WARNING
This symbol alerts you to the possibility of serious
injury or death if you do not follow the instructions.
Caution Symbol
CAUTION
Alerts you to the possibility of damage to or destruction
of equipment if you do not follow the instructions.
The following are general warnings related to the safe setup, use, maintenance and
repair of this equipment. Additional, more specific warnings may be found throughout
the text of this manual where applicable.
WARNING
Fire and Explosion Hazard
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help
prevent fire and explosion:
DUse equipment in well ventilated areas only.
DDo no fill fuel tank while motor is running or hot; shut off motor and let it cool. Fuel is flammable
and can ignite or explode if spilled on hot surface.
DEliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic
drop cloths (potential static arc).
DKeep the work area free of debris, including solvent, rags, and gasoline.
DDo not plug or unplug power cords or turn lights on or off when flammable fumes are present.
Carbon Monoxide Hazard
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon
monoxide can cause death. Do not operate in an enclosed area.
INSTRUCTIONS
Equipment Misuse Hazard
Equipment misuse can cause death or serious injury.
DDo not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
DUse fluids and solvents that are compatible with equipment wetted parts. See Technical Data in
all equipment manuals. Read fluid and solvent manufacturer’s warnings.
DCheck equipment daily. Repair or replace worn or damaged parts immediately.
DDo not alter or modify this equipment.
DUse the equipment only for its intended purpose. Call your Graco distributor for information.
DFor professional use only.
DRoute hoses away from traffic areas, sharp edges, moving parts, and hot surfaces.
DDo not use hoses to pull equipment.
DComply with all applicable safety regulations.

3309916
WARNING
Burn Hazard
Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe
burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.
Pressurized Equipment Hazard
Compressed air can inject in skin. Air tubing rupture can cause injury if disconnect while under
pressure. To reduce risk of injury:
DNever exceed maximum working pressure of any attachment
DDo not direct air stream at body
DFollow Pressure Relief Procedure, page 6 whenever you are instructed to relieve pressure, stop
spraying, service equipment, install or clean spray nozzle or disconnect or connect hose.
Cleaning Solvent with Plastic Parts Hazard
Use only compatible solvents to clean plastic structural or pressure-containing parts. Many solvents
can degrade plastic parts to the point where they could fail. Such failure could cause serious injury or
property damage. See the Technical Data section on page 26 in this instruction manual and in all
other equipment manuals. Read the fluid and solvent manufacturer’s warnings.
Personal Protective Equipment
Wear appropriate protective equipment when operating, servicing, or when in the operating area of
this equipment to help protect yourself from serious injury, including eye injury, inhalation of toxic
fumes, burns and hearing loss. This equipment includes, but is not limited to:
Dprotective eye wear
Dclothing and respirator as recommended by fluid and solvent manufacturer
Dhearing protection
Dgloves
CAUTION
Water or material remaining in unit when temperatures are below freezing can damage pump and/or delay
startup.
To insure water and material are completely drained out of unit:
DRemove material line from sprayer
DTip sprayer to allow material (water) to flow out of pump inlet.
Before adding material or staring unit in cold weather, run warm water through pump.

Troubleshooting
Before performing any Troubleshooting procedures, follow Pressure Relief Procedure on page 6.
PROBLEM CAUSE SOLUTION
Compressor not building
pressure or poor air flow
Open gun air valve (23) Close valve.
Air leak Check all fittings and valve/regulator
settings.
Unloader stuttering, unloading
too early, or unloading too late.
Damaged unloader Replace.
No material output from pump Not enough air pressure to pump Shut off air at the gun, and increase
air pressure to the pump to
maximum. Turn regulator clockwise
to increase.
Material too thick Thin the material. Material must be
mixed thoroughly to a consistency
that immediately folds back in as
you draw your finger through the
surface of the material.
Damaged checkballs or seats Replace checkballs or seats.
Plugged gun or nozzle Relieve pressure, page 6. Re-
move gun from material hose, and
cycle pump.
NOTE: A plugged gun or nozzle
may cause the hose and pump to
plug. If necessary, flush hose and
pump with clean water before
cycling material through the hose
with the gun removed.
Plugged hose, or hose too small Relieve pressure, page 6. Flush
hose with clean water, or try a 1–1/4
in. hose.
Pump stops pumping Stalled pump Shut down system. Relieve pres-
sure, page 6. Restart.
Contact an authorized Graco ser-
vice center.
Engine won’t start Engine switch is OFF Turn engine switch ON.
Engine is out of gas Refill gas tank. Honda Engine
Owners Manual.
Engine oil level is low Try to start engine. Replenish oil, if
necessary. Honda Engine Owners
Manual.
Spark plug cable disconnected or
damaged
Connect spark plug cable or replace
spark plug.
Cold engine Use choke.
Fuel shutoff lever is OFF Move lever to ON position.
Oil is seeping into combustion
chamber
Remove spark plug. Pull starter 3
or 4 times. Clean or replace spark
plug. Start engine. Keep sprayer
upright to avoid oil seepage.

Troubleshooting
Pump stops pumping Pump in need of repair See texture pump instruction
manual 308479.
Pulsing or surging material Triggering too fast Slowly squeeze trigger to fully open
position while moving gun quickly in a
circular motion.
Speed of application too slow Not enough air pressure to pump Shut off air at the gun, and increase
air pressure to the pump to maxi-
mum. Turn regulator clockwise to
increase.
Material too thick Material must be mixed thoroughly
to a consistency that immediately
folds back in as you draw your fin-
ger through the surface of the ma-
terial.
Nozzle too small Increase nozzle size.
Hose plugged or too small. Relieve pressure, page 6. Clean
hose, or try a 1–1/4 in. hose.
Pump in need of repair See texture pump instruction
manual 308479.
Pattern too fine or too much
overspray
Material too thin Thicken material. Material must be
mixed thoroughly to a consistency
that immediately folds back in as
you draw your finger through the
surface of the material.
Air pressure at gun too high Decrease air to gun at gun fitting
and/or regulator.
Fluid delivery too low Increase nozzle size.
Increase air pressure to pump, or
decrease air to gun at gun fitting
and/or regulator.
Turn fluid knob out on gun. See
Spray Techniques in Operation
Manual 309915.
Pattern too coarse Material too thick Thin material. Material must be
mixed thoroughly to a consistency
that immediately folds back in as
you draw your finger through the
surface of the material.
Air pressure at gun too low Increase air to gun at gun fitting
and/or regulator.
Fluid delivery too high Decrease nozzle size.
Decrease air pressure to pump, or
increase air to gun at gun fitting
and/or regulator.
Turn fluid knob in on gun. See
Spray Techniques in Operation
Manual 309915.
