Gun Selection
312579H 5
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 pres-
sure must remain under 35 psi (0.24 MPa,
2.4 bar) to remain in compliance.
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

Setup
6312579H
Setup
1. Shut off the air supply.
2. Install a shutoff valve (not supplied) down-
stream of the air regulator to shut off gun
air.
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 FIG. 1.
5. Connect the fluid supply to the fluid inlet
fitting.
Ground the Gun
Check your local electrical code for detailed
grounding instructions.
Ground the gun through connection to a
Graco-approved conductive 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 sol-
vent before using the equipment. See Flush,
page 9.
• Check that your shop air provides
adequate air flow. See Technical
Data, page 20, for minimum cfm
requirements.
• Recommended 5/16 in. (7.9 mm) ID
hose, optional 3/8 in. (10 mm) ID air
hose.
• Set shop air pressure regulator (not
supplied) according to paint manu-
facturer’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. If an air adjusting valve is
desired, use a Graco adjustable air
valve (234784).

Setup
312579H 7
Adjust Spray Pattern
1. Rotate the air cap to achieve desired spray
pattern. See FIG. 2.
2. To achieve full fan pattern, open the air
control valve by turning the knob fully coun-
terclockwise. 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 20, for inlet
air pressure.
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.
6. To reduce fluid flow, turn the fluid control
valve clockwise.
7. Spray a test pattern. Evaluate the spray
pattern size and atomization.
8. To achieve a narrow spray pattern, turn air
control valve clockwise.
9. 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.

• If the fluid control valve is turned clock-
wise all the way, the gun will emit only
air.
• If you cannot achieve the correct fluid
flow with the fluid control valve, a differ-
ent 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.

Operation
8312579H
Operation
Pressure Relief Procedure
1. Turn off the gun air supply.
2. Trigger the gun to relieve pressure.
Apply Fluid
1. Fill the cup with material. Do not fill past the
full markings on cup.
2. Turn on the shop air to the gun. Set atomiz-
ing pressure with the gun fully triggered.
3. Adjust the pattern size and shape. See
page 7.
4. To achieve the best results when applying
fluid:
• Keep the gun perpendicular and
6 to 8 inches (150 to 200 mm) from the
object being sprayed.
• Use smooth, parallel strokes across the
surface to be sprayed with 50% overlap.
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 pro-
duced 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 10.
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 11, if you
experience an irregular pattern.
Clean air line filters as directed by the
manufacturer.

Daily Gun Maintenance
312579H 9
Daily Gun Maintenance
General Tasks
Follow the Pressure Relief Procedure,
page 8.
• 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 11, for information
on how to correct the problem.
• Clean the fluid and air line filters daily.
• 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 with the fluid that will be
sprayed.
1. Follow Pressure Relief Procedure,
page 8.
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. Follow Pressure Relief Procedure,
page 8.
Clean Gun and Cup
1. Flush, page 9.
2. Dampen a soft cloth with solvent and wring
out the excess. Point the gun down and
wipe off the outside of the gun and cup.
3. Make sure cup lid vent hole is clear.
4. Blow dry gun inside and out. Lubricate.
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.
See Compliant Cleaning Methods,
page 10, 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 10, to comply with air quality laws if
applicable.

Daily Gun Maintenance
10 312579H
Clean Nozzle and Air Cap
1. Remove air cap (13), trigger gun, remove
nozzle (11), and soak both in a compatible
cleaning solution.
2. Clean air cap, nozzle, and front of the gun
with a soft-bristle brush dipped into com-
patible 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.
4. 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.
5. Install the retaining ring (14) and
air cap (13).
6. After cleaning the gun, lubricate the follow-
ing 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 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.
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.
When reassembling, make sure the
air cap matches the color etched onto
the side of the nozzle (gold, brown, grey,
blue, etc.).
