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 warranty. 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 the gun from the com-
pressed air!
3. unscrew the cup.
4. disassemble the gun by unscrewing
the fluid control knob, removing the
spring and needle.
5. unscrew the atomizing cap with your
fingers and the fluid tip with the service
wrench. the fully disassembled gun
should look like
figure 14.
6. rinse these parts thoroughly in sol-
vent, then dry with compressed air or
let air dry.
note: If the small holes in the atomiz-
ing cap become blocked, soak in clean
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 sol-
vent will rapidly deteriorate the spray
gun washers and seals. ignoring this
notice will void your warranty.
eXplosion hazard! chlorinated
solvents like 1,1,1-tricloroethane
and methylene chloride (methyl
chloride) can chemically react with
aluminum and may explode. many
parts in spray guns are made of alu-
minum. read solvent label carefully
before using solvent.
