Central Pneumatic 93305 Assembly And Operating Instructions Manual page 9

IMPORTANT: Before using for the first time, the spray gun must be cleaned
using a solvent based thinner. If not removed, the red oil used by the
manufacturer for testing and corrosion protection may contaminate paint.
IMPORTANT: The Spray Gun must be cleaned immediately after use.
Improper cleaning is a common reason for the Spray Gun not to work.
Pattern Adjustment
Warning!! Never exceed the Maximum Inlet PSI of 43 PSI.
1. Adjust the Gauge (38) pressure to 10-30 PSI using the Air Regulator (24). If you need
to reduce the air pressure for specific areas, adjust the Air Adjustment Knob (73).
2. To set the pattern size specific to the job, use the Pattern Control Knob (57) (see FIG-
URE 1 on page 6). By turning it counterclockwise (all the way open), the pattern will
flatten. Turn the Pattern Control Knob (57) clockwise for a round pattern.
See FIGURE 5 below.
3. Close the Fluid Control Knob (67) and fully open the Fluid Flow Knob (11). See FIGURE
1 on page 6.
4. After setting up a piece of scrap material, squeeze the Trigger (78) in short bursts while
turning the Fluid Control Knob (67) 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 Fluid Control Knob (67). If the spray appears too
thick (you see globs of paint), close down the Fluid Control Knob (67) slowly, checking
the mixture after each adjustment.
See FIGURE 6 below.
