Adjusting the Spray Pattern
1. To achieve full fan pattern, open the pattern adjust-
ment valve (25) by turning the knob fully counter-
clockwise.
2. Trigger gun and adjust gun air pressure:
3. To establish the correct fluid flow, turn the fluid
adjustment knob (21) counterclockwise until no
restriction of the trigger movement is felt, then turn
out another half turn. When the knob is turned far
enough, the trigger should be able to touch the gun
handle when the gun is triggered.
4. Pressure feed only: Adjust fluid pressure to achieve
desired fluid flow rate
5. To reduce fluid flow, turn the fluid adjustment knob
(21) clockwise.
6. Spray a test pattern. Evaluate the spray pattern size
and atomization.

• If the fluid adjustment knob is turned clockwise
all the way, the gun will emit only air.
• If you cannot achieve the correct fluid flow with
the fluid adjustment knob, a different sized noz-
zle may be necessary. For smaller fluid flow,
use the next size smaller nozzle. For a larger
fluid flow, use the next size larger nozzle.
