Fluttering or spitting spray. Insufficient fluid supply. Adjust fluid regulator or fill fluid supply tank.
Air in paint supply line. Check, tighten pump siphon hose connec-
tions, bleed air from paint line.
Attempting to “feather” (partially
trigger the gun). Cannot “feather” with an AA gun. Feather will
cause drastic reduction of pressure at the tip,
resulting in poor atomization and/or spitting.
Striping spray. Spray tip partially plugged. Clean or replace spray tip. See page 14.
Irregular pattern. Fluid build-up on spray tip, or
spray tip partially plugged. Clean or replace spray tip. See page 14.
On defective side of pattern, air
horn holes are partially or totally
plugged.
Clean air horn holes with solvent and soft
brush. See page 14.
Pattern pushed to one side,
same side of air cap gets dirty. Air horn holes partially or totally
plugged. Clean air horn holes with solvent and soft
brush or toothpick. See page 14.
Material build up on air cap. Air pressure setting too high. Reduce inlet air pressure. Seven to 10 psi
(4.9 to 7.0 kPa, 0.49 to 0.7 bar) air pressure
when triggered is recommended.
