WARNING SKIN INJECTION HAZARD Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury. D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgical treatment. D Do not point the gun/valve at anyone or at any part of the body. D Do not put your hand or fingers over the spray tip/nozzle.
WARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury. D Ground the equipment and the object being sprayed/dispensed. Refer to Grounding on page 5. D If there is any static sparking or you feel an electric shock while using this equipment, stop spraying immediately. Do not use the equipment until you identify and correct the problem.
Installation Grounding To reduce the risk of static sparking, ground the pump, object being sprayed , and all spray/dispensing equipment used or located in the spray/dispensing area. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Be sure to ground all of this spray/dispensing equipment. 1. Pump: loosen the grounding lug locknut (W) and washer (X). Insert one end of a 1.
Installation NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing. NOTE: Accessories are available from your Graco representative. If you supply your own accessories, be sure they are adequately sized and pressure-rated to meet the system’s requirements. Fig. 2 is only a guide for selecting and installing system components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.
Installation ASSEMBLE THE PUMP D An air line lubricator (D) provides automatic air motor lubrication. Assemble the displacement pump (105) to the air motor (101) as instructed on pages 12–13. D A bleed-type master air valve (E) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING at left). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air regulator. Order Part No. 112730.
Operation/Maintenance Pressure Relief Procedure WARNING SKIN INJECTION HAZARD Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: D D D D are instructed to relieve the pressure, stop spraying/dispensing, check or service any of the system equipment, or install or clean the spray tip/nozzle.
Operation/Maintenance Starting and Adjusting the Pump 1. Refer to Fig. 2 on page 6. Connect the suction kit (T) to the pump’s fluid inlet, and place the tube into the fluid supply. 2. Be sure the air regulator (F) is closed. Then open the pump’s bleed-type master air valve (E). Hold a metal part of the spray gun (S) firmly to the side of a grounded metal pail and hold the trigger open. Now slowly open the air regulator until the pump starts. 3.

Troubleshooting Chart WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. Before servicing this equipment always make sure to Relieve the Pressure. Check all possible problems and solutions before disassembling the pump. PROBLEM CAUSE SOLUTION Pump fails to operate. Restricted line or inadequate air supply; Clear; increase air supply. closed or clogged valves. Check that valves are open.
Service WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.

Service 5. Lift the cylinder (11), displacement rod (1), and piston assembly off the intake housing (16). Remove the ball guide (27) from the intake housing, and inspect the guide surfaces. See Fig. 6. DISPLACEMENT PUMP SERVICE Disassembly When disassembling the pump, lay out all the removed parts in sequence, to ease reassembly. 6. Using a rubber mallet, drive the displacement rod (1) and piston assembly out the bottom of the cylinder (11) until the piston comes free.
Service 9. Examine the displacement rod (1) for scratches or other damage. Only if the rod needs replacement, unscrew it from the piston ball housing (12), using an adjustable wrench on the flats of the rod. 1 10. Remove and inspect the glands and v-packings (P) from the piston seat housing (14). Inspect the ball (13), and the seat (E) and guides (F) on the housing for wear or damage. See Fig. 8. 1 11. Unscrew the packing nut (2) from the outlet housing (9).
Service Reassembly 1. If it was necessary to remove the piston ball housing (12) from the displacement rod (1), clean the threads of the rod and the ball housing, and apply thread sealant. Screw the ball housing onto the rod, hand tight. Place the flats of the piston ball housing in a vise and torque the rod to 386–407 N.m (285–300 ft–lb). See Fig. 8. 2.
