6. For fine pattern adjustment, turn air
flow control knob clockwise to de-
crease and counterclockwise to in-
crease air flow (See Figure 9).

NOTE: Reducing air flow will reduce
overspray.
Air from the turbine

can be used to blow
dry areas too heavily coated or slow in
drying.
Air from the turbine is warm as a result
of normal operation. Finish quality can
be affected on hot, dry days due to
premature drying of some coatings such
as lacquer. Add retarding agents to the
materials to avoid premature dying.
Consult material supplier for proper
retarding agent and mixing procedures.

CLEANING

Make sure working
area is well
ventilated when using solvents. Dispose
of all materials properly in accordance
with all local regulations
1. Remove material control knob, spring
and needle. (Pull trigger to help
remove the needle).
Removing the

needle prior to
removing the nozzle will prevent
needle damage.
2. Unscrew and remove retaining ring,
air cap and air flow ring. Use supplied

3. Place the parts and the paint cup in a
bucket or other suitable container.
Soak in an appropriate solvent, or in
soap and water if latex was used . To
clean the gun, pour solvent through
material tube until the solution clears
(See Figure 11).

5. Repeat cleaning procedure from the
nozzle end of the gun.
6. When the gun and all parts are
thoroughly cleaned, use turbine hose

to dry the parts and blow fun
passages dry. Thorough drying before
reassembly prevents coating
contamination during the next
operation of the unit and inhibits
oxidation of internal gun
components.
7. Reinstall the components in reverse
order of disassembly. Always install
nozzle before installing the needle to
prevent needle damage.
6. When the gun and all parts are
thoroughly cleaned, use the turbine
hose to dry the parts and blow the
passages dry. Thorough drying of the
gun and all components prior to
reassembly prevents coating contami-
nation during the next operation of
the unit, and inhibits oxidation of
internal gun components.
The four raised
