Problem
Cause
Solution
Normal pattern
No action necessary
Dirty or damaged air cap or fluid
nozzle.
Rotate air cap 180°.
If pattern follows air cap,
problem is in air cap. Clean
and inspect. If pattern is not corrected, replace air cap.
If pattern does not follow the air cap,
the problem is
with the fluid nozzle. Clean and inspect the nozzle. If
the pattern is not corrected, replace nozzle.
Pressure too high for viscosity of
material being sprayed.
a. Reduce air pressure.
b. Increase material viscosity
c. Correct pattern by narrowing fan size with spray
width adjustment knob.
Dirty or distorted air horn holes.
Rotate air cap 180°.
If pattern follows air cap,
problem is in air cap. Clean
and inspect. If pattern is not corrected, replace air cap.
Will not spray.
a. Cup is not tight
a. Tighten cup lid.
b. Cup empty.
c. Fill cup.
d. Air cap not seated.
e. Turn spray width adjustment knob fully counter-
clockwise. Tighten air cap.
a. Air pressure too low.
b. Gun held too close to surface.
a. Increase air pressure.
b. Hold gun about 6-8 inches (150-200 mm) from sur-
face.
