MAINTENANCE
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 warranty. Clean the
spray gun immediately after each use.
To clean your spray gun:
1. Empty the cup and spray a small
amount of solvent through the gun.
Note: 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. Remove the cup and cup lid.
4. Disassemble the gun by unscrewing
the fluid control knob then remove the
spring and needle.
5. Unscrew the atomizing cap and the
fluid tip. The fully disassembled gun
should look like Figure 14.
6. Rinse all parts thoroughly in solvent,
then dry with compressed air or let
air dry. Try not to expose O-rings to
solvent or they may get damaged.
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 gun body with a lint free shop
towel to 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 chem-
ically react with aluminum spray gun
parts and explode. Read solvent
label carefully to avoid using solvent
with these chemicals.
