Spray Pattern

Normal pattern.

No action necessary.

Spray Pattern

Dirty or damaged air cap or 
fluid nozzle.

Rotate air cap (13) 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 (11). Clean and 
inspect the nozzle. If the pat-
tern is not corrected, replace 
nozzle.

Spray Pattern

Pressure too high for viscosity 
of material being sprayed.

Reduce air pressure and 
increase material viscosity.

Correct pattern by narrowing 
fan size with the fluid control 
valve (8).

Spray Pattern

Dirty or distorted air horn 
holes.

Clean and inspect air cap (13). 
If pattern is not corrected,
