Operation
311052H 13
For a narrower pattern, supply air to the gun fan air inlet
(or open the fan adjustment valve on manifold 288223).
The tip size is the primary controller of the pattern size.
Use the fan air only as needed to slightly adjust the pat-
tern size.
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.
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 F
