WARNING
INSTRUCTIONS
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.
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 uncertain about usage, call your Graco
distributor.
DDo not alter or modify this equipment. Use only genuine Graco parts and accessories.
DCheck equipment daily. Repair or replace worn or damaged parts immediately.
DDo not exceed the maximum working pressure of the lowest rated system component. Refer to the
Technical Data on page 21 for the maximum working pressure of this equipment.
DUse fluids and solvents which are compatible with the equipment wetted parts. Refer to the Tech-
nical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.
DDo not exceed the maximum working pressure of the lowest rated system component. This equip-
ment has a 50.0 MPa, 500 bar (7252 psi) maximum working pressure.
DDo not kink or overbend hoses or use hoses to pull equipment.
DRoute hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose
Graco hoses to temperatures above 82_C (180_F) or below –40_C (–40_F).
DWear hearing protection when operating this equipment.
DDo not lift pressurized equipment.
DComply with all applicable local, state, and national fire, electrical, and safety regulations.
DDo not lift the sprayer by the lift ring when the total weight exceeds 550 lb (250 kg).

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.
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.
DBe sure the gun/valve trigger safety operates before spraying.
DLock the gun/valve trigger safety when you stop spraying.
DFollow the Pressure Relief Procedure on page 8 whenever you: are instructed to relieve pres-
sure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.
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 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/dispensed. 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 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.
DKeep a fire extinguisher in the work 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.

Installation
Grounding
To reduce the risk of static sparking, ground the pump,
object being sprayed , and all spray/dispensing equip-
ment 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 1.5 mm2 (12 ga)
minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. See Fig. 1. Con-
nect the other end of the wire to a true earth
ground. Order Part No. 237569 Ground Wire and
Clamp.
2. Air hoses: use only electrically conductive hoses.
3. Fluid hoses: use only electrically conductive fluid
hoses.
4. Air compressor: follow manufacturer’s recommen-
dations.
5. Spray gun/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
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, always hold a metal part of the
spray gun/dispensing valve firmly to the side of a
grounded metal pail, then trigger the gun/valve.
