equipment has a 180 psi (12 bar, 1.2 MPa) maximum incoming air pressure.
D Use 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.
D Do not use hoses to pull equipment.

D Comply with all applicable local, state, and national fire, electrical, and safety regulations.
WARNING
SKIN INJECTION HAZARD
Spray from the gun/dispensing valve, 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.
D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate
surgical treatment.
D Do not point the gun/valve at anyone or at any part of the body.
D Do not put your hand or fingers over the spray tip/nozzle.
D Do not stop or deflect leaks with your hand, body, glove or rag.
D Do not “blow back” fluid; this is not an air spray system.
D Always have the tip guard and the trigger guard on the gun/valve when spraying.
D Check the gun diffuser operation weekly. Refer to the gun manual.
D Be sure the gun trigger safety operates before spraying.
D Lock the gun trigger safety when you stop spraying.
D Follow the Pressure Relief Procedure on page 6 if the spray tip/nozzle clogs and before clean-
ing, checking or servicing the equipment.
D Tighten all fluid connections before operating the equipment.
D Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Do not repair high pressure couplings; you must replace the entire hose.
D Use only Graco approved hoses. Do not remove the 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.
D Keep clear of all moving parts when starting or operating the pump.
D Before 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.
D Ground the equipment and the object being sprayed. Refer to Grounding on page 5.
D If 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.
D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed/dispensed.
D Keep the spray/dispense area free of debris, including solvent, rags, and gasoline.
D Electrically disconnect all equipment in the spray/dispense area.
D Extinguish all open flames or pilot lights in the spray/dispense area.
D Do not smoke in the spray/dispense area.
D Do not turn on or off any light switch in the spray/dispense area while operating or if fumes are
present.
D Do not operate a gasoline engine in the spray/dispense 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.
D Know the specific hazards of the fluid you are using.
D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
D Always 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.
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this equipment:
1. Pump: use a ground wire and clamp as shown in
Fig. 1.
2. Air and fluid hoses: use only electrically conductive
hoses.
5. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
gun/valve firmly to the side of a grounded metal
pail, then trigger the gun/valve.
To ground the pump:
To ground the pump, 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. Order 222011,
Ground Wire and Clamp.

3. Air compressor: follow manufacturer’s recommendations.
4. Fluid supply container: according to local code.

Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying/dispensing accidentally. Fluid under high pressure can be injected
through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing
fluid, or moving parts, follow the Pressure Relief
Procedure whenever you:
D are instructed to relieve the pressure,
D stop spraying/dispensing,
D check or service any of the system equipment,
D or install or clean the spray tip/nozzle.
1. Close the pump air regulator and the bleed-type
master air valve (required in your system).
2. Hold a metal part of the spray gun/dispensing
valve firmly to a grounded metal waste container
and trigger the gun/valve to relieve the fluid pressure.
Before You Start
D Be sure you have all necessary parts on hand.
Air Motor Repair Kit 206728 includes repair parts
for the motor. Use all the parts in the kit for the best
results. Parts included in the kit are marked with an
asterisk, for example (19*), in the text and drawings. See Parts List on pages 10 – 14.
D For best results keep parts marked with one aster-
isk on hand to reduce down time.
Disassembly
1. Flush the pump.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure above.
2. Relieve the pressure.
3. Remove the pump according to the instructions in
the pump manual.
4. Place the air motor base (F) in a vise with the air
motor up.
5. Loosen the cap nut (B). Pull up the cap nut, grip
the trip rod (C) with the padded pliers, and screw
the cap nut off of the rod.
CAUTION
Do not damage the plated surface of the trip rod (C).
Damaging the surface of the trip rod can result in
erratic air motor operation. Use the special padded
pliers 207579 to grasp the rod.
6. Remove the six screws (D) holding the cylinder (E)
to the base (F). Carefully pull the cylinder straight
up off of the piston assembly (G).
D Two accessory tools should be used: Padded
Pliers, 207579, are used to grip the trip rod without
damaging its surface, and a 0.145-in. (3.7 mm)
Gauge, 171818, is used to assure the proper
clearance between the poppets and the piston.
6 307043
CAUTION
To avoid damaging the cylinder wall, lift the cylinder
straight up off of the piston. Never tilt the cylinder as
it is being removed.
