SPRAY PATTERN/PROBLEM POSSIBLE REASON
Will not spray
Fluid leakage from
packing nut.
Air leaking from air cap
without pulling trigger.
Thin, sandy, coarse
finish/excessive
overspray.
Thick, dimpled finish
resembling orange peel.
Low air pressure.
1)No air pressure at gun.
2)Fluid control screw
not open enough.
3)Material too heavy.
1)Dry packing.
2)Sluggish needle.
3)Tight packing nut.
4)Worn fluid nozzle or
needle.
1)Sticking air valve stem.
2)Residue on air valve
or seat.
3)Worn or damaged
air valve or seat.
4)Broken air valve spring.
5)Bent valve stem.
1)Gun held too far
from surface.
2)Atomization
pressure set too
high.
3)Improper gun
motion.
Gun held too close to
surface.
Regulator/compressor
settings.
1)Check air supply and air lines.
2)Open fluid control screw. Increase fluid
pressure at tank.
3)Thin material.

2) Lubricate.
3) Adjust.
4) Replace.
1)Lubricate.
2)Clean.
3)Replace.
4)Replace.
5)Replace.
1)Move gun closer to

pressure.
3)Move at moderate pace,
parallel to surface.
no arcing.
Move gun further from
surface.
Adjust the regulator on the tool to the
maximum setting. Adjust the compressor
regulator to tool maximum of 29 PSI.
NOTE: Air hoses may cause up to 15 PSI loss
in pressure, so you may need to set a higher
compressor output to maintain the required
pressure at the tool.
