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 at anyone or at any part of the body. D Do not put your hand or fingers over the spray tip.
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. 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 NOTES: D Reference numbers and letters in parentheses in the text refer to the callouts in the figures and drawings. D Always use Genuine Graco Parts and Accessories, available from your Graco distributor. If you supply your own accessories, be sure they are adequately sized and pressure-rated to meet the system’s requirements. D Pump: Use a ground wire and clamp. See Fig.1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.
Installation Typical Installation KEY A B C D Pump Wall bracket Air line lubricator Bleed-type master air valve (required for pump) See Warning on page 7 for part number. E Pump air regulator F Air line filter G Bleed-type master air valve (for accessories) H H Electrically conductive air supply hose J Fluid drain valve (required) See Warning on page 7 for part numbers.
Installation System Accessories WARNING A bleed-type master air valve (D) and a fluid drain valve (J) are required in your system. These accessories help reduce the risk of serious injury including skin injection, splashing in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump. The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly.
Operation Pressure Relief Procedure WARNING SKIN INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury.
Operation WARNING COMPONENT RUPTURE HAZARD To reduce the risk of overpressurizing your system, which could cause component rupture and serious injury, never exceed the specified maximum air input pressure to the pump (see Technical Data on page 20). 10. Control the pump speed and fluid pressure with the air regulator (E). Always use the lowest air pressure necessary to get the desired results. Higher pressure causes premature spray tip and pump wear. 11.
Troubleshooting WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. Problem Pump fails to operate. 1. Relieve the pressure. 2. Check all possible problems and solutions before disassembling pump. Cause Solution Restricted line or inadequate air supply. Clear; increase air supply. Insufficient air pressure; closed or clogged air valves, etc. Open; clean (be sure to use air filter). Exhausted fluid supply.
Service Disconnecting the Displacement Pump 1. Lubricate the o-ring (6) and check that it is in place on the displacement rod (103). WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. 1. Flush the pump if possible. Stop the pump at the bottom of its stroke. Relieve the pressure. 2. Disconnect the air and fluid hoses. Remove the pump from its mounting.
Service Displacement Pump Service Disassembling When disassembling the pump, lay out all removed parts in sequence to make reassembling easier. Refer to Fig. 4. NOTE: Repair Kits and Conversion Kits are available. Refer to the parts list for your pump (pages 14 to 17). For the best results, use all the new parts in the kit. Parts included in the kit are marked with one asterisk (for example, 3*). Clean all the parts thoroughly when disassembling.
