1. Flush the paint supply line and the applicator
paint passages using a solvent which is compat-
ible with the material being sprayed. Continue to
flush until all traces of paint are gone.

1. Check the entire system for damage, leaks and
paint accumulation.
2. Clean the atomizer assembly.
3. Conduct a current output test. See "Proced-
ures" in the "Maintenance" section.
2. Turn off the solvent supply, actuate paint
pushout air at color changer and trigger the appli-
cator. Allow all of the fluid to drain from the spray
applicator fluid passages.
3. Clean the exterior surfaces of the spray gun
with a solvent soaked rag. As long as the gun is
intact, a polar
polar polar polar polar solvent may be used for all clean-
ing, however, after cleaning, wipe off all surfaces
with a nonpolar
nonpolar nonpolar nonpolar nonpolar solvent to reduce conductive
residue on the applicator's surface. See "Polar
and Non-Polar Solvents" below regarding proper
solvent selection.
4. Remove piston cap [1]. Removing the piston
cap releases tension on all internal spray head
components. Remove spring retainer [2] and
piston spring [3], which are loose after removing
the piston cap.
5. Remove the air cap retainer [21] and air cap
[20]. Soak in a non-polar solvent if necessary. If
paint remains in the air cap holes, clean with a
toothpick or similar soft wood object. Air caps are
best cleaned in an ultrasonic cleaner.
> Never attempt to clean the air cap holes
with a wire or other metal object. Doing so
may damage the air cap, resulting in distor-
tion of the spray pattern.
