Operation

Pressure Relief Procedure

1.Turn off the gun air supply.

2.Trigger the gun to relieve pressure.

Apply Fluid

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.

1.Fill the cup with material. Do not fill past the shoulder on cup.

2.Turn on the shop air to the gun. Set atomizing pressure with the gun fully triggered.

3.Adjust the pattern size and shape. See page 6.

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.

See Troubleshooting, page 10, if you

experience an irregular pattern.

Operation

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 9.

.

Clean air line filters as directed by the manufacturer.
