TROUBLESHOOTING
A faulty spray is usually cause by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. Soak these parts in a
solvent that will soften the dried material and remove with a brush or a cloth. Never use metal instruments to clean the air or fluid nozzles.
These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle is damaged, the
part must be replaced before a perfect spay can be obtained.

POSSIBLE REASON FOR PROBLEM
Dried material in a dirty side port restricts
passage of air. Greater flow of air from the
cleaner side port forces a fan pattern in the
direction of the clogged side.
Dried material around the outside of the fluid
nozzle tip restricts the passage of atomizing air at
one point through the centre opening of the air
nozzle and results in the pattern shown.
This pattern can also be caused by a loose air
nozzle.
A split spray or one that is heavy on each end of
a fan pattern and weak in the middle is usually
caused by too high an atomization air pressure or
by attempting to get too wide a spray with thin
material.
Dirt between the fluid nozzle seat and body or
loosely in stalled fluid nozzle will cause the gun to
spit.
pot.
The paint nozzle is not tight enough.
Air nozzle is not completely screwed in.
The air inlet seal is defective or nozzle insert is
