WARNING
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.
Use this pump only for pumping water and water–diluted cleaning solutions in a pressure washing system. Never use the pump for paint or any other coatings. Any misapplication of the pump may cause dangerous operating conditions which can result in serious injury and substantial property damage.
DThis equipment is for professional use only.
DRead all instruction manuals, tags, and labels before operating the equipment.
DUse the equipment only for its intended purpose. If you are not sure, call your Graco distributor.
DDo not alter or modify this equipment. Use only Graco parts and accessories.
DCheck equipment daily. Repair or replace worn or damaged parts immediately.
DDo not exceed the maximum working pressure stated on the equipment or in the Technical Data for your equipment. Do not exceed the maximum working pressure of the lowest rated component in your system.
DUse fluids and solvents which are compatible with the equipment wetted parts. Refer to the Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.
DHandle hoses carefully. Do not pull on hoses to move equipment.
DRoute hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose Graco hoses to temperatures above 66_C (150_F) or below –40_C (–40_F).
DWear hearing protection when operating this equipment.
DDo not move or lift pressurized equipment.
DComply with all applicable local, state, and national fire, electrical, and safety regulations.
WARNING
INJECTION HAZARD
Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause a serious injury.
D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medical attention.
DDo not point the spray gun at anyone or at any part of the body.
DDo not put hand or fingers over the spray tip.
DDo not stop or deflect fluid leaks with your hand, body, glove, or rag.
DDo not “blow back” fluid; this is not an air spray system.
DAlways have the tip guard and the trigger guard on the spray gun when spraying.
DCheck the gun diffuser operation weekly. Refer to the gun manual.
DBe sure the gun trigger safety operates before spraying.
DLock the gun trigger safety when you stop spraying.
DFollow the Pressure Relief Procedure on page 8 whenever you: are instructed to relieve pressure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.
DTighten all the fluid connections before operating the equipment.
DCheck the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately. Do not repair high pressure couplings; replace the entire hose.
DFluid hoses must have spring guards on both ends, to help protect them from rupture caused by kinks or bends near the couplings.
MOVING PARTS HAZARD
Moving parts, such as the air motor piston, can pinch or amputate your fingers.
DKeep clear of all moving parts when starting or operating the pump.
DNever operate the pump with the air motor plates removed.
DBefore checking or servicing the equipment, follow the Pressure Relief Procedure on page 8 to prevent the equipment from starting unexpectedly.

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.
DGround the equipment and the object being sprayed. Refer to Grounding on page 5.
DIf 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.
DProvide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid being sprayed.
DKeep the spray area free of debris, including solvent, rags, and gasoline.
DElectrically disconnect all equipment in the spray area.
DExtinguish all open flames or pilot lights in the spray area.
DDo not smoke in the spray area.
DDo not turn on or off any light switch in the spray area while spraying or while operating if fumes are present.
DDo not operate a gasoline engine in the spray area.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed.
DKnow the specific hazards of the fluid you are using.
DStore hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines.
DAlways wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer.

Setup
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the system as explained below. Also read the section FIRE OR EXPLOSION HAZARD on page 4.
Although water generally provides a natural electrical ground, the following equipment must be grounded if the cleaning chemical are volatile.
1.When cleaning in enclosed areas, such as storage tanks, locate the pump and air compressor outside the area and well away from it. Provide adequate ventilation. If the area you are cleaning has stored flammable materials. take appropriate precautions to avoid static sparking. Consult your local codes.
2.Pump: use a ground wire and clamp. See Fig. 1. Loosen the grounding lug locknut (W) and washer
(X). Insert one end of a 1.5 mm@ (12 ga) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order Part No.

3.Air and fluid hoses: use only electrically conductive hoses.
4.Air compressor: follow manufacturer’s recommendations.
5.Spray gun: ground through connection to a properly grounded fluid hose and pump.
6.Fluid supply container: follow your local code.
7.Object being sprayed: follow your local code.
8.Solvent pails used when flushing: follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.
9.To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.
General Information
The typical setup shown in Figure 2 is only a guide to selecting and installing required and optional components. For assistance in designing a system to suit your needs, contact your Graco representative. Refer to Figure 2 for callouts in parentheses.
