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 20 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 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 180_F (82_C) or below –40_F (–40_C).
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.

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
surgical treatment.
DDo not point the gun at anyone or at any part of the body.
DDo not put your hand or fingers over the spray tip.
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 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 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. 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.
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 operating or 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.

Installation
NOTES:
DReference numbers and letters in parentheses in
the text refer to the callouts in the figures and
drawings.
DAlways 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.
DFig. 2 is only a guide for selecting and installing
system components and accessories. Contact your
Graco distributor for assistance in designing a
system to suit your particular needs.
Prepare the Operator
All persons who operate the equipment must be
trained in the safe, efficient operation of all system
components as well as the proper handling of all fluids.
All operators must thoroughly read all instruction
manuals, tags, and labels before operating the
equipment.
Prepare the Site
Ensure that you have an adequate compressed air
supply. Refer to the performance charts on pages 21
and 23 to find the air consumption of your sprayer.
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 19.
Keep the site clear of any obstacles or debris that
could interfere with the operator’s movement.
Have a grounded, metal pail available for use when
flushing the system.
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.
DPump: 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 (1.5 mm@) 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. For a ground wire and
clamp, order Part No. 237569.

DAir and fluid hoses: Use only electrically conductive
hoses with 500 ft (150 m) maximum combined hose
length to ensure grounding continuity.
DAir compressor: Follow manufacturer’s
recommendations.
DSpray gun or dispensing valve: Connect to a
properly grounded fluid hose and pump.
DObject being sprayed: Follow your local code.
DFluid supply container: Follow your local code.
DSolvent 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.
DTo maintain proper grounding continuity when
flushing or relieving pressure, always hold the metal
part of the spray gun firmly to the side of a
grounded metal pail, then trigger the gun.
