mm (6”).When the PTO shaft is in position attachtorque chains to convenient locations toprevent rotation of the shaft guarding.Fit the machine control unit in the tractor cab in a convenient location that allows for safeand easy operation of all the controls and functions.15

PTO DRIVESHAFT INSTALLATIONThe PTO driveshaft attaches between the tractor and the machine gearbox to transfer thepower required to the run and operate the machine – it is important to achieve the correctshaft length to avoid risk of it ‘bottoming out’ when raising or lowering the machine.The procedure for measuring andcutting the shaft is as follows:Measuring the PTO ShaftWith the machine attached to thetractor in the working position measurethe horizontal distance ‘A’ from thetractor’s PTO to the input shaft on themachines gearbox and subtract 75mm(3”) – this figure is the required shaftlength.Place the fully closed PTO shaft onthe ground and measure its overalllength, if the shaft is shorter than therequired length you can use it withoutthe need to shorten - providing itallows for a minimum 150mm (6”)overlap when fitted.If the shaft is longer subtract therequired shaft length plus an additional75mm (3”) - the resulting figure is theexcess length that will need to beremoved from each half of the shaft.Cutting the PTO ShaftSeparate the two halves and using themeasurement obtained above shortenboth the plastic guarding and the innersteel profile tubes of each shaft by thissame amount. De-burr the cut tubeswith a file to remove rough or sharpedges and thoroughly clean to removeswarf before greasing, assembling andfitting the shaft.NOTE: For subsequent use with different tractors the shaft should be measured again tocheck suitability – there must be a minimum shaft overlap of 150mm (6”).MaintenanceTo increase the working life of the PTO shaft it should be periodically checked, cleanedand lubricated – refer to the PTO maintenance section for further details on this subject.16

FITTING OPERATOR CONTROL UNITSFitment of the operator controls in the tractor cab will vary depending on the particularmodel or specification of machine – the information below lists the differing methods offitment for the various types of controls available.NOTE: Electric control units work within the range of 12v-16v DC and will require aminimum power supply of 12v DC.Cable ControlsCable control units are provided with, and attached to, a mounting bracket – the bracketshould be securely fixed to the internal mud wing or cab cladding in a suitable convenientlocation that offers ease of use without interfering with normal tractor operation.In deciding the final position of the control unit bear in mind the location of the cable run –make sure the minimum acceptable cable bend radii of 8” (200mm) is not exceeded.Ensure during fitting that no structural member of the tractor cab or roll bar is drilled ordamaged.The cable rotor control valve lever on cable controlled machines will be assembled as acomponent part of the main bank of controls and therefore shares the same mountingbracket.On electric machines with cable operated rotor control valve the lever will be supplied as a‘standalone’ unit with its own individual mounting bracket – this should be fitted in thesame manner as above adopting the same precautions pertaining to attachment and cableruns.Electric ControlsDepending on the particular type of control, electric units are supplied either with amounting bracket or a mounting pillar which should be bolted to the internal mud wing orcab cladding in a suitable convenient location that offers ease of use without interferingwith normal tractor operation. Mounting pillars can be bent or twisted to achieve acomfortable working position. Ensure during fitting that no structural member of the tractorcab or roll bar is drilled or damaged.The power supply cable should be connected directly to the tractors battery - do not usecigarette lighter type connections as these prove to be sporadic and unreliable for controlapplications. Control units are 12 volt DC operated; the brown lead is positive (+) and theblue lead is negative (-).Proportional Armrest ControlsV4 proportional controls comprise of 2 units; the main control box and the armrest controlunit. The control box is supplied with a mounting bracket and suction cup assembly thatallows the unit to be mounted on the window of the tractor cab – ensure the surface usedis clean and dry and that the unit is mounted in a position where it does not obstructoperator vision. The armrest control is designed to slide over the armrest of the tractorseat and is held in place with the fixing straps provided.The power supply cable should be connected directly to the tractors battery - do not usecigarette lighter type connections as these prove to be sporadic and unreliable for controlapplications. Control units are 12 volt DC operated; the red lead is positive (+) and theblack lead is negative (-).17

FLAILHEAD ATTACHMENTFor ease of attachment and safety this procedure is best performed on a firm level site.With the tractor parked alongside the flailhead operate the controls of the machine toposition the pivot bracket of the machines head angling mechanism directly behindflailhead with the base of the hose tray (or junction bracket) parallel to the ground.Manoeuvre the flailhead backwards on its roller until the heads attachment bracket isadjacent to the machines pivot bracket. Fit the 4 attachment bolts through the bracketsfrom the arm side - if the holes are mis-aligned carefully operate the angling ram until theholes correspond.WARNING: Ensure all persons remain at a safe distance whilst operating the anglingfunction as the geometry of the head angling mechanism produces several pinch risk areas.With the attachment bolts correctly located through the brackets fit the self-locking nutsand tighten alternately until the brackets are drawn flush before finally tightening them to atorque setting of 203Nm (150ft.lbs).Flailhead Hose AttachmentWith the flailhead attached to themachine the hydraulic hoses cannow be connected – refer todiagrams opposite. Upper port ‘A’on the motor connects to junctionbracket point ‘A’ on the arm andlower port ‘B’ on the motorconnects to junction bracket point‘B’ on the arm.Note: If a hose tray is alreadyfitted to the arm it will need to beremoved to allow the hoses tobe connected to the junctionbracket – ensure the hose tray isreplaced once the hoses havebeen connected.18

RUNNING UP PROCEDURECAUTION! Before initial use of a new machine, all lubrication points must begreased and the gearbox and oil tank levels checked and where required toppedup before attempting to use the machine. See maintenance section for details.‘Running Up’ the MachineEnsure that the rotor control valve is in "STOP" position.Start tractor, engage PTO and allow the oil to circulate through the return l ine filter forabout 5 minutes without operation of the armhead control lever.Operate the armhead levers through their complete range ensuring that all movements arefunctioning correctly.Place the flail head at a safe attitude and move the rotor control to "START" position; afterinitial fluctuation the rotor should settle to a steady speed.Increase PTO speed to approximately 360RPM and run for a further fi ve minutes beforedisengaging and stopping tractor.Check the hose runs and observ e that they are free from any pinching, chaffing, strainingor kinks.Re-check the oil level in the tank-and top up as necessary.EMERGENCY STOPPINGIn all emergency situations machine operation and functions must be stopped immediately;Stop PTO operation using the tractor controls then immediately kill electrical power to themachine using the Off (Emergency Stop) switch on the machine’s control unit.WARNING: Auto-Reset MachinesWhen the Auto-Reset feature is active the machines arm set is capable ofunintentional movement even when the PT O is switched off and stationary.Always ensure that electrical power to the machine is switched off using th eOff (Emergency Stop) switch on the machine’s control unit in emergencysituations and/or when the machine is not being operated.WARNING: Cable Operated MachinesIn certain conditions, and/or if the Auto -Reset feature is active, the arm setson cable operated machines possess the potential to move unintentionally ,even when the PTO is switched off and st ationary, if the levers were to beaccidentally operated. Care must be adopt ed to avoid any movement of thelevers when the machine is not being operated. Ensure arm sets are loweredfully to the ground when the machine is parked up or not in use.19

PRE-WORK PREPARATION & PRECAUTIONSIMPORTANT: Always read the book first before attempting to operate the machine –practise operating the machine, without the rotor running, in a safe open space until youare fully familiar with all controls and functions of the machine. Only begin using themachine for work when you are confident that you have mastered the controls andoperation sufficient for safe use of the machine.CAUTION: Care must always be taken when working with the flailhead close in toavoid contact with the tractor.Pre-work Machine ChecksPrior to use of the machine always check all bolts are tight and that the torque figures arecorrect for the specific locations indicated below:52 NmMotor BoltsRoller End Capscrews203 NmRotor BoltsFlail BoltsRoller Bracket BoltsGeneral Work PrecautionsInspect the work area prior to operation, remove any hazardous materials and note anyimmovable objects - it may also be a wise precaution to mark immovable hidden hazardswith a visible marker that can easily be seen from the operating position in the tractor.If the type of work being undertaken makes this important precaution impractical, alwaysmaintain a high degree of alertness and restrict the tractors forward motion to a speed thatallows sufficient time to stop the tractor or avoid the hazard before contact is made.General Working PracticeIt is the operator’s responsibility to develop safe working procedures;Always:▲ Be aware of potential hazards in the vicinity of the work area.▲ Ensure all guards are fitted correctly and in good condition.▲ Disengage PTO before stopping the engine.▲ Wait until the flail has stopped running before leaving the tractor seat.▲ Disengage the PTO, stop the engine, remove and pocket the key before making anyadjustments to the machine.▲ Check frequently that all nuts and bolts are tight.▲ Keep bystanders at a safe distance.20

REMOVAL FROM TRACTORDANGER!READ CAREFULLY BEFORE COMMENCING TO REMOVE THE MACHINE FROMTHE TRACTOR.THE ORDER OF THE FOLLOWING STEPS MUST BE FOLLOWED EXACTLYDISCONNECTING THE TOP LINK MUST BE THE LAST OPERATION PRIOR TODRIVING THE TRACTOR AWAY FROM THE MACHINE.WARNING!Do not operate quadrant lever or machine controls through the rear cab window whilststanding on or amongst linkage components. Always seek assistance.Select a firm level site for parking the machine.Replace parking legs in their sockets and secure in their lowest position.Raise the machine on the tractor linkage until the weight is taken off the stabiliser.Remove the lower stabiliser pins.Unscrew the lift ram tap.Lower the machine to be ground.Extend the arms and place the flail head on the ground at half reach.Disengage tractor PTO and remove.Disconnect stabiliser bars and/or loosen check chains as applicable.Remove control unit from tractor cab and stow in a safe location clear of the ground.Disconnect the stabiliser from the tractors top hitch position.Remove draft link pins and carefully drive tractor clear of the machine.STORAGEIf machine is to be left standing for an extended period of time, lightly coat the exposedportions of the ram rods with grease. Subsequently, this grease should be wiped off beforethe rams are next moved.If the machine has to be stored outside tie a piece of tarpaulin or canvas over the controlassembly, do not use a plastic fertilizer bag which could lead to rapid corrosion.21

OPERATIONOperator GuardMachine GuardsBefore each period of work, check that all the relevant tractor and machine guards are inplace and in good working condition.Small splits and abrasions on the lower edges of the flail head rubber flaps arepermissible, but should one or more of these cuts or splits become fifty per cent or more ofthe flap height they should be replaced immediately as they will have become ineffectivefor debris containment.Operator SafetyDuring operation all the tractor windows should be kept firmly closed with the exception ofthe rear window which may be opened only to the extent that is sufficient to allow entry ofelectrical or operating cables for the machine into the cab.Should the tractor not be fitted with a 'quiet' cab ear defenders must be worn at all times,failure to heed this warning may result in permanent damage to hearing.Although in normal circumstances a working machine or rotating parts should never beapproached it is an additional wise precaution to avoid wearing loose or flapping clothesespecially scarves and neckties whilst in close proximity to a machine.The operator should continually guard himself and others from complacency that can arisefrom familiarity. Never attempt to take 'short cuts', always follow the correct proceduresdiligently and abide by the restrictions imposed by safety considerations.REMEMBER: there is only one right way - the safe way!22

CABLE CONTROLSCable controlled machines are supplied with a control unit of the type shown below – theparticular version will be depend ent on the specific ation and features of the machine.Versions differ primarily in the number of armhead c ontrol levers assembled within t hecontrol bank – some versions will have the rotor control lever assembled alongs ide thearmhead control levers as shown below left and others will be supplied with the r otorcontrol lever as a ‘standalone’ unit with its own individual mounting bracket.The armhead control levers all move in a forwards and backwards direction eac hcontrolling a specific arm function with the exception of the auto reset lever which operatesonly in the backward direction (from central ‘off’ position to the backwards ‘on’ position).Where applicable, if a machine is fitted with the optional lift fl oat feature, operation of thelift float will be v ia an additional electrical switch which will n eed to be installed in aconvenient location in the tractor cab.Basic Cable Control UnitCable Control Unit with Auto ResetLOCATION & FUNCTION OF CONTROLS1.

CABLE ROTOR CONTROLOn cable rotor control machines the rotor is operated by the lever shown below – from theupright ‘off’ position pushing the lever forward switches the rotor on for downhill cutting andpulling the lever backwards switches the rotor on for uphill cutting. The small pivot lockinglever mounted on the side of the control assembly rotates through 180° to lock the rotor ina specific cutting direction – this is a safety feature to avoid changes of rotor directionwithout first stopping the rotor. To change the direction of cut the rotor lever must beplaced in the upright ‘off’ position; when the rotor has stopped rotating completely the pivotlocking lever can be turned to the opposing position allowing the control lever to beoperated for opposite cutting direction.On some cable operated machines the rotor control lever will be assembled as part of themain bank of controls, whereas on others and all electric models it will be supplied as a‘standalone’ unit with its own mounting bracket.UPHILL CUTTINGLockDOWNHILL CUTTINGLockCAUTION: Ensure the rotor has stopped turning completely before attempting to changedirection - When switched off a rotor can continue to ‘freewheel’ under its own momentumfor up to 40 seconds before stopping.26

Switching Rotor DirectionWith the rotor running, changing the rotor cutting direction can only be achieved after firstoperating ‘rotor stop’, when stop has been selected the specific direction button can thenbe operated to command the rotor to switch to the desired direction. NOTE: This functionhas a built in time delay of approximately 8 seconds - this is a machine protection featurethat allows the rotor sufficient time to de-accelerate before restarting in the oppositedirection. The LED light of the active cutting direction will flash on and off during theslowing down period, when the direction has changed the LED for the new direction will beilluminated.Switching the Rotor OffStopping the rotor is performed by operation of the rotor stop button as illustrated below.When rotor off has been selected the LED light above the button of the active cuttingdirection will flash on and off for approximately 8 seconds to signify that the rotor has beenswitched off, after this 8 second period the light will go off completely. NOTE: The rotor willcontinue to rotate under its own power until it finally comes to a standstill.CAUTION: When the rotor is switched off it will continue to ‘freewheel’ under its ownmomentum for up to 40 seconds before finally coming to a standstill – do not leave thetractor cab or attempt to approach the flailhead until the rotor has stopped turningcompletely.38

Scrolling forward [►] again displays the Power Monitorscreen.Scrolling backwards [◄] will display the screens in theopposite order.49

POWER MONITORWhen displayed the power screen will indicate to the operator the level of power beingdemanded by the cutting head – an ascending graphic indicates the power demand statusfrom minimum on the left of the screen to maximum on the right.Power Status – Low DemandPower Status – High DemandWhen the power demand approaches the maximum limit an audible warning will alert theoperator to indicate that the rotor is under excess load and at risk of ‘stalling’ – when thisaudible warning sounds the operator should reduce the forward tractor speed to protectthe machine and regain efficient cutting power – the audible warning will cease when thepower demand returns to an acceptable level.In certain cases, cutting materials of extreme density may cause an increase in the powerusage to the ‘warning level’ – in these types of conditions raising the cutting head into aless dense area of the material will regain an acceptable power demand. It is advisablethat work in problematic high density materials be performed in several passes, loweringthe cutting head slightly on each pass until the required cut height is achieved.ADDITIONAL CONTROL & SCREEN SETTINGSAdditional settings available to the operator can be found within the settings menu of thecontrol unit and accessible via the screen and menu buttons on the control panel.Access is gained by simultaneously pressing the scroll [◄] [►] buttons on the controlpanel until the unit emits a ‘beep’ and the setup screen appears on the LCD - the featurescan then be ‘scrolled’ to (forwards or backwards) by subsequent operation of either of thescroll [◄] [►]buttons. When the required screen is reached the tick [] button should bepressed to enter the settings menu for that feature.THUMB (Thumbwheel Switching) – this allows the operator to ‘swap over’ the left andright thumbwheel functions so that they control the opposing features. In most cases thissetting will be dictated by the operators’ personal preference and once chosen theoperator will keep it in the selected mode.Options are ‘Normal’ or ‘Swap’ – selection is by ‘highlighting’ the required option usingeither of the scroll [◄] [►] buttons – the feature is then activated using the tick [] button.Pressing the [X] button exits the screen settings and returns to the normal work screen.LED (Screen Contrast) - this setting allows the operator to adjust the contrast level of theLED display – the feature affords the option to increase or decrease the contrast level tosuit differing lighting conditions; this is particularly useful on dull or sunny days wherereduced or increased natural light can affect screen clarity.Options are ‘Increase Contrast’ or ‘Decrease Contrast’ – selection is by ‘highlighting’ therequired option using either of the scroll [◄] [►] buttons – once selected that particularoption can then be adjusted in incremental steps by pressing the tick [] button therequired number of times to achieve the desired contrast. Pressing the [X] button exits thescreen settings and returns to the normal work screen.CAUTION: Avoid adjusting the contrast level to a state where the screen cannot be viewed as exitingthe settings menu in this condition may render the LCD unusable as the ‘on screen’ prompts may nolonger be visible to the user.NOTE: Some screen menus are inaccessible to the operator – these are for factory or dealer use onlyand are password protected to avoid inadvertent changes to specific control settings.50

TEST & FAULT FINDING SCREENSThe following screens are available for testing and fault finding purposes, these are:JOYSTICK TEST SCREENThis screen reports the status of the CAN (ControllerArea Network) signal from the joystick during its variousfunctions.X and Y DisplayThese report the joystick signal as it travels through its range of movements in its 2 axis –the ‘X’ axis being the ‘Lift’ up and down function and the ‘Y’ axis the ‘Reach’ in and outfunction.With the joystick in the central (neutral) position both ‘X’ and ‘Y’ on the screen should read0 (zero). When the joystick is moved through a specific axis the relevant readout willincrease or decrease depending on the direction and distance of movement up to amaximum of +1000 in the fully forward or fully right position and -1000 in the fully back orfully left position. If the display reports a reading above the + or – 1000 figure at any pointof full travel the joystick has developed a fault and should be repaired or replaced.R1 and R2 DisplayThese report the signals from the 2 thumbwheels on the top of the joystick and arecalibrated to read +1000 in the fully back position and -1000 in the fully forward position. Ifeither of the ‘R’ readings are above the + or – 1000 figure at the point of full travel thethumbwheel has developed a fault and should be repaired or replaced.B1 and B2 DisplayThese report the status of the 2 joystick buttons and will display ‘ON’ when the button isactivated or ‘OFF’ when deactivated. The readings below B1 and B2 on the screen recordusage of the buttons.EDS STATUS SCREENAlthough this screen is present on all v4 controls, with theexception of the voltage reading, the information it reportsis only actually relevant to machines fitted with EDS.In addition to the aforementioned voltage reading thescreen will report Lift Ram Pressure and Reach Positionstatus – in each case these will display ‘OK’ when thesystem is working correctly. If ‘FAULT’ is displayed next toone or other feature it means a problem has beendetected with that component and it should beinvestigated further to locate and correct the problem.NOTE: As the pressure and position features are not present on Non EDS machines by default thescreen will display ‘FAULT’ next to the features on these models – this is normal and should beignored. The voltage reading will be relevant on all models.REACH FUNCTION SCREENThis screen displays the status of the joystick reach function and indicates to the operatorif the controls are set for correct operation of the machine to the left hand side of thetractor or to the right hand side of the tractor. The hand symbol with a displayed on itindicates the operating side that is currently active.L/H Machine Operation51R/H Machine Operation

SLEW & LIFT LOCKSSlew Ram LockThe machine is fitted with a slew ram lock asshown opposite. The slew function must be‘locked’ at all times during transportation andstorage of the machine and only unlocked forwork.SLEW RAM LOCK ►Open – only for workingClosed – always for transport & storageLift Ram LockTthe machine is fitted with two lift ram locktaps - these taps should always be closedduring transport and storage of the machineto prevent any movement of the arms duringtransportation or when the machine is parkedup. The tap lock(s) will be similar to the oneillustrated opposite.CAUTION!▲LIFT RAM LOCK TAPOpen – only for workingClosed – always for transport & storageSlew and Lift Locks must be in the closed / locked position at all times duringmachine transportation and storage – open / unlock only for work.52

BREAKAWAYThe machine is fitted with a hydraulic breakaway device which protects the structure of themachine should an unforeseen obstacle be encountered.NOTEThe breakaway function does not relieve the operator of his responsibility to drivecarefully, be alert and AVOID OBVIOUS HAZARDS BEFORE CONTACT OCCURS.Breakaway may occur momentarily during normal work should an extra thick or densepatch of vegetation be encountered. In these instances tractor forward motion may bemaintained with care.Where breakaway has occurred as a result of contacting a post or tree etc. the tractormust be halted and the controls of the machine utilised to manoeuvre the head away fromthe obstacle. NEVER CONTINUE FORWARD MOTION TO DRAG THE HEAD AROUNDTHE OBSTACLE IN BREAKBACK POSITION.NOTEThe force required to activate the breakaway system will vary dependent upon thegradient of work. It will require less force when working uphill and vice versa.On mid-cut machines the geometry of the breakaway will cause the head to initially moveoutwards in addition to rearwards. Therefore be aware that the breakaway action will beimpeded if the outer end of the head is working against a steep bank. In this circumstanceextra care must be taken during operation to avoid this occurrence.Breakaway occurs at the slew column pivot. When an obstacle is encountered continuedforward motion causes the pressure in the slew ram base to rise until the relief valvesetting is exceeded.With 'Auto Reset' selected:When the slew relief valve setting is exceeded oil isdisplaced from the slew ram into the base of the liftram which causes the head to rise as the arm pivotsbackwards to clear the obstruction.Resetting of the head into the work position occursautomatically.With 'Slew' selected:When the slew relief valve setting is exceeded oil isdisplaced from the slew ram allowing the arm topivot backwards horizontally and the obstacle to becleared.Re-setting the head into the work position is carriedout manually by selecting 'SLEW OUT' on thecontrol assembly53

POWERED SLEWThe slew feature allows a 95° arc of powered arm movement on the working side fromright angles to the tractor to 5° beyond the direct line astern.The feature is required to place the machine in the transport position but can also be usedto sweep the arm to and fro whilst cutting awkward areas and corners thus avoiding theneed to constantly re-position the tractor. To operate in this way 'SLEW' must be selectedon the control assembly.If breakaway occurs the slew motion must be reversed to allow the slew breakawayrelief valve to re seat and the ram to become operable again.CAUTIONExtra care must be taken when working in 'SLEW’ mode with the reach fully in –IT IS POSSIBLE FOR THE FLAILHEAD TO HIT THE TRACTOR OR MACHINE FRAME.WIRE TRAPThe flail head is equipped with a wire cutting edge welded into the underside. This is toensure that the ends of any wire that may be entwined in the rotor are cut and fall withinthe confines of the flail head. This plate should not be interfered with in any way.Any wire caught in the rotor must be immediately removed (see below).Removing WireSelect rotor 'OFF' and wait until it has stopped rotating.STOP the tractor and only then remove wire.Do not reverse the rotor in an attempt to unwind any wire.54

MOVING INTO TRANSPORT POSITIONSelect ‘Rotor Off’ and wait for the rotor to stopturning completely.Ensure that both ‘lift’ and ‘angle float’ functionsare switched off.Select ‘slew’ mode on the controls.Operate ‘slew in’ function to bring the arms intoposition directly behind the tractor.Operate ‘lift’ and ‘reach’ to position the asshown in the diagram opposite.Place transport prop into the transport positionWork PositionTransport PositionOperate ‘reach in’ until the dipper arm contacts thetransport prop.Select ‘lift up’ and raise the arms until the tension link is300mm (12”) from the tractor cab.Operate ‘angle’ to move the flailhead into a position whereit is as compact as possible.Close lift ram tap(s).Close slew ram tap.Disengage the PTO shaftEnsure power to the control unit is switched off.See following page for additional information regarding transport positions.55

TRANSPORT POSITION FOR REAR MOUNTED MACHINESThe machine is transported inline to the rear of the tractor with a minimum of 300mm (12”)clearance between the tension link and the rear cross member of the tractor cab.Transport Position with Flailhead AttachedTransport Position with Flailhead RemovedFor transportation without a flailhead attached, the machines arms must be fully folded andthe lift ram fully retracted so the mass of the arms is behind the centre line – If the lift ramwas extended the weight of the arms would be in front of the centre line which would resultin the balance of the machine going ‘over centre’ causing the tension link to crash into therear cross member of the tractor’s cab.WARNING: During transport the 'SLEW’ mode must ALWAYS be selected on the controls.56

TRANSPORTING THE MACHINETransport HeightThere is no fixed dimension for the transportheight as this will vary for differing applicationsi.e. tractor size, carrying height, and degree ofarm fold the particular tractor cab will permit.For the majority of installations the transportheight will be in the region of approximately3.45m to 3.65m.It is advisable that once your machine hasbeen installed on the tractor that it is foldedinto the transport position and your ownmeasurement taken to ensure you have anaccurate figure for the transport height.3.45mto3.65mCAUTION: Always be aware of the transport heightof your machine and proceed with care whenmanoeuvring near building, bridges and all otheroverhead obstructions.Approximate transport heightTransport SpeedThe acceptable speed of transport will vary greatly depending upon the ground conditions.In any conditions avoid driving at a speed which causes exaggerated bouncing as this willput unnecessary strain on the tractors top hitch position and increase the likelihood of thetension link coming into contact with the cab rear cross member.WARNING: During transportation of the machine the PTO must be disengaged and power to thecontrols switched off.MOVING FROM TRANSPORT TO WORKReverting to the work position is basically a reversal of the previous work to transportprocedure.NOTE: Always remember to release the slew ram and lift ram locks before attempting to move themachine from the transport position.Engaging DriveEnsure that the rotor control lever is in the 'Stop’ position before engaging the PTO shaft.Allow the oil to circulate for a minute or so before operating the armhead levers. Positionthe flail head in a safe position, increase the engine speed to a high idle and move rotorcontrol lever to 'Start’. After initial surging the rotor will run at an even speed.57

OPERATING SPEEDSPTO Operating SpeedThe correct PTO speeds for operation of machines is: 500 - 540 rpm (Max)WARNING: Damage to the machine may occur if the maximum PTO speed is exceeded.Engaging DriveEnsure the rotor control lever/switch is in the ‘stop’ position before engaging the PTO.Allow the oil to circulate for a minute or so before operating the armhead controls.Move the flail head into a safe working position just clear of the material to be cut.Increase engine speed to a high idle and start the rotor – after initial ‘surging’ the rotor willrun at an even speed.Carefully lower the flail head into the work area and begin work.Tractor Forward SpeedThe material being cut will determine the tractorforward speed. Forward speed can be as fast asthat which allows the flail head sufficient time to cutthe vegetation both efficiently and neatly.If forward speed is too fast this be indicated byover frequent operation of the breakaway system,a fall off in tractor revs and a poor untidy finish tothe work leaving ragged uncut tufts and poorlymulched cuttings.‘Running In’ a New MachineFor the first days work with a new machine it isrecommended that tractor forward speed isrestricted to 3 km/hr (2 mph) maximum. This willallow machine components ‘bed in’ and allow theoperator to become familiar with the controls andtheir response under working conditions whilstoperating at a relatively slow speed. If possible,select a first days work that affords mainly light toaverage cutting with occasional heavy duty work –during this period check the tightness of nuts andbolts every hour, retightening as and whenrequired.58

HAZARDS & DANGERSAdverse SlopesWhen working with the flailhead high and reachfully in it is possible for the main arm balance togo over centre and take the weight off the liftram. A restrictor in the gland circuit of the lift ramwill prevent sudden unpredictable movements ifthis should occur - for reasons of safety thisrestrictor should not be removed.DANGER!NEVER REMOVE THE RESTRICTORFROM THE LIFT RAM GLAND CIRCUIT.Never work the machine on adverse slopes with thearms positioned such that the tractor is unbalanced ►DANGER!NEVER CUT TO THE BLIND SIDE OF A HEDGE- it is impossible to see any potential hazards ordangers and the position of the flail head would allowdebris to be propelled through the hedge towards thetractor and operator.DANGER!NEVER OPERATE THE MACHINE WITHTHE FLAIL HEAD ROLLER REMOVEDDANGER!WHEN GRASS MOWING THE ROTOR MUST ALWAYSCUT IN THE UPHILL DIRECTION WITH FRONT HOODFITTED AND THE ROLLER POSITIONED BELOW THECUTTING HEIGHT OF THE FLAILS59

OVERHEAD POWER LINES (OHPLs)It cannot be stressed enough the dangers involved when working in the vicinity ofOverhead Power Lines (OHPLs). Some of our machines are capable of reach in excess of8 metres (26’); they have the potential to well exceed, by possibly 3 metres (9’ 9”), thelowest legal minimum height of 5.2 metres from the ground for 11,000 and 33,000 voltpower lines.Remember electrocution can occur without actually coming into contact with a power lineas electricity can ‘flashover’ when machinery gets close to it.WARNING: All operators must read the following information and be awareof the risks and dangers involved when working in the vicinity ofOverhead Power Lines (OHPLs).Wherever possible the safest option is always to avoid working in areas close to OHPLs.Where unavoidable, all operators must perform a risk assessment and implement a safeprocedure and system of work – see following page for details.All operators should perform a risk assessment before operating the machine within 10mhorizontal distance of any OHPLs.Minimum Heights for Overhead Power LinesAbsolute Minimum Exclusion Zones for Specific Overhead Power Lines60

Definitions of Exclusion ZonesRisk AssessmentBefore starting to work near OHPLs you should always assess the risks. The followingpoints should be observed;Know the risks of contacting OHPLs and the risk of flashover.• Find out the maximum height and maximum vertical reach of your machine.Find out the location and route of all Power Lines within the work area.Find out the operating voltage of all Power Lines within the work area.Contact the local Distribution Network Operator (DNO) who will be able to advise youon the operating voltage, safe minimum clearance distance for working, and additionalprecautions required.Never attempt to operate the machine in exclusion zones.Always work with extreme caution and plan your work ahead to avoid high risk areas.If doubt exists do not work in the area – never risk the safety of yourself or others.Emergency Action for Accidents Involving Electricity Never touch an overhead line - even if it has been brought down by machinery, or hasfallen. Never assume lines are dead. When a machine is in contact with an overhead line, electrocution is possible if anyonetouches both the machine and the ground. Stay in the machine and lower any raisedparts in contact or drive the machine out of the lines if you can. If you need to get out to summon help or because of fire, jump out as far as you canwithout touching any wires or the machine - keep upright and away. Get the electricity company to disconnect the supply. Even if the line appears dead, donot touch it - automatic switching may reconnect the power.Further information and leaflets on this and other agricultural safety subjects are available on the‘Health & Safety Executive’ website at the following address: www.hse.gov.uk/pubns/agindex.htm61

HEDGECUTTING PROCEDURECut the side and bottom of the field side first.This leaves the maximum thickness of hedgeon the road side to prevent the possibility ofany debris being thrown through the hedgeinto the path of oncoming vehicles.Cut the side and bottom of the road side.Top cut the hedge to the height required.62

LIFT FLOAT (Optional Extra for Ground Work)Work without lift float requires far more concentration and input from the operator toquickly react and re-adjust to the ground contours often resulting in patches of higher cutmaterial where the head is cutting too high and ‘scalping’ of the ground where it is cuttingtoo low – in the case of the latter this can lead to increased flail wear, damage or even lossof flails.The Lift float feature is an optional extra for use during mowing work. When the function isactivated the pressurised accumulator(s) work in conjunction with the valve and lift ram totake a proportion of the flailheads weight off the flail roller allowing the head toautomatically follow the natural contours of the ground; this produces a cleaner moreuniform cut without the need for constant operator re-adjustment. On EDS models thefunction has 3 user settings for differing working conditions – these are soft, medium andhard. Refer to the relevant control section for details of selecting the required setting.Operation of the lift float function is as follows: with lift float switched off, position theflailhead approximately 1m clear of the ground before switching the float function on tocharge the accumulator(s) – the arms may drop at this point depending on the currentlevel of retained pressure. Lower the flailhead into the work position, release the lift controland proceed to work. NOTE: with the exception of EDS models, occasional operation ofthe lift function will be required when working on downhill or uphill slopes and whenreaching in or out in order to replenish the oil level within the accumulator(s) to retainoptimum float capability.Without Lift FloatWith Lift Float- Will require constant operator input. - Automatically follows ground contours.Lift float operation when supplied as a factory fitted option is controlled from the controlsunit that accompanied the machine (refer to controls section for details), but the feature isalso available for a range of models as an after market kit, in which case operation willeither be via an auxiliary switch on cable controlled machines, or by utilisation of theauxiliary three-position type switch on the control unit of electric controlled machines - thiswill allow for selection of ‘lift float alone’ or ‘lift and angle float in unison’ if both features arefitted. Operation of the lift float control for these models will then be as specified in themain controls section.Power Connection on Cable MachinesOn cable controlled machines the switch supplied will need to be mounted in a convenientlocation in the cab. The supply cable from the poppet valve solenoid must be connectedinto the tractors ignition system - the brown lead is positive and the blue lead is negative.Power Connection on Electric MachinesOn electric controlled machines power to the unit is via the following connections:Machines with 14 core looms use connection 10 and common connection 11.Machines with 19 core looms use connection 15 and common connection 16.V4 Non-EDS proportional machines use connections LF and C.Depending on the particular machine after market lift float kits will either be frame mountedor ram mounted – they should be fitted and positioned in a location where they do not foulor interfere with other components during normal movements of the machine.63

ANGLE FLOAT KIT (Standard Feature)Machines are fitted with Angle Float as standard – when activated the feature connects thebase and gland circuits of the angle ram to allow free movement of oil in both directionsthus allowing the head to automatically angle itself to match the contours of the ground.Refer to specific controls section for details of operation.NOTE: On machines with V4 proportional controls any operation of the angle floatthumbwheel will override and de-activate the automatic angle float function, on release ofthe thumbwheel it will revert back to automatic angle float.Angle Float Off – Requires operator input to adjust flail head angle.Angle Float On – Flail head automatically angles itself to match the ground contours.64

GENERAL MAINTENANCEGeneral LubricationThe example illustration below indicates the general locations of lubrication points - allpoints should be greased on a daily basis and prior storage of the machine. New machinesmust be greased prior to first use.IMPORTANT: Grease newmachines before first use.Grease Points – General LocationsGearbox LubricationCheck gearbox oil level on new machines prior to first use, top up if required before usingthe machine. Change oil after an initial 50 hours of use and thereafter at annual or 500hour intervals, whichever occurs earliest.Gearbox Capacity:0.7 Litre SAE75W90 Fully Synthetic which meets the following minimum requirements;Viscosity at 40°C, cSt, 100.0 min.Viscosity at 100°C, cSt, 17.2 min.Replacing Gearbox OilDrainage of the gearbox forchanges of oil is via thedrain plug located on thebase of the gearbox.For refilling or for ‘toppingup’ the oil remove both plugsindicated opposite and fillgearbox via the filler plug toa point where the oil starts torun from the level plug orifice– replace plugs and tightensecurely.65

SERVICE SCHEDULEEvery DayGrease machine fully prior to work (and prior to storage).NOTE: New machines must be greased before initial use. Check for broken or damaged flails. Check tightness of flail nuts and bolts. Visually check for oil leaks and damaged hoses. Check all guards and safety shields are correctly fitted and undamaged. Ensure all lights are working and clean. Check oil level. Clean the cooler matrix, in dusty conditions more frequent cleaning is required.After initial 12 Hours Change return line filter element. Failure to do so will invalidate the warranty.Note; factory fitted filter elements are identified differently to replacement elements.After initial 50 Hours Change gearbox oil.Every 25 Hours Grease PTO Shaft universal joints and tubes.Every Week Check tightness of all nuts and bolts. Check gearbox oil level. Check for wear on telescopic arm pads – where applicable.Every 100 Hours Grease PTO shaft shield lubrication points.Every 500 Hours Change return line filter element. Change gearbox oil. Check condition of hydraulic oil and change if required; when changing oil newreturn line filter and suction strainer elements should be fitted and return line filterchanged again after 12 hours of work.Annually Change tank breather.PTO Shaft Lubrication66

HYDRAULIC SYSTEMOil SupplyCheck the oil level in the reservoir daily.Oil Condition & ReplacementNo fixed time period can be quoted for oil changes as operating conditions can vary widelybut a visually inspection of the oil will often indicate its current overall state. Signs of areduction in its condition will be apparent by changes in colour and appearance whencompared to new oil. Oil in poor condition can be dark, smell rancid or burnt, or in somecases be yellow, unclear or milky in appearance indicating the presence of air oremulsified water. Moisture resulting from condensation can become entrapped in the oilcausing emulsification that can block the return line filter, consequentially the filter systemwill be by-passed and the oil and any possible contaminants present will continue tocirculate without filtration risking damage to hydraulic components. All are indications orconditions that will require replacement of the oil.Hydraulic oil is a vital component of the machine; contaminated oil is the root cause of70% of all hydraulic system failures. Contamination can be reduced by the following:Cleaning around the reservoir cap before removal, and keeping the tank area clean.Use of clean containers when replenishing the system.Regular servicing of the filtration system.Filtration SystemMachines are protected by both replaceable 125 micron suction strainers and low pressure10 micron full flow return line filters – the diagram below is a ‘scaled up’ view illustratingthe filtering capability built into the hydraulic system of the machine:Suction strainersThe replaceable 125 micron suction strainers (Part No. 8401097) are fitted within thehydraulic tank and are ‘screw’ fitted with easy access for removal and replacement.Return Line FilterThe 25 micron absolute filter elements (Part No. 8401089) should be changed after thefirst 12 hours and thereafter at 500-hour intervals. It is important to note hours worked asif the filter becomes blocked an internal by-pass within the canister will operate and nosymptoms of filter malfunction will occur to jog your memory.Tank BreatherTo reduce the risk of pump cavitation it is advisable to replace the 25 micron absolute tankbreather (Part No. 8401050) on an annual basis under normal working conditions – formachines operating in dry dusty environments it is recommended that replacement beincreased to 6 monthly.67

HYDRAULIC HOSESThe condition of all hoses should be carefully checked during routine service of themachine. Hoses that have been chaffed or damaged on their outer casing should besecurely wrapped with waterproof adhesive tape to stop the metal braid from rusting.Hoses that have suffered damage to the metal braid should be changed at the earliestopportunity.Hose ReplacementBefore changing any hoses take the time to study the existing installation as the routinghas been carefully calculated to prevent hose damage during operation - always replacehoses in exactly the same location and manner. This is especially important for the flailhoses where they must be crossed, upper to lower, at the dipper and head pivots.Always replace one hose at a time to avoid the risk of wrong connections.When the hose is screwed to an additional fitting or union, use a second spanner onthe union to avoid breaking both seals.Do not use jointing compound on the threads.Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing ortrapping before tightening hose end connections.All Hydraulic Hoses (BSP) now fitted to McConnel Power Arm Hedge/Grass Cutters have‘soft seal’ connections on both flail and ram circuit hoses.Recommended torque settings for nut security are as follows:SIZE TORQUE SETTING O Ring Ref.1/4” BSP = 24 Nm or 18 lb.ft. 10 000 013/8” BSP = 33 Nm or 24 lb.ft. 10 000 021/2” BSP = 44 Nm or 35 lb.ft. 10 000 035/8“ BSP = 58 Nm or 43 lb.ft. 10 000 043/4“ BSP = 84 Nm or 62 lb.ft. 10 000 051” BSP = 115 Nm or 85 lb.ft. 10 000 06For hose unions (BSP) fitted in conjunction with bonded seals the recommended torquesettings are as follows:SIZETORQUE SETTING1/4” BSP = 34 Nm or 25 lb.ft.3/8” BSP = 75 Nm or 55 lb.ft.1/2” BSP = 102 Nm or 75 lb.ft.5/8“ BSP = 122 Nm or 90 lb.ft.3/4“ BSP = 183 Nm or 135 lb.ft.1” BSP = 203 Nm or 150 lb.ft.Safety NoteSoft seal hose connections are capable of holding pressure when the nut is only ‘fingertight’. It is therefore recommended during dismantling that the hose be manually flexed torelieve any residual pressure with the retaining nut slackened prior to completedisassembly.68

CONTROL CABLESThe control cables operate on a push/pull system with the spool centring springs alwaysreturning the spool to the neutral position when the handle is released.Care should be taken during installation and operation to ensure that the cables are nottrapped or kinked. Any abrasion or damage to the outer casing should be sealed withplastic insulation tape to avoid moisture penetrating.No routine adjustments of the cables are necessary, as they do not stretch. The threadedcollar is correctly adjusted when the lever is in a vertical position in its housing allowing anequal amount of travel in either direction.CAUTION!On no account should any attempt be made to lubricate the cables – these areassembled with a special ‘lifelong’ lubricant during manufacture and will not requireany additional lubrication.Note: Take care to ascertain the correct cable connections on both the control unit and thevalve in the event of cable replacement.69

PTO SHAFT MAINTENANCEPTO Shaft LubricationThe PTO shaft should be lubricated on a regular basis using lithium based grease – eachend of the shaft has 2 greasing points; one for lubrication of the universal joint and one forlubricating the rotating fixing ring of the shaft shield – access to the lubrication points isgained by releasing the shaft shield from its fixing ring and sliding it back along the body ofthe driveshaft – the procedure and lubrication frequency is illustrated below.Shaft shield fixing claspsInsert screwdrivers into the claspsPrise clasps open to release the shieldSlide shield back to reveal universal jointPTO Shaft ShieldLubrication PointUniversal JointLubrication PointLocation of lubrication pointsRecommended lubricating frequencySlide the shaft shield back into place after lubrication ensuring the clasps relocate correctlyin the fixing ring – always fit torque chains to the shields to stop them from rotating with theshaft during operation.70
