Operation

Pressure Relief Procedure

1.Turn off all bleed type air valves and all other air and fluid supplies to the gun.

2.Trigger the gun into a grounded metal waste con- tainer to relieve air and fluid pressure.

Apply Fluid

The spray gun has a built-in lead and lag operation. When triggered, the gun begins emitting air before the fluid is discharged. When the trigger actuation air is stopped, the fluid stops before the air flow stops. This helps ensure that the spray is atomized and prevents fluid buildup on the air cap and tip.

Adjust the system control device, if it is automatic, so the gun starts spraying just before meeting the part and stops as soon as the part has passed. Keep the gun a consistent distance, 6 to 8 in. (150 to 200 mm), from the surface of the object being sprayed.

Operation

To achieve best results when applying fluid:

•Keep gun perpendicular and 6 to 8 in. (150 to 200 mm) from object being sprayed.

•Use smooth, parallel strokes across surface to be sprayed with 50% overlap.
