Remedies for the top-heavy, bottom-heavy, right-heavy and left-heavy patterns.
Determine if the obstruction is on the air cap or the uid tip. Do this by making a test spray pattern. Then, rotate the air cap and tip 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. Also check for
dried paint just inside the cap center hole opening, remove by washing with solvent.
If the defect is not inverted, it is on the uid tip. Clean tip. If problem persists, renew tip.
Heavy center pattern. Pattern adjustment valve set too low. Turn out counter clockwise to achieve correct
pattern.
Too much material. Reduce uid pressure.
Material too thick. Thin to correct consistency.
Atomizing air pressure too low. Increase air pressure.
Intermittent or 'uttering' spray fan. Fluid tip not seated correctly in gun
head.
Remove uid tip, clean components, check
cone seating on tip and gun for damage or
contamination.
Partially obstructed uid passage or
hose.
Clean or replace.
