Cause
Needle packing is too tight
Needle packing is too loose
1. Insufficient triggering air
2. Piston binding
1. Air pressure too high
2. Fluid flow too low
Dirty or damaged air
cap/holes
1. Air pressure is too low
2. Spray gun is too close to
working surface
3. Fluid flow is too high
1. Air cap dirty or damaged
2. Fluid tip dirty or damaged
1. Insufficient air pressure
2. Insufficient fluid flow
3. Fluid too heavy for current
setup
1. Damaged fluid tip
2. Loose fluid tip
3. Dried material in fluid tip/
needle
4. Fluid source empty/low
5. Needle packing too loose
1. Air pressure too high
2. Fluid adjustment too low
3. Spray too far from working
surface
AUTOMATIC
Solution
1. Remove triggering assembly
2. Insert screwdriver into rear of spray gun
3. Turn fluid seal nut counter-clockwise 1/4 turn (refer
to page 9 for packing adjustment)
4. Lubricate needle and reinstall
1. Remove triggering assembly
2. Insert screwdriver into rear of spray gun
3. Turn fluid seal nut clockwise 1/4 turn (refer to page
9 for packing adjustment)
4. Lubricate needle and reinstall
1. Increase triggering air pressure
Note: Do not exceed 50 psi
2. Remove triggering assembly. Remove trigger piston
and lubricate o-ring. Reinstall
1. Reduce atomizing air pressure
2. Turn fluid control knob counter-clockwise
Note: if fluid flow is still insufficient after adjusting,
replace fluid tip with next largest size
Clean air cap
Note: Do not use metal tools to clean air cap
Note: If problem persists after cleaning, replace air cap
1. Increase atomizing air pressure
2. Ensure proper distance from surface
is achieved, normally 6-10" from surface
3. Adjust fluid control knob clockwise to
decrease fluid flow
1. Clean air cap
Note: Do not use metal tools to clean air cap
2. Clean fluid tip
Note: If problem persists after cleaning replace
air cap or fluid tip
1. Check atomizing air and triggering air pressures
and increase if necessary
2. Adjust fluid control knob counter-clockwise to
increase fluid flow
3. Thin coating and/or change fluid tip to next largest
size
1. Remove and inspect for damage
2. Ensure fluid tip is tight
3. Flush with solvent
4. Check coating and refill if necessary
5. See solution: (coating leakage out of rear of gun)
1. Reduce atomizing air pressure
2. Adjust fluid control knob counter-clockwise until
desired results are achieved
3. Ensure proper distance from surface is achieved,
normally 6-10"
