Problems
Air enters between fluid nozzle and tapered
seat of spray gun body.
Air is drawn from fluid needle packing set.
Air enters at fluid container fitting nut or fluid
hose joint.
Paint buildup on air cap ASSY. partially
clogs horn holes.
Air pressure from both horns differs.
Paint buildup or damage on fluid nozzle
circumference and air cap ASSY. center.
Fluid nozzle is not properly fitted.
Paint viscosity too low.
Fluid output is too high.
Pattern air pressure is too high.
Paint viscosity is too high.
Fluid output is too low.
Fluid nozzle and fluid needle are not seated
properly.
The first-stage travel of trigger (when only air
discharges) decreases.
Paint buildup inside air cap ASSY.
Parts to be checked

2.
1. Add paint to increase viscosity.
Turn fluid adj. knob clockwise to reduce fluid output.
2.
3. Turn pattern adj. ASSY. clockwise to reduce pattern air pressure.
