Warnings
312101E 3
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
symbols refer to procedure-specific risks. Refer back to these warnings. Additional, product-
specific warnings may be found throughout the body 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:
• 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 lights on or off when flammable fumes
are present.
• Ground all equipment in the work area. See Grounding instructions.
• 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.
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.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• 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.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your Graco distributor for
information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and
hot surfaces.
• Do not kink or overbend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.

Setup
4312101E
Setup
1. Shut off the air supply.
2. Connect a clean, dry, filtered air supply to
the air inlet fitting (25). See page 10.
3. If this is the first time using the equipment,
flush the gun. See page 5.
Operation
Pressure Relief Procedure
1. Turn off the gun air supply.
2. Trigger the gun to relieve pressure.
Spraying
1. Fill the cup with material. Do not fill past the
full markings on cup.
2. Turn on the shop air to the gun and set
atomizing pressure with the gun fully
triggered.
3. Adjust the pattern size and shape with the
fluid adjust knob (8). Fluid adjust knob (8)
is factory set for maximum needle trigger
travel and material flow. Turn knob
clockwise to reduce pattern size/ fluid
flow and counterclockwise to increase it.
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 eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing protection
WARNING
• Check that your shop air provides
adequate air flow.
• Use a minimum 3/8 in. (10 mm) ID air
hose.
• Set shop air pressure regulator (not
supplied) according to paint manu-
facturer’s recommendation. See
maximum pressures and compliant
air pressures on page 2.
• Make sure no air restrictions, such as
low-volume cheater-valves, obstruct
the air flow. If an air adjusting valve is
desired, use a Graco adjustable air
valve (288744 or 234387) or Digi-tell
(288652).
• Install a shutoff valve (not supplied)
downstream of the air regulator to
shut off gun air.
• Install an inline air filter (not supplied)
to clean and dry the gun air supply.
CAUTION
Excessive atomizing air pressure can
increase over-spray, reduce transfer
efficiency, and result in a poor quality finish.
Regulatory agencies in certain states prohibit
the operation of a spray gun above 10 psi (69
kPa, 0.7 bar) atomizing air cap pressure.
See Troubleshooting, page 7, if you
experience an irregular pattern.

Maintenance
312101E 5
Volatile Organic Compounds
(VOC) Regulation
In certain states, spraying solvents that release
VOCs into the atmosphere when cleaning a
spray gun is prohibited. To comply with these
air quality laws, you must use a cleaning
method that prevents the escape of VOC
vapors into the atmosphere. See Compliant
Cleaning Methods, page 6.
Maintenance
• Frequently lubricate the gun moving
parts with a drop of non-silicone oil.
• Do not disassemble the spray gun if you
are having a spray pattern problem. See
Troubleshooting, page 7, for information
on how to correct the problem.
• Check for fluid leakage. Tighten fittings
or replace equipment as needed.
Flush
Flush before using the equipment, before
changing colors, and when you are done
spraying. Use solvent that is compatible with
gun wetted parts and fluid that will be sprayed.
1. Relieve pressure, page 4.
2. Dispose of any paint in the cup.
3. Fill the cup with a small amount of solvent.
4. Spray into a grounded metal waste
container until the equipment is clean.
5. Relieve pressure, page 4.
Cleaning Gun and Cup
1. Flush, page 5.
2. Use a rag moistened in solvent to wipe
outside of gun and cup.
3. Make sure cup lid vent hole is clear.
4. Blow dry gun inside and out. Lubricate, see
Maintenance, page 5.
Cleaning Nozzle and Air Cap
1. Remove air cap (13), trigger gun, remove
nozzle (11), and soak both in a compatible
cleaning solution.
2. Clean them and the front of the gun with
a soft-bristle brush dipped into compatible
solvent. Do not use a wire brush or metal
tools.
3. Use a soft implement, such as a toothpick
to clean out air cap holes.
Clean air line filters as directed by the
manufacturer.
See Compliant Cleaning Methods, page 6,
to comply with air quality laws if applicable.
CAUTION
• Do not submerge gun in solvent. Solvent
dissolves lubricant, dries out packings,
and clogs air passages.
• Do not use metal tools to clean air cap
holes as this may scratch them and distort
the spray pattern.
• Use a compatible solvent.
See Compliant Cleaning Methods, page 6,
to comply with air quality laws if applicable.
When reassembling, make sure the
air cap matches the color etched onto
the side of the nozzle (gold, brown, grey,
blue, etc.).

Repair
6312101E
Compliant Cleaning Methods
1. Place spray gun in a gun washer that com-
pletely encloses the gun and components
during cleaning, rinsing, and draining.
2. Spray solvent through the spray gun into
a closed gun cleaning station.

Troubleshooting
312101E 7
Troubleshooting
Problem Cause Solution
Normal pattern. No action necessary.
Dirty or damaged air cap or fluid
nozzle. Rotate air cap 180°.
If pattern follows air cap, problem is in air
cap (13). Clean and inspect. If pattern is
not corrected, replace air cap.
If pattern does not follow the air cap, the
problem is with the fluid nozzle. Clean
and inspect the nozzle. If the pattern is
not corrected, replace nozzle.
Pressure too high for viscosity of
material being sprayed.
Reduce air pressure and increase mate-
rial viscosity.
Correct pattern by narrowing fan size with
spray width adjustment knob (8).
Dirty or distorted air horn holes. Clean and inspect air cap. If pattern is not
corrected, replace air cap.
Gun spitting Air getting into paint stream. Check if cup is empty and fill.
Tighten fluid nozzle (11).
Check and tighten needle packing nut (17).
Check fluid nozzle (11) for damage.
Will not spray Cup is empty. Fill cup.
Fluid adjustment knob (8) turned
too far clockwise.
Adjust knob (8) counterclockwise.
Excessive air
blowing back Loose fluid nozzle (11). Tighten fluid nozzle (11).
Damaged fluid nozzle seal (21). Replace seal (21).
