Air Flow Adjustment Preventing Material
Surge at Gun Trigger
For Continuous
Spraying
• For a lighter spray pattern,
decrease material pressure at
sprayer.
• For a heavier spray pattern,
increase material pressure at
sprayer.
• Trigger gun.
• To decrease air flow, close air valve
(A) (clockwise).
• To increase air flow, open air valve
(A) (counter-clockwise).
NOTE: Keep a small amount of air
flowing through air line and gun tip to
prevent material from backing up needle
Pressure will build up in system when
you stop triggering gun. To prevent
material surge at beginning of spray
pattern,
• when you first pull trigger, point
gun away from surface you are
spraying.
• hold gun away from surface and
gradually work your way closer to it.
• trigger gun as little as possible
• Engage trigger lock (D) to hold
trigger open and reduce fatigue.
Compressor Power
Pack Performance
• .Reduce engine RPM (throttle).
Running the engine slower will
reduce pressure surging, heat
and noise.
• The pressure unloader, unloads
less frequently, if the engine
RPM (throttle) is set lower.
