InstallationTo install the ram on a mobile platform:1. Brace the platform so it remains stationary whileyou attach the ram to the platform.2. Place the ram on the platform and line up theholes in its base with the holes in the platform.3. Secure the ram to the platform with the providednuts and bolts.4. Now you are ready to install the pump. Go to theInstalling the Pump section on page 12.Installing the Pumpii.Connect air lines from the bottom side ofthe cylinders to the bottom fitting on thehand valve.4. Attach the follower to the pump assembly:a. Use the hand valve (3) on the pump air controlto raise the pump assembly to the UP position(Fig. 3).3To install the pump, follow the procedure below. Referto Fig. 1, A Typical Installation, on page 8, for moreinformation.1. Attach the pump assembly to the ram:a. Place the pump assembly onto the pumpmounting plate.b. Secure the pump assembly to the pumpmounting plate with the four 5/16 in.–18 sockethead capscrews.2. Install the pump air control module:a. Insert the air manifold stud in the hole on thepump mounting plate (N) and secure with thelockwasher and nut provided.b. Connect the air regulator kit’s hose to thepump’s air inlet.3. Attach the ram air control module to the ram:a. Insert the four supplied 1/4 in.-20 socket headcapscrews, with lockwashers, through thehand lever valve.Fig. 3b. Make sure the o-ring is already in the followerplate. If it is not already there, place it in thefollower now.c. Lubricate the o-ring.d. Push the follower up onto the end of the pumpassembly until the follower bottoms out. Thelocking bolt should be facing front.e. Tighten the locking bolts to 13.6–20.3 N.m(10–15 ft-lb).f. Connect the air hose from the follower plateblowoff to the air control module on the followerblowoff valve assembly.g. Use the hand valve (3) on the pump air controlto lower the pump to the OFF (neutral) position(Fig. 4).b. Attach the screws to the mounting bracket.c. Connect the air hose from the air controlmodule to the air manifold.3d. Connect the ram air lines to the air controlmodule:i. Connect the airlines from the top side ofthe cylinders to the top fitting on the handvalve.Fig. 412310526
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
