Warnings Warning Symbol Caution Symbol WARNING CAUTION This symbol alerts you to the possibility of serious injury or death if you do not follow the instructions. This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the corresponding instructions. WARNING EQUIPMENT MISUSE HAZARD Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury. INSTRUCTIONS D This equipment is for professional use only.
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 7. 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 WARNING CAUTION The maximum safe hydraulic input pressure to this motor depends on the lower displacement pump to which it is connected. Recommended Hydraulic Oil Use Graco-approved Hydraulic Oil, Part No. 169236 (5 gal) or 207428 (1 gal)) or a premium, ISO grade 46 petroleum-based hydraulic oil containing rust and oxidation inhibitors and anti-wear agents.
Installation Grounding WARNING For your safety, read the FIRE AND EXPLOSION HAZARD WARNINGS on page 5, and ground your entire system as instructed below. This section also includes details on how to connect the grounding wire and clamp to the various hydraulic motors. Proper grounding is an essential part of maintaining a safe system. To reduce the risk of static sparking, ground the pump. Check your local electrical code for detailed grounding instructions for your area and type of equipment.
Service 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.
Service Disassembly (continued – refer to Fig. 3) CAUTION When removing the displacement pump, hold it securely. The pump is heavy and could fall off the motor. 5. Disconnect the displacement pump from the motor, as explained in your separate pump manual. 6. Place the hydraulic motor in a bench vise. 7. Push or lightly tap the piston (49) up as far as possible. NOTE: The tie rod nuts (3), socket screws (8), cap– screws (24), and retainer (32) are fastened with Loctiter TL–242.
