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 compli-
ant pressure shown on pages 3-4 to remain in
compliance.

• 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,
requirements.
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.
• 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.
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,
312414P 7
Setup
Adjust Spray Pattern
1. Rotate the air cap to achieve desired spray
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.

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.
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.
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
NOTICE
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.
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
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.
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 Com-
pliant Cleaning Methods, page 11.

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 informa-
tion on how to correct the problem.
• Follow the Pressure Relief Procedure,
• Clean the fluid and air line filters daily.
• Check for any fluid leakage from gun and fluid hoses.
NOTICE
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.
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 appli-
cable.
1. Follow Pressure Relief Procedure,
2. Disconnect the fluid supply hose and air supply hose from gun.
3. Connect the solvent supply hose to the gun.
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,
8. Disconnect the solvent supply hose from the gun.

Daily Gun Maintenance
Clean Gun
NOTICE
• 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.
2. Remove air cap. Trigger gun, remove nozzle, and soak both in a compatible solution.
NOTICE
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.
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
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.
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.
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.
