WARNING
SKIN INJECTION HAZARD
Spray from the gun/valve, 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.
DFluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgi-
cal treatment.
DDo not point the gun/valve at anyone or at any part of the body.
DDo not put your hand or fingers over the spray tip/nozzle.
DDo not stop or deflect 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 gun when spraying.
DCheck the gun diffuser operation weekly. Refer to the gun manual.
DBe sure the gun/valve trigger safety operates before spraying/dispensing.
DLock the gun/valve trigger safety when you stop spraying/dispensing.
DFollow the Pressure Relief Procedure on page 6 whenever you: are instructed to relieve pres-
sure; stop spraying/dispensing; clean, check, or service the equipment; and install or clean the
spray tip/nozzle.
DTighten all fluid connections before operating the equipment.
DCheck the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
Permanently coupled hoses cannot be repaired; replace the entire hose.
DUse only Graco approved hoses. Do not remove any spring guard that is used to help protect the
hose 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.
DBefore servicing the equipment, follow the Pressure Relief Procedure on page 6 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 spray-
ing/dispensing 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/dispensed.
DKeep the spray/dispense area free of debris, including solvent, rags, and gasoline.
DElectrically disconnect all equipment in the spray/dispense area.
DExtinguish all open flames or pilot lights in the spray/dispense area.
DDo not smoke in the spray/dispense area.
DDo not turn on or off any light switch in the spray/dispense area while operating or if fumes are
present.
DDo not operate a gasoline engine in the spray/dispense area.
DThis pump is specifically designed with non-sparking construction. Interchange of any parts for
repair or improvement of the pump, including the air motor, must be with identical parts bearing the
same part numbers given on page 13–15. To reduce the risk of fire or explosion and serious injury,
the use of any other parts is prohibited.
DNever use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents in pressurized aluminum equipment. Such use could result in a
chemical reaction, with the possibility of explosion.
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.

Installation
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
To reduce the risk of static arcing, ground the pump and
all other spray equipment used or located in the spray
area. CHECK your local electrical code for detailed
grounding instructions for your area and type of equip-
ment. BE SURE to ground all of this spray equipment:
1. Pump: loosen grounding lug locknut (A) and washer.
Insert one end of a 12 ga (1.5 mm2) minimum
groundwire (B) into slot in lug (C) and tighten locknut
securely. See Fig. 1. Connect the other end of the
wire to a true earth ground. Always check your local
code. Order Part No. 237569.
2. Air hoses: use only electrically conductive air hoses.
3. Fluid hoses: use only electrically conductive fluid
hoses.
4. Air compressor: follow the manufacturer’s recom-
mendations.
5. Dispensing valve: grounding is obtained through
connection to a properly grounded fluid hose and
pump.
6. Fluid supply container: according to your local code.
7. Object being sprayed: according to your local code.
8. All solvent pails used when flushing, according to lo-
cal code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the pail
on a non–conductive surface, such as paper or card-
board, which interrupts the grounding continuity.
9. To maintain grounding continuity when flushing or re-
lieving pressure, always hold a metal part of the valve
firmly to the side of a grounded metal pail, then trig-
ger the valve.
