7. TRouBlEShooTInG
A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. If cleaning is required,
remove these parts and soak them in solvent. T his will soften the dried material which can then be removed with a brush or a cloth.
These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle are damaged, they
must be replaced before a perfect spray can be obtained.

Possible Causes
dried material in a side port restricts passage
of air. greater flow of air from the clean 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.
Material too thin or atomization air pressure
too high.
not enough paint in bottle.
nozzle set / seating dirty, damaged or loosely
installed.
Atomised air flowing through the paint channel
to the bottle. The paint nozzle is not
sufficiently tight.
Air nozzle is not completely screwed on

dissolve material in the side ports with
solvent, then blow the gun clean. do not poke
into the nozzles with metal instruments.
Remove the air nozzle and wipe off fluid tip
using a rag dampened with solvent. Tighten
the air nozzle.
Regulate material viscosity or reduce air
pressure.
Refill bottle. Remove the fluid nozzle, clean
the back of the nozzle and the nozzle seat
using a cloth dampened with thinner. Refit the
nozzle and secure it tightly against the body.
If necessary replace nozzle set.
Tighten, clean or replace parts accordingly.
