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. See page 4. 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. See page 4. If the
pattern is not corrected, replace nozzle.
Pressure too high for viscosity of material
being sprayed.
a. Reduce air pressure and increase fluid 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. See page 4. If pattern is not corrected, replace air
cap.
Will not spray. Fluid adjustment knob (16) turned too far
clockwise.
Adjust knob (16) to the counterclockwise.
a. Fluid pressure too high for viscosity of
material being sprayed.
a. Reduce fluid pressure.
b. Air pressure too low. b. Increase air pressure.
c. Gun held too close to surface. c. Hold gun about 6-8 inches (150-200 mm) from surface.
