cleaninG The Gun
8.1.1.
Flush the gun through with clean solvent.
8.1.2.
Use a bristle brush and solvent to wash off accumulated paint.
Clean the air nozzle using a brush. Blow clean with air. Handle all nozzles carefully and do noT make any alterations in the gun.
8.1.3.
8.1.4.
Wipe the outside of the gun with a dampened solvent rag.
8.1.5.
If there is a need to probe the holes in the nozzles, ensure a tool that is softer than brass is utilised, under no circumstances use a
metal tool, as the slightest amount of damage will adversely affect the spray pattern.
8.1.6.
Adjust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.
9. mainTenance
9.1.1.
Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check
that it is the correct part, or unscrew it, realign and retry. do noT use excessive force when re-assembling.
9.1.2.
When changing the nozzle size, ensure the complete nozzle set is fitted. This consists of air cap, fluid nozzle and paint needle.
Insert the fluid nozzle before paint needle.
10. 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. This 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.
Problem
Paint spray flutter
Material bubbles or "boils" in paint cup.

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.
