Model H8116 Spray Gun -13-
SECTION 6: MAINTENANCE
Cleaning
Proper cleaning is the best way to ensure
trouble free performance from your spray
gun. If your gun is not thoroughly cleaned
between uses, damage and poor spraying
will result. Problems caused by improper
cleaning are not covered by the warranty.
Clean the spray gun immediately after
each use.
To clean your spray gun:
1. Spray a small amount of solvent or
reducer 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 air
supply!
3. Unscrew the cup.
4. Use a wrench to loosen the air flow
control knob, then remove the knob,
the spring, and needle.
5. Unscrew the atomizing cap with your
fingers and remove the fluid tip with
the service wrench. The fully disas-
sembled gun should look like Figure
10.
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.
