2. Fluid nozzle is dirty or worn.
1. Clean or replace air cap.
2. Clean or replace fluid nozzle.
1. Regulate paint viscosity.
2. Reduce air pressure.
Width of spray
pattern is too narrow
1. Paint is too thick.
2. Atomization air pressure is too low.
1. Regulate paint viscosity.
2. Increase air pressure.
Air leakage from air
cap when trigger is
