TROUBLESHOOTING

CAUSE
Horn holes plugged.
Obstruction on top or bottom of fluid tip.
Cap and/or tip seat dirty.
Left or right side horn holes plugged.
Dirt on left or right side of fluid tip.
Remedies for the top-heavy, bottom-heavy, right-heavy, and left-heavy patterns:
1. Determine if the obstruction is on the air cap or the fluid tip. Do this by making a test
spray pattern. Then, rotate the cap one-half turn and spray another pattern. If the defect
is inverted, obstruction is on the air cap. Clean the air cap as previously instructed.
2. If the defect is not inverted, it is on the fluid tip. Check for a fine burr on the edge of the
fluid tip. Remove with #600 wet or dry sand paper.
3. Check for dried paint just inside the opening; remove by washing with solvent.
