Pattern Adjustment
Warning!! Never exceed the Maxi-
mum Inlet PSI of 115 PSI.
1. If you need to reduce the air pressure
for specific areas, adjust the pressure
regulator of the air compressor.
2. To set the pattern size specific to the
job, use the Pattern Control Knob
(10) ( see FIG. 1). By turning it coun-
terclockwise (all the way open), the
pattern will flatten. Turn the Pattern
Control Knob (10) clockwise for a
round pattern. (See FIG. 4 below.)
1. Turn the Needle Adjusting Screw (16)
clockwise until it is fully closed. ( See
FIG. 1.)
2. After setting up a piece of scrap ma-
terial, squeeze the Trigger (7) in short
bursts while turning the Needle Ad-
justing Screw (16) counterclockwise
and observe the spray patterns until
you see the pattern you want. Also,
look at the pattern for consistency.
Too much air may cause the spray
to come out too fine. Reduce the
air pressure or allow more material
to come out by opening the Needle
Adjusting Screw (16). If the spray
appears too thick (you see globs of
paint), close down the Needle Adjust-
ing Screw (16) slowly, checking the
mixture after each adjustment. ( See
FIG. 5 below.)
