Spray Pattern Troubleshooting
NOTE: Some spray pattern problems arecaused by the improper balance between air and fluid.
Problem Cause Solution
Air flow too high. Use gun atomizing air adjustment
valve to reduce air flow.
Spray tip worn. Replace tip.
Diffuser worn. Replace diffuser.
Sprayis too forceful (high velocity).
Fluid flow too high. Use smaller tip or lower pressure
Air flow too low. Use gun atomizing air adjustment
valvetoincreaseairflow.
Spray gun spitting.
Tip size is too large. Use smaller tip.
Paint notproperly filtered. Cleanor replace the gun filter.
Install inline filteror clean/replace
inline filter.
Tip clogging.
Tip size is too small. Uselarger tip.
Tip is clogged. See “Tip clogging,” above.
Distorted spray pattern (heavy to
one side). Spray tip worn ordamaged. Replacetip.
