FIG. 11: Correct Spray Pattern

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 assure 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 work piece and stops as soon as the work piece has passed. Keep the gun a consistent distance, 8 to 10 inches (200 to 250 mm), from the surface of the object being sprayed.

Operation

To achieve best results when applying fluid:

Keep gun perpendicular and 8 to 10 inches (200 to 250mm) from object being sprayed.

Use smooth, parallel strokes across surface to be sprayed with 50% overlap. See FIG. 12.
