6.2.
Air nozzle, fluid nozzle and needle assembly
6.2.1.
To clean the nozzles, soak them in solvent to
dissolve any dried material then blow them clean
with air. Handle all nozzles carefully and do
not make any alterations in the gun.
6.2.2.
If you need to probe the holes in the nozzles, be
sure to use a tool that is softer than brass; do not
use metal instruments.
6.2.3.
Adjust the fluid needle valve so that when the
gun is triggered, air flow occurs before fluid flow.
6.3.
Maintenance
6.3.1.
Disassemble using the supplied spanner. (fig.7)
6.3.2.
Take care when re-assembling. Firstly screw
parts hand tight to avoid cross-threading then
tighten with spanner. If a part cannot easily be
turned by hand, check that you have the correct
part, or unscrew, realign and try again. DO NOT
use excessive force when re-assembling.
6.3.3.
Lubricate the gun daily with a light machine oil.
6.3.4.
If you change the nozzle size, ensure the
complete nozzle set is exchanged. Insert paint
nozzle before putting the paint needle in.
7. TROUBLE SHOOTING
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 will cause a faulty spray. If either the air nozzle or fluid nozzle is damaged, these parts must be replaced before
a perfect spray can be achieved.

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 atomising 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.
Dirt between the fluid nozzle seat and body or loosely
installed fluid nozzle will cause the gun to spit.
Atomised air flowing through the paint channel to pot.
The paint nozzle is not tight enough. Air nozzle is not
completely screwed in.

Original Language Version
Dissolve material in the side ports with solvent, then
blow the gun clean. Do not poke into the opening 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.
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.
Tighten, clean or replace parts accordingly.
