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 th e gun f rom the air
supply!
3. Unscrew the cup.
4. Use a wrenc h to loosen the air flow

the spring, and needle.

vent then dry wit h compresse d air or
let air dry.
Note: If the small holes in the atomiz-
ing cap become blocked, soak in clean
solvent. If th e blockage still exists,
clear the blockage with a small needle,
taking great care to not enlarge o r
damage the hole. Da mage to the hol e
