Troubleshooting
Problem Cause Solution
Spray Pattern Normal pattern. No action necessary.
Spray Pattern Dirty or damaged air cap or
fluid nozzle.
Rotate air cap (5) 180°.
If pattern follows air cap, prob-
lem is in air cap. Clean and
inspect. If pattern is not cor-
rected, replace air cap.
If pattern does not follow the air
cap, the problem is with the
fluid nozzle (4). Clean and
inspect the nozzle. If the pat-
tern is not corrected, replace
nozzle.
Spray Pattern Fan pressure too high for vis-
cosity of material being
sprayed.
Reduce fan air pressure and
increase material viscosity.
Spray Pattern Dirty or distorted air horn
holes.
Clean and inspect air cap (5). If
pattern is not corrected,
replace air cap.
