Problem Cause Correction
*Remedies for the top, bottom,
right, left heavy patterns are:
1. Determine if the obstruction is on
the air cap or fluid tip. Do this by
making a solid 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 paint by washing
with solvent.
