• An appropriate solvent
• Solvent safety container (grounded)
• Small soft-bristled brush
For efficient electrostatic operation, keep the
gun’s exterior and low voltage / high voltage
cable free of paint accumulation. This prevents
the loss of voltage to ground with a resultant re-
duction in transfer efficiency.
> Before cleaning the nozzle assembly,
turn the control unit OFF OFF OFF OFF OFF and flush the
fluid line with a compatible solvent until
clean. Turn the paint and air supplies
OFF
OFF OFF OFF OFF. Trigger the gun to relieve both fluid
and air pressures.

surface charge may build up on the plastic
surface and discharge to the nearest

> Ensure supply pressures have been
bled to zero prior to servicing the gun.
Failure to do so may cause personal injury.
> If the fluid nozzle is completely clogged,
triggering the gun will not release the
pressure. Cover the end of the gun with a
heavy rag and loosen the nozzle nut slowly
into a grounded catch container.
> Any broken or damaged components
should be replaced. Any damage to the
gun may result in UNSAFE

1. Turn OFF the control unit power. Turn
OFF supply air to the AVIATOR power
generator.
2. Turn the paint and air supplies OFF.
Relieve both fluid and air pressures.
Set the trigger stop lever.
> A wire brush or metal tools must
NEVER NEVER NEVER NEVER NEVER be used. NEVER NEVER NEVER NEVER NEVER use a cleaning
tool that is harder than the plastic parts. If
a deposit cannot be removed with solvent
and a rag or the soft brush, soak the part in
solvent ONLY
ONLY ONLY ONLY ONLY until the deposit can be
removed! NEVER NEVER NEVER NEVER NEVER soak the gun body,
barrel, or hook transformer!

3. Unscrew the nozzle nut completely from
the barrel.
4. With the front of the barrel tilted down-
ward, remove the air and fluid nozzles.
5. Clean all parts in a suitable solvent and
examine for wear and damage. To clear
the fluid nozzle orifice, blow compressed
air through the tip in the opposite direc-
tion of flow. Soaking in solvent and/or
brushing may also be necessary to
clean the orifice. Replace as neces-
sary.
6. Clean all exterior surfaces of the gun
with a rag and a suitable solvent.
7. Assemble the parts in reverse order of
disassembly.
