Operating Instructions and Parts Manual

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

wrench to remove nozzle. The spring

does not have to be removed.

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).

4. Use cleaning brush (saturated with

solvent) to clean material tube and

nozzle (See Figure 12).

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

knobs on the air

flow ring must be facing forward when

assembled.
