Accessoriesfor use with this ram are listed in the Accessoriessection on page 63.you use only electrically conductive air and fluidhoses.you ground your equipment.the fluid hoses have spring guards on both ends.Selecting a Location for the RamRefer to the Ram Mounting and Clearance Dimensionsdrawing (Fig. 7 on page 64) for ram mounting andclearance dimensions.When selecting a location for the ram, keep the followingin mind:1. There should be sufficient space for installing andusing the equipment. Make sure:there is sufficient overhead clearance for thepump and ram when the ram is in the fullyraised position.the air regulators for the pump and ram arefully accessible.2. You need to decide whether you will be bolting theram to the floor, or bolting it to a mobile platform.3. If you bolt the ram to the floor, make sure:you will be able to level the base of the ramusing metal shims.you have anchors long enough to prevent theunit from tipping. Refer to the DimensionalDrawing on page 64 for more information.4. If you bolt the ram to a mobile platform, makesure:you locate the platform on a surface where itwon’t roll around.the ram and platform are stable in all operatingpositions, so the ram won’t tip over.System AccessoriesBefore you install the system you should be familiarwith the parts discussed below. For more information,refer to Fig. 1, A Typical Installation, on page 8.To allow the gun freer movement, use a short whiphose between the main fluid hose and the gun.Air Line ModulesWARNINGPRESSURIZED FLUID HAZARD ANDMOVING PARTS HAZARDThe pump bleed-type master air valve(C) is required in your system to relieveair trapped between this valve and thepump after the pump air regulator isclosed. Trapped air can cause the pumpto cycle unexpectedly, which could resultin serious bodily injury, including splashing in theeyes or on the skin and injury from moving parts.2-Regulator Air Control Modules (918407) (Fig.1 onpage 8)The following components are included with the module:Pump Bleed-type Master Air Valve (C) is required inyour system to relieve air trapped between it andthe air motor when the valve is closed (see theWARNING above). Be sure the bleed valve iseasily accessible from the pump, and is locateddownstream from the air regulator.Pump Air Regulator (D) controls pump speed andoutlet pressure by adjusting the air pressure to thepump. Locate the regulator close to the pump, butupstream from the bleed-type master air valve.Ram Air Regulator (not shown) controls the airpressure to the ram.Ram Air Supply Hose (H) connects the ram airregulator to the air manifold.Air Manifold (F) divides the main air supply intoseparate lines for the pump and ram.310526 9

Typical InstallationThe following components are included with the module:Pump Bleed-type Master Air Valve is required inyour system to relieve air trapped between it andthe air motor when the valve is closed (see theWARNING above). This bleed valve should beeasily accessible and located downstream from theair regulator. It can be used for a safety lockout.Pump Air Regulator controls pump speed and outletpressure by adjusting the air pressure to the pump.It is located on the air control panel upstream fromthe bleed-type master air valve.Ram Air Regulator controls the air pressure to theram. There are separate air regulators to controlthe ram pressure in the up and down directions.Ram Air Supply Hose connects the ram air regulatorto the air manifold.FRL (filter, regulator, lubricator) conditions the air tothe ram and the pump. The pump air regulator islocated in this assembly. The ram air is taken fromthis assembly; an air line tube connects the FRLand the ram air control module.Air Line AccessoriesInstall the following accessories in the order shown inthe Typical Installation, using adapters as necessary:Pump runaway valve (not shown) senses when thepump is running too fast and automatically shuts offthe air to the motor. A pump that runs too fast canbe seriously damaged.Air line lubricator (I) provides automatic air motorlubrication (standard on the 4-Regulator Air ControlModule).Air line filter (A) removes harmful dirt and moisturefrom the compressed air supply (standard on the4-Regulator Air Control Module).Accessory bleed-type air valve (B) isolates the airline accessories for servicing. Locate upstreamfrom all other air line accessories. This isolates theaccessories for servicing.Fluid Line AccessoriesInstall the following accessories in the positions shownin the Typical Installation drawing, using adapters asnecessary:A fluid drain valve (J) is required in your system torelieve fluid pressure in the hose and gun (see theWARNING on page 9). When you install the fluiddrain valve:1. Screw the drain valve into the open branch ofa tee mounted in the fluid line.2. Install the drain valve pointing down, and sothe handle points down when the valve isopened.A fluid regulator (K) controls fluid pressure to thegun/valve, and dampens pressure surges.A gun or valve (L) dispenses the fluid. The gunshown in the Typical Installation is a dispensing gunfor highly viscous fluids.A gun swivel (M) allows freer gun movement.10310526

OperationWARNINGMOVING PARTS HAZARDFollow the Pressure Relief Procedurebelow before checking or repairing theram or any other part of the system andwhen shutting down the system. Keep hands andfingers away from the follower plate, fluid pumpinlet, and lip of the fluid container when raising orlowering the ram to reduce the risk of pinching oramputating hands or fingers.During operation, also keep hands and fingersaway from limit switches to reduce the risk ofpinching or amputating hands or fingers.Pressure Relief ProcedureSKIN INJECTION HAZARDThe system pressure must be manuallyrelieved to prevent the system fromstarting or spraying accidentally. Fluidunder high pressure can be injected through theskin and cause serious injury. To reduce the risk ofan injury from injection, splashing fluid, movingparts, follow the Pressure Relief Procedurewhenever you:are instructed to relieve the pressurestop spraying/dispensingWARNINGcheck or service any of the system equipmentinstall or clean the spray tip/nozzle4. Unlock the gun/valve trigger safety.5. Hold a metal part of the gun/valve firmly to the sideof a grounded metal pail, and trigger the gun/valveto relieve pressure.6. Lock the gun/valve trigger safety.7. Have a container ready to catch the drainage, thenopen the drain valve or pump bleed valve.8. Leave the drain valve open until you are ready tospray/dispense again.If you suspect that the spray tip/nozzle or hose iscompletely clogged, or that pressure has not been fullyrelieved after following the steps above, very slowlyloosen the tip guard retaining nut or hose end couplingto relieve pressure gradually, then loosen completely.Now clear the tip/nozzle or hose.9. If you want to relieve pressure in the ram, see theRam Pressure Relief Procedure in Form#310525.Raising and Lowering the RamThe ram hand valve on the pump air control has 3positions (Fig. 5):Ram UP raises the ram. When removing ram platefrom drum, it is necessary to use follower blowoff toavoid creating a vacuum in drum.Ram DOWN lowers the ram.Ram OFF puts the ram in “neutral.” Moving thehand valve to OFF does not change the position ofthe ram, but it stops the air pressure from attemptingto move the ram either up or down.Ram UPUse this procedure whenever you shut off the sprayerand before checking or adjusting any part of thesystem, to reduce the risk of serious injury.1. Lock the gun/valve trigger safety.2. Shut off the main air supply to the pump.3. Close all air bleed valves.Fig. 5Ram OFF (neutral)Ram DOWN310526 13

OperationPreparing to Pump FluidFollow the steps below to prepare the system forpumping fluid. Refer to the Typical Installation Drawing,(Fig. 1 on page 8) for more information.1. Move the hand valve lever to the OFF position(Fig. 5). Close the ram air regulator and main aircontrol valve.2. Move the hand valve lever to the UP position(Fig. 5). Open the main air control valve and ramair regulator until the ram starts to move upward.Let the ram rise to its full height.3. Set a full pail of fluid on the ram base and center itunder the follower plate.NOTE: Do not use pails that have side bungs or largedents with this ram. Rough bung openings or largedents will damage the wiper or stop the follower plate,resulting in a runaway pump.4. Move the hand valve lever to the DOWN position(Fig. 5) and lower the ram until the follower plate isjust ready to enter the pail, then move the handvalve lever to OFF. If necessary, reposition the pailso the wiper will not hit the pail lip.5. Unscrew the follower plate’s bleed handle (see Fig.1, item (8) on page 8).6. Move the hand valve lever to the DOWN position(Fig. 5), to lower the follower plate into the pail,until all air is forced out and fluid comes out of thevent opening.7. Move the hand valve lever to OFF and screw inthe bleed handle (see Fig. 1, item (8) on page 8).8. Set the air pressure to the ram at 345 kPa, 3.4 bar(50 psi). Move the hand valve lever to the DOWNposition (Fig. 5).9. Slowly start the pump by opening both the bleedtypemaster air valve and the fluid dispensingvalve. Do not allow the pump to cycle too quickly.Let the pump run until the system is primed and allair is forced out.10. Stop the pump by closing either the bleed-typemaster air valve or the fluid dispensing valve.NOTE: Increase air pressure to the ram if the pumpdoes not prime properly with heavier fluids. If fluid isforced out around the top wiper, ram pressure is toohigh and the air pressure should be decreased.Pumping FluidTo pump fluid from the pail:1. Move the hand valve lever to the DOWN position(Fig. 5).2. Open the bleed-type master air valve.3. Start the pump by opening the pump air regulator.Then adjust the pump for normal operation.Always use the lowest possible air pressure to both thepump and ram.WARNINGDo not overpressurize the system, as this couldresult in serious injury or damage to the equipment.NOTE: It is normal for the pump to stall if the dispensegun or other fluid valve is closed.Changing PailsTo change pails:1. Stop the pump by closing either the bleed-typemaster air valve or the fluid dispensing valve, andthen moving the hand valve lever to UP (Fig. 5).Carefully equalize pressure in the drum by usingthe follower blowoff button.2. Raise the wiper plate until it is completely out ofthe drum.3. When the ram reaches its maximum height, movethe hand valve to OFF (Fig. 5).4. Remove the empty pail and put a full pail in itsplace.5. Perform the procedure, Preparing to PumpFluid, above.14310526

OperationShutdown1. Move the hand valve lever to the OFF position(Fig. 5). Shut off the air supply to the ram andpump.WARNINGTo reduce the risk of serious injury whenever youare instructed to relieve pressure, always follow thePressure Relief Procedure (page 13).2. Relieve the pressure.Emergency Stop1. To stop the ram from moving, move the hand valve(Fig. 5) the OFF position.2. To stop the pump, close the Bleed-type Master AirValve closest to the motor’s air inlet [see Fig. 1,item (C) on page 8].Flushing SafetyWARNINGTo reduce the risk of serious injury whenever youare instructed to relieve pressure, always follow thePressure Relief Procedure (page 13).2. Relieve the pressure.WARNINGPRESSURIZED FLUID HAZARDAlways use the lowest possible fluidpressure, and maintain firm metal-tometalcontact between the gun/valveand the pail during flushing to reduce the risk offluid injection injury, static sparking and splashing.3. Remove the spray tip/nozzle from the spray gun/dispensing valve.Inspection FrequencyPeriodically (once a month), inspect the ram guidesleeves, rods and cylinders for wear or damage,replace all worn parts. See the Service section ofForm# 310525 for instructions on replacing worn parts.See the pump instruction manual for its inspectionfrequency.1.
