POSSIbLE REASON FOR PRObLEM
SOLUTION
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.
Dissolve material in the side ports with thinner,
then blow the gun clean.
Do not poke into the opening with metal
instruments.
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.
Remove the air nozzle and wipe off fluid tip
using a rag dampened with thinner.
Tighten the 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.
Check supply pressure and reduce if over 50psi.
Adjust paint needle if required.
Check spray pattern on a test panel.
Dirt between the fluid nozzle seat and body or
loosely installed fluid nozzle will cause the gun to spit.
Remove the fluid nozzle, clean the back of the
nozzle and the nozzle seat in the gun body
using a rag dampened with thinner.
Replace the nozzle and secure it tightly against
the body.
Material bubbles
in paint cup.
Atomised air flowing through the paint channel to 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
damaged.
Tighten, clean or replace parts accordingly.
6. TROUbLESHOOTING
A faulty spray is usually caused 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 spray can be obtained.
