4. Place the nozzle and nozzle nut in an ultrasonic
cleaner to remove any impact fusion, then blow
them off with compressed air. If desired,
remove the nozzle nut from the nozzle by
sliding the nut forward then turning it clockwise
to unscrew it.
5. Blow off the insert and filter. If the filter is
clogged with powder, remove it and replace it
with a new one. When removing the new style
filter from the insert, be careful not to scratch
the inside surface of the insert.
To re-assemble the nozzle:
1. Make sure the electrode ring is threaded all the
way onto the insert.
2. Thread the tool onto the threaded end of the
insert.
3. Turn the tool counterclockwise to remove it
from the insert. Check the nozzle. The
electrode ring should be approximately
1
/
4
inch
inside the nozzle lip.

All internal components, except the electrodes, are the same for all nozzles. For flat-spray, cross, and pinpoint
nozzles, the electrode is glued into the nozzle shell with epoxy and cannot be replaced separately.
