Apply Fluid

The gun does not have an air shutoff. The air should be activated before the fluid to ensure full atomization of fluid and prevent buildup on the air cap.

Adjust the system control device, if it is auto- matic, so the gun starts spraying just before meeting the part and stops as soon as the part has passed.

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 sur- face to be sprayed with 50% overlap.
