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.
Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgi-
cal treatment.
Do not point the gun at anyone or at any part of the body.
Do not put your hand or fingers over the spray tip.
Do not stop or deflect leaks with your hand, body, glove or rag.
Do not “blow back” fluid; this is not an air spray system.
Always have the tip guard and the trigger guard on the gun when spraying.
Check the gun diffuser operation weekly. Refer to the gun manual.
Be sure the gun trigger safety operates before spraying.
Lock the gun trigger safety when you stop spraying.
Follow the Pressure Relief Procedure on page 9 whenever you: are instructed to relieve pres-
sure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.
Tighten all fluid connections before operating the equipment.
Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
Permanently coupled hoses cannot be repaired; replace the entire hose.
Use 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.
Keep clear of all moving parts when starting or operating the pump.
Before servicing the equipment, follow the Pressure Relief Procedure on page 9 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.
Ground the equipment and the object being sprayed. Refer to Grounding on page 5.
If 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.
Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed.
Keep the spray area free of debris, including solvent, rags, and gasoline.
Electrically disconnect all equipment in the spray area.
Extinguish all open flames or pilot lights in the spray area.
Do not smoke in the spray area.
Do not turn on or off any light switch in the spray area while operating or if fumes are present.
Do 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.
Know the specific hazards of the fluid you are using.
Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.

General Information
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
NOTE: Always 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 for your system.
Fig. 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.

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.
1. Pump: use a 12 gauge (1.5 mm) minimum ground
wire and clamp. See Fig. 1. Loosen the grounding
lug locknut (W) and washer (X). Insert one end of
the 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.
238909.
5. Fluid supply container: follow your local code.
6. Object being sprayed: follow your local code.
7. 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.
8. 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.

Installation
Refer to the Typical Installation drawing (Fig. 2).
WARNING
A bleed-type master air valve (D) and a fluid drain
valve (J) are required in your system. These accessories help reduce the risk of serious injury, including skin injection and splashing of fluid in the eyes
or on the skin, and injury from moving parts if you
are adjusting or repairing the pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
Order Part No. 113333.
The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Order Part No. 238635.
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 23.
Air Line Accessories
Install the following accessories in the order shown in
Fig. 2, using adapters as necessary:
An air line lubricator (C) provides automatic air
motor lubrication.
A bleed-type master air valve (D) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
WARNING at left). Be sure the bleed valve is easily
accessible from the pump, and is located down-
stream from the air regulator.
A pump runaway valve (B) senses when the
pump is running too fast and automatically shuts off
the air to the motor. A pump which runs too fast can
be seriously damaged.
An air regulator (E) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream from the bleed-type master air valve.
An air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
Air and Fluid Hoses
Ensure that you have an adequate compressed air
supply. Refer to the performance chart on page 20 to
find the air consumption of your pump.
Be sure all air and fluid hoses are properly sized and
pressure-rated for your system. Use only electrically
conductive air and fluid hoses. Fluid hoses must have
spring guards on both ends.
Connect an electrically conductive fluid hose (L) to the
pump’s 3/8 npt(f) fluid outlet. Use of a short whip hose
between the main fluid hose (L) and the gun (M) allows
freer gun movement.
Connect a fluid suction hose or tube (N) to the pump’s
3/4 npt(m) fluid intake.
Use an electrically conductive 1/2 in. I.D. (minimum)
air hose (H) to supply air to the pump.
A second bleed-type air valve (G) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
Fluid Line Accessories
Install the following accessories in the positions shown
in Fig. 2, using adapters as necessary:
A fluid drain valve (J) is required in your system
to relieve fluid pressure in the hose and gun (see
the WARNING at left). Install the drain valve pointing down, but so the handle points up when the
valve is opened.
A fluid filter (K) filters harmful particles from the
fluid.
A spray gun (M) dispenses the fluid. The gun
shown in Fig. 2 is an airless spray gun.
