Pattern Adjustment
WARNING! Do not exceed the Operat-
ing Air Pressure shown on the
Specication chart.
1. Adjust the air pressure during opera-
tion with the Trigger fully depressed.
If you need to reduce the air pressure
for specic areas, adjust the air sup-
ply pressure.

Figure 2
Flat/Open
Round/Closed
Use the Pattern Control Knob to ad-
just the spray pattern. Turn the Pat-
tern Control Knob counterclockwise
(all the way open) to atten the spray
pattern. Turn it Clockwise for a round
spray pattern - see Figure 2.
3. Turn the Fluid Control Knob clock-
wise until it is fully closed.
4. After setting up a piece of scrap
material, squeeze the Trigger in short
bursts while tuning the Fluid Control
Knob counterclockwise and observe
the spray patterns until you see the
pattern you want.

Correct
Also, look at the pattern for consis-
tency - see above. Too much air
may cause the spray to come out
too ne. Reduce the air pressure or
allow more material to come out by
opening the Fluid Control Knob. If
the spray appears too thick (you see
globs of paint), close down the Fluid
Control Knob slowly, checking the
mixture after each adjustment.
Work Piece and Work Area Set Up
1. Designate a work area that is clean
and well-lit. The work area must not
allow access by children or pets to
prevent injury and distraction.
2. Route the air hose along a safe route
to reach the work area without creat-
ing a tripping hazard or exposing the
air hose to possible damage. The air
hose must be long enough to reach
the work area with enough extra
length to allow free movement while
working.
IMPORTANT: Clean the Spray Gun IMMEDIATELY after use.
Improper cleaning will cause the Spray Gun not to work.
