Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.
WARNING
WARNINGWARNINGWARNING
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:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request MSDS forms from distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and
cause serious injury.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
2 313385B
PLASTIC PARTS CLEANING SOLVENT HAZARD
Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many
solvents can degrade plastic parts and cause them to fail, which could cause serious injury or property
damage. See Technical Data in this and all other equipment instruction manuals. Read fluid and solvent
manufacturer’s warnings.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but is not limited to:
• Protective eye wear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing protection
NOTICE
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:
1. Remove material line from sprayer.
2. Tip sprayer to allow material (water) to flow out of pump inlet.
Before adding material or starting unit in cold weather, run warm water through pump.

Troubleshooting
Troubleshooting
Before performing any Troubleshooting procedures, follow Pressure Relief procedure on page 6.
PROBLEM CAUSE SOLUTION
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. Remove
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 Pressure,
page 6. Restart.
Contact an authorized Graco service
center.
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 maximum.
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 finger through
the surface of the material.
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

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
