Cleaning
Proper cleaning is the best way to ensure
trouble free performance from your
spray gun. If your gun is not thoroughly
cleaned, damage and poor spraying will
result. Problems caused by improper
cleaning will not be covered by the war-
ranty. Clean the spray gun immediately
after each use.
To clean your spray gun:
1. Spray a small amount of solvent
through the spray gun.
Note: Check with local laws
regarding this practice. If you are
spraying on a regular basis, spraying
solvents into the air may be illegal. A
cabinet style spray gun cleaner may
be required.
2. DISCONNECT SPRAY GUN FROM AIR!
3. Unscrew the cup.
4. Disassemble the gun by unscrewing
the fluid control knob, removing the
spring and needle (
Figure 13).
5. Unscrew the atomizing cap with
your fingers and the fluid tip with
the service wrench. The fully
disassembled gun should look like
Figure 13.
6. Rinse these parts thoroughly in
solvent then dry with compressed air
or let air dry.
Note: If the small holes in the
atomizing cap become blocked, soak
in cleaning solvent. If the blockage
still exists, clear the blockage with
a small needle, taking great care
to not enlarge or damage the hole.
Damage to the hole will create a
disrupted spray pattern.
7. Use the cleaning brush with solvent
to clean the inner orifice and other
hard to reach areas on the outside of
the spray gun body.
8. Wipe the rest of the gun body with a
shop towel and dry.
NOTICE
DO NOT soak the spray gun body in
solvent. Prolonged exposure to solvent
will rapidly deteriorate the spray gun
washers and seals. Ignoring this notice
will void your warranty.
EXPLOSION HAZARD! Chlorinated
Solvents like Tricloroethane and
Methylene Chloride (methyl chloride)
can chemically react with aluminum
and may explode. Many parts in spray
guns are made of aluminum. Read
solvent label carefully before using
solvent.
