Pressure Relief Procedure

WARNING

Follow Pressure Relief Procedure, page 13 when you stop spraying and before cleaning, checking, ser- vicing, or transporting equipment. Read warnings, page 3.

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.

1.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.

Applying the Fluid

When using the HVLP spray gun, instead of a conven- tional 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 what is produced by conven- tional airspray. Take care to avoid runs or sags as you spray.
