How to use the air–assisted airless
spray gun.
With an air-assisted airless spray gun, the spray tip
shapes the fluid into a fan pattern. Air from the air cap
further atomizes the fluid and completes the atomiza-
tion of the paint tails into the pattern to produce a more
uniform pattern.
The spray gun has a built-in lead and lag operation. When
triggered, the gun emits air before the fluid is discharged.
When the trigger is released, the fluid stops before the air
flow stops. This helps assure the spray is atomized and
prevents fluid buildup on the air cap.
NOTE: The gun air and fluid inlets have 1/4–18 npsm
(R1/4–19) compound male threads that are compatible
with NPSM and BSP female swivel connectors.
1. Use the fan pattern valve (E) can be used to
reduce the pattern by about 25% of the total pat-
tern width. As the valve is opened, the pattern will
reduce slightly. The tip used designates the total
width of the spray pattern.
2. To unlock the gun trigger safety, turn the safety so
it is parallel with the trigger. To lock the gun trigger
safety, turn the safety to a right angle with the trig-
ger. See Fig. 3.

How to change the spray pattern
direction.
1. Relieve the air and fluid pressure.
2. Install a spray tip in the gun. Rotate the air cap
(the spray tip rotates with it) to determine the
direction of the spray pattern. See Fig. 4.
