GENERAL SAFETY PRECAUTIONSThe life span of the machine can be reduced and the risk ofaccidents can increase if machine maintenance is not carriedout correctly and if service and/or repairs are not carried outprofessionally. If you need further information please contactyour nearest servicing dealer.Press the throttle lockout and make sure it returns to itsoriginal position when you release it.IMPORTANT!All servicing and repair work on the machine requiresspecial training. This is especially true of the machine′ssafety equipment. If your machine fails any of the checksdescribed below you must contact your service agent.When you buy any of our products we guarantee theavailability of professional repairs and service. If the retailerwho sells your machine is not a servicing dealer, ask him forthe address of your nearest service agent.!WARNING! Never use a machine with faultysafety equipment. The machine’s safetyequipment must be checked and maintainedas described in this section. If your machinefails any of these checks contact yourservice agent to get it repaired.Throttle lockoutThe throttle lockout is designed to prevent accidentaloperation of the throttle control. When you press the lock (A)(i.e. when you grasp the handle) it releases the throttle control(B). When you release the handle the throttle control and thethrottle lockout both move back to their original positions. Thismovement is controlled by two independent return springs.This arrangement means that the throttle control isautomatically locked at the idle setting.Check that the throttle control and throttle lockout move freelyand that the return springs work properly.See instructions under the heading Start. Start the hedgetrimmer and apply full throttle. Release the throttle trigger andcheck that the blades stop and remain stationary. If the bladesmove when the throttle trigger is in the idle position then thecarburettor idle setting must be adjusted. See instructionsunder the heading Maintenance.Stop switchUse the stop switch to switch off the engine.Make sure the throttle control is locked at the idle settingwhen the throttle lockout is released.Start the engine and make sure the engine stops when youmove the stop switch to the stop setting.Hand guardThe hand guard prevents hands from coming into contact withthe moving blades, for example, if the operator loses grip onthe front handle.Check that the hand guard is fitted correctly.Check that the hand guard is undamaged.English – 7

GENERAL SAFETY PRECAUTIONSVibration damping systemNever use a machine that has a faulty muffler.Your machine is equipped with a vibration damping systemthat is designed to reduce vibration and make operationeasier.The machine′s vibration damping system reduces the transferof vibration between the engine unit/cutting equipment andthe machine′s handle unit. The engine body including theblades is suspended on the handlebar system via a foursprings.Regularly check that the muffler is securely attached to themachine.Regularly check the vibration damping units for cracks ordeformation. Check that the vibration damping element isundamaged and securely attached.If the muffler on your machine is fitted with a spark arrestorscreen this must be cleaned regularly. A blocked screen willcause the engine to overheat and may lead to seriousdamage.!MufflerWARNING! Overexposure to vibration canlead to circulatory damage or nerve damagein people who have impaired circulation.Contact your doctor if you experiencesymptoms of overexposure to vibration.Such symptoms include numbness, loss offeeling, tingling, pricking, pain, loss ofstrength, changes in skin colour orcondition. These symptoms normally appearin the fingers, hands or wrists. The riskincreases at low temperatures.The muffler is designed to keep noise levels to a minimumand to direct exhaust fumes away from the user. A mufflerfitted with a catalytic converter is also designed to reduceharmful exhaust gases.In countries that have a warm and dry climate there is asignificant risk of fire. We therefore fit certain mufflers with aspark arrestor screen. Check whether the muffler on yourmachine is fitted with this kind of screen.!!!WARNING! Mufflers fitted with catalyticconverters get very hot during use andremain so for some time after stopping. Thisalso applies at idle speed. Contact can resultin burns to the skin. Remember the risk offire!WARNING! The inside of the muffler containchemicals that may be carcinogenic. Avoidcontact with these elements in the event of adamaged muffler.WARNING! Bear in mind that:The exhaust fumes from the engine are hotand may contain sparks which can start afire. Never start the machine indoors or nearcombustible material!For mufflers it is very important that you follow the instructionson checking, maintaining and servicing your machine.8 – English

GENERAL SAFETY PRECAUTIONSBladesTo ensure good cutting results it is important that the contactpressure between the blades is correct. The contact pressureis adjusted by turning the screws on the underside of the barclockwise as far as they will go. Then turn the screwsanticlockwise a 1/4 turn. Lock the screws using the locking nuton the top of the bar. Check that the screws are loose enoughto allow the washers under the screw heads to slide sideways.When the blades are correctly adjusted the play between theblades should be 0,2–0,4 mm, measured at the screws.The edges of the blades are too hard to be filed. Dull bladesshould be sharpened using a grinder.Replace the blades if they are bent or damaged.Blade guardThe blade guard (A) is intended to protect against any part ofthe body coming into contact with the blades (B).ABCheck that the blade guard is not damaged or distorted.Replace the blade guard if it is bent or damaged.GearThe gear housing gets hot when the machine has been inuse. To avoid burning yourself do not touch the gear housing.English – 9

FUEL HANDLINGFuel safetyGasolineNever start the machine:1 If you have spilled fuel on it. Wipe off the spillage and allowremaining fuel to evaporate.2 If you have spilled fuel on yourself or your clothes, changeyour clothes. Wash any part of your body that has come incontact with fuel. Use soap and water.3 If the machine is leaking fuel. Check regularly for leaksfrom the fuel cap and fuel lines.Transport and storage• Store and transport the machine and fuel so that there isno risk of any leakage or fumes coming into contact withsparks or naked flames, for example, from electricalmachinery, electric motors, electrical relays/switches orboilers.• When storing and transporting fuel always use approvedcontainers intended for this purpose.• When storing the machine for long periods the fuel tankmust be emptied. Contact your local gas station to find outwhere to dispose of excess fuel.• Ensure the machine is cleaned and that a completeservice is carried out before long-term storage.• The transport guard must always be fitted to the cuttingattachment when the machine is being transported or instorage.• Secure the machine during transport.!FuelCAUTION! The machine is equipped with a two-strokeengine and must always been run using a mixture of gasolineand two-stroke engine oil. It is important to accuratelymeasure the amount of oil to be mixed to ensure that thecorrect mixture is obtained. When mixing small amounts offuel, even small inaccuracies can drastically affect the ratio ofthe mixture.!WARNING! Take care when handling fuel.Bear in mind the risk of fire, explosion andinhaling fumes.WARNING! Fuel and fuel fumes are highlyinflammable and can cause serious injurywhen inhaled or allowed to come in contactwith the skin. For this reason observecaution when handling fuel and make surethere is adequate ventilation.CAUTION! Always use a quality gasoline/oil mixture with anoctane rating of at least 87 octane ((RON+MON)/2). If yourmachine is equipped with a catalytic converter (see chapteron Technical data) always use a good quality unleadedgasoline/oil mixture. Leaded gasoline will destroy the catalyticconverter.Use low-emission gasoline, also known as alkylate gasoline,if it is available.This engine is certified to operate on unleaded gasoline.• The lowest recommended octane grade is 87((RON+MON)/2). If you run the engine on a lower octanegrade than 87 so-called knocking can occur. This givesrise to a high engine temperature and increased bearingload, which can result in serious engine damage.• When working at continuous high revs a higher octanerating is recommended.Two-stroke oil• For best results and performance use JONSERED twostrokeengine oil, which is specially formulated for our aircooledtwo stroke-engines.• Never use two-stroke oil intended for water-cooledengines, sometimes referred to as outboard oil (ratedTCW).• Never use oil intended for four-stroke engines.• Mixing ratio1:50 (2%) with JONSERED two-stroke oil.Gasoline, litreTwo-stroke oil, litre2% (1:50)5 0,1010 0,2015 0,3020 0,40US gallon US fl. oz.1 2 1/22 1/2 6 1/25 12 7/810 – English

FUEL HANDLINGMixing• Always mix the gasoline and oil in a clean containerintended for fuel.• Always start by filling half the amount of the gasoline to beused. Then add the entire amount of oil. Mix (shake) thefuel mixture. Add the remaining amount of gasoline.• Mix (shake) the fuel mixture thoroughly before filling themachine’s fuel tank.• Do not mix more than one month’s supply of fuel at a time.• If the machine is not used for some time the fuel tankshould be emptied and cleaned.!WARNING! The catalytic converter mufflergets very hot during and after use. This alsoapplies during idling. Be aware of the firehazard, especially when working nearflammable substances and/or vapours.Fueling!WARNING! Taking the following precautions,will lessen the risk of fire:Do not smoke or place hot objects near fuel.Always shut off the engine before refuelling.Always stop the engine and let it cool for afew minutes before refuelling.When refuelling, open the fuel cap slowly sothat any excess pressure is released gently.Tighten the fuel cap carefully after refuelling.Always move the machine away from therefuelling area before starting.• Clean the area around the fuel cap. Contamination in thetank can cause operating problems.• Ensure that the fuel is well mixed by shaking the containerbefore filling the tank.English – 11

When thehandle is adjusted the hedge trimmer should be idling ornot running.• While working the handle should always be facingupwards irrespective of how the hedge trimmer isdirected.14 – English

MAINTENANCECarburetorAdjusting the idle speedThe T-screw regulates the throttle setting at idle speed. If theT-screw is turned clockwise this gives a higher idle speed;turning it anti-clockwise gives a lower idle speed.Before any adjustments are made, make sure that the air filteris clean and the air filter cover is fitted.Adjust the idle speed with the idle adjustment screw T, ifadjustment is necessary. First turn the idle adjustment screwT clockwise until the blades start to move. Then turn the idleadjustment screw T anticlockwise until the blades stop. Theidle speed is correctly adjusted when the engine runssmoothly in every position. There should also be a clearmargin to the speed at which the blades start to move. Theblades must also remain stationary when the choke control isin the start throttle position.On mufflers without a catalytic converter the screen should becleaned weekly, or replaced if necessary. On mufflers fittedwith a catalytic converter the screen should be checked, andif necessary cleaned, monthly. If the screen is damaged itshould be replaced. If the screen is frequently blocked, thiscan be a sign that the performance of the catalytic converteris impaired. Contact your dealer to inspect the muffler. Ablocked screen will cause the machine to overheat and resultin damage to the cylinder and piston. See also instructionsunder the heading Maintenance.CAUTION! Never use a machine with a defective muffler.!WARNING! Mufflers fitted with catalyticconverters get very hot during use andremain so for some time after stopping. Thisalso applies at idle speed. Contact can resultin burns to the skin. Remember the risk offire!Cooling systemTo keep the working temperature as low as possible themachine is equipped with a cooling system.!WARNING! If the idle speed cannot beadjusted so that the cutting attachmentstops, contact your dealer/serviceworkshop. Do not use the machine until ithas been correctly adjusted or repaired.21MufflerThe cooling system consists of:CAUTION! Some mufflers are fitted with a catalyticconverter. See chapter on Technical data to see whether yourmachine is fitted with a catalytic converter.The muffler is designed to reduce the noise level and to directthe exhaust gases away from the operator. The exhaustgases are hot and can contain sparks, which may cause fireif directed against dry and combustible material.1 Cooling fins on the cylinder.2 Cylinder cover (directs cold air over the cylinder).Clean the cooling system with a brush once a week, moreoften in demanding conditions. A dirty or blocked coolingsystem results in the machine overheating which causesdamage to the piston and cylinder.Spark plugThe spark plug condition is influenced by:• Incorrect carburetor adjustment.Some mufflers are equipped with a special spark arrestorscreen. If your machine has this type of muffler, you shouldclean the screen at least once a week. This is best done witha wire brush.• An incorrect fuel mixture (too much or incorrect type ofoil).• A dirty air filter.These factors cause deposits on the spark plug electrodes,which may result in operating problems and startingdifficulties.English – 15

MAINTENANCEIf the machine is low on power, difficult to start or runs poorlyat idle speed: always check the spark plug first before takingany further action. If the spark plug is dirty, clean it and checkthat the electrode gap is 0.7 mm (0,028"). The spark plugshould be replaced after about a month in operation or earlierif necessary.Put the filter in a plastic bag and pour the filter oil over it.Knead the plastic bag to distribute the oil. Squeeze theexcess oil out of the filter inside the plastic bag and pour offthe excess before fitting the filter to the machine. Never usecommon engine oil. This would drain through the filter quitequickly and collect in the bottom.GearCAUTION! Always use the recommended spark plug type!Use of the wrong spark plug can damage the piston/cylinder.Check that the spark plug is fitted with a suppressor.Air filterThere is a grease nipple and a plug for filling lubricant on thegear housing. Use a grease gun to fill with grease. This shouldbe done after every 60 working hours. Use Jonsered specialgrease.The air filter must be regularly cleaned to remove dust and dirtin order to avoid:• Carburettor malfunctions• Starting problems• Loss of engine power• Unnecessary wear to engine parts• Excessive fuel consumption.Clean the filter every 25 hours, or more regularly if conditionsare exceptionally dusty.CAUTION! The gear housing must not be filled completelywith grease. The grease expands as the machine heats upduring operation. If the gear housing was completely filledwith grease it could damage the seals and lead to leakage ofgrease.The grease in the bevel gear does not normally need to bechanged except if repairs are carried out.Cleaning and lubricationCleaning the air filterRemove the air filter cover and take out the filter. Wash itclean in warm, soapy water. Ensure that the filter is dry beforerefitting it.An air filter that has been in use for a long time cannot becleaned completely. The filter must therefore be replaced witha new one at regular intervals. A damaged air filter mustalways be replaced.If the machine is used in dusty conditions the air filter shouldbe soaked in oil. See instructions under the heading Oiling theair filter.Oiling the air filterAlways use special filter oil. Filter oil contains a solvent tomake it spread evenly through the filter. You should thereforeavoid skin contact.Clean any resin and plant residue from the blades usingcleaning agent before and after using the machine.Lubricate the blade bars with special grease before longperiods of storage.IMPORTANT! Use only JONSERED replacement parts.Use of other brands of replacement parts can causedamage to your unit or injury to the operator or others. Yourwarranty does not cover damage or liability caused by theuse of accessories and/or attachments not specificallyrecommended by JONSERED.16 – English
