Gun Selection
Conventional Guns
Excellent atomization and high production
rates typically with some reduction in transfer
efficiency.
HVLP Guns
An HVLP gun is a high transfer efficiency gun
which limits the air pressure at the air cap to
10 psi (0.07 MPa, 0.7 bar) maximum. In some
areas, an HVLP gun is required for compliance
with environmental standards.
Compliant Guns
A compliant gun is a high transfer efficiency
gun which has been tested to have a transfer
efficiency greater than or equal to HVLP guns.
The Graco compliant guns have no restrictions
on air cap pressures, but the gun inlet pressure must remain under the maximum compliant pressure shown on pages 3-4 to remain in
compliance.
6 312414J
Setup
At least one hose must provide a static
ground to the gun.
Connect Air and Fluid Lines
1. Shut off the air supply.
2. Install a shutoff valve (not supplied) downstream of the air regulator to shut off gun
air.
Setup
5. Connect a fluid hose to the fluid inlet fitting.
See FIG. 1.

3. Install an inline air filter (not supplied) to
clean and dry the gun air supply.
4. Connect a clean, dry, filtered air supply to
the air inlet fitting. See F
• Recommended 5/16 in. (7.9 mm) ID
hose, optional 3/8 in. (9.5 mm) ID hose.
• Check that your shop air provides adequate air flow. See Technical Data,
page 23, for minimum cfm
requirements.
• Set shop air pressure regulator (not
supplied) according to fluid manufacturer’s recommendation. See maximum
compliant air pressure on air cap.
• Make sure no air restrictions, such as
low-volume cheater valves, obstruct the
air flow.

Ground the Gun
Check your local electrical code and pump
manual for detailed grounding instructions.
Ground the spray gun through connection to a
Graco-approved grounded fluid or air supply
hose.
Flush Before Using Equipment
The equipment was tested with lightweight oil,
which is left in the fluid passages to protect
parts. To avoid contaminating your fluid with
oil, flush the equipment with a compatible solvent before using the equipment. See Flush,
page 10.
312414J 7
Setup
Adjust Spray Pattern
1. Rotate the air cap to achieve desired spray
pattern. See FIG. 2.
ti4839a
FIG. 2
2. To achieve full fan pattern, open the air
control valve by turning the knob fully counterclockwise. See FIG. 3.
3. To create a round pattern, turn the pattern
air off by turning the air control valve fully
clockwise. See FIG. 3.
4. Trigger gun and adjust gun air pressure.
Refer to Technical Data, page 23, for inlet
air pressure recommendations.
7. To reduce fluid flow, turn the fluid control
valve clockwise.
• If the fluid control valve is turned clockwise all the way, the gun will emit only
air.
• If you cannot achieve the correct fluid
flow with the fluid control valve, a different sized nozzle may be necessary. For
smaller fluid flow, use the next size
smaller nozzle. For a larger fluid flow,
use the next size larger nozzle.
8. Spray a test pattern. Evaluate the spray
pattern size and atomization.
9. To achieve a narrow spray pattern, turn air
control valve clockwise.
10.To improve atomization, reduce the fluid
flow rate. Increasing the air pressure can
improve atomization but may result in poor
Transfer Efficiency (TE) or non-compliant
operation.
5. To establish the correct fluid flow, turn the
fluid control valve counterclockwise until no
restriction of the trigger movement is felt,
then turn out another half turn.

Operation
Operation
Pressure Relief Procedure
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing or moving parts.
1. Turn off air and fluid supply.
2. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger the gun to
relieve pressure.
Apply Fluid
CAUTION
Excessive atomizing air pressure can
increase overspray, reduce transfer efficiency, and result in a poor quality finish.
Regulatory agencies in some states prohibit
the operation of a spray gun above 10 psi
(69 kPa, 0.7 bar) atomizing air cap pressure.
NOTE: See Troubleshooting, page 12, if
you experience an irregular pattern.
When using the HVLP spray gun, instead of a
conventional airspray gun, you may need to
use a slightly slower hand movement and
make fewer passes with the gun to coat a part.
This is due to the reduced spray velocity produced by lower HVLP air pressures, along with
a larger fluid particle size because there is less
air to blow off solvents than is produced by
conventional airspray. Take care to avoid runs
or sags as you spray.
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 11.
1. Turn on shop air and fluid supply to the
gun. Set atomizing pressure and fluid pressure with the gun fully triggered.
2. Adjust the pattern size and shape. See
page 8.
3. To achieve the best results when applying
fluid:
• Keep the gun perpendicular and
6 to 8 inches (150 to 200 mm) from object
being sprayed.
• Use smooth, parallel strokes across the
surface to be sprayed with 50% overlap.

Daily Gun Maintenance
Daily Gun Maintenance
Follow Pressure Relief Procedure, page 9,
when you stop spraying and before cleaning,
checking, servicing, or transporting equipment. Read Warnings, page 5.
General Tasks
• 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 12, for information
on how to correct the problem.
• Follow the Pressure Relief Procedure,
page 9.
Flush
Flush before changing colors, before fluid can
dry in the equipment, at the end of the day,
before storing, and before repairing equipment. Flush at the lowest pressure possible.
Check connectors for leaks and tighten as necessary. Flush with a fluid that is compatible
with the fluid being dispensed and the equipment wetted parts.
NOTE: See Compliant Cleaning Methods,
page 11, to comply with air quality laws if
applicable.
1. Follow Pressure Relief Procedure,
page 9.
2. Disconnect the fluid supply hose and air
supply hose from gun.
3. Connect the solvent supply hose to the
gun.
• Clean the fluid and air line filters daily.
• Check for any fluid leakage from gun and
fluid hoses.
CAUTION
Solvent left in gun air passages could result
in a poor quality paint finish. Do not use any
cleaning method that may allow solvent into
the gun air passages.
• Do not point gun up while cleaning it.
• Do not wipe gun with a cloth soaked in
solvent; wring out the excess.
• Do not immerse the gun in solvent.
4. Start the pump. Always use the lowest possible fluid pressure when flushing.
5. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger the gun until
clean solvent dispenses.
6. Turn off solvent supply.
7. Follow Pressure Relief Procedure,
page 9,
8. Disconnect the solvent supply hose from
the gun.
10 312414J
Daily Gun Maintenance
Clean Gun
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.
1. Flush, page 10.
2. Remove air cap. Trigger gun, remove nozzle, and soak both in a compatible solution.
CAUTION
Trigger the gun whenever you tighten or
remove the nozzle. This keeps the needle tip
away from the nozzle seating surface and
prevents the tip from being damaged.
3. Dip the end of a soft-bristle brush into a
compatible solvent. Do not continuously
soak the brush's bristles with solvent and
do not use a wire brush.
6. Trigger the gun while you install the fluid
nozzle with the gun tool. Tighten the nozzle
securely to 155-165 in-lb (17.5-18.6 N•m)
to obtain a good seal.
7. Install the retaining ring (14) and
air cap (13b).
8. Dampen a soft cloth with solvent and wring
out the excess. Point the gun down and
wipe off the outside of the gun.
9. After cleaning the gun, lubricate the following parts with lubricant 111265 daily:
• fluid control valve threads
• trigger pivot pin
• fluid needle shaft
Compliant Cleaning Methods
1. Place spray gun in a gun washer that completely encloses gun and components during cleaning, rinsing, and draining.
2. Spray solvent through the spray gun into a
closed gun cleaning station.
4. With the gun pointed down, clean the front
of the gun, using a soft-bristle brush and
solvent.
5. Scrub the air cap retaining ring, air cap,
and fluid nozzle with the soft-bristle brush.
• To clean out air cap holes, use a soft
implement, such as a toothpick, to
avoid damaging critical surfaces.
• Clean the air cap and fluid nozzle daily,
minimum. Some applications require
more frequent cleaning.
• Do not soak the air cap retaining ring in
solvent for prolonged periods of time.
