4. Remove the trigger adjustment nut if it was
required when pulling the needle shaft from the
barrel packing chamber. Then remove the packing
nut, spacer, rear seal retainer sub-assembly, and
packing tube from the rear of the needle shaft.
The spring loaded u-cup and o-ring can now be
re-moved from the rear seal retainer.
† If the spacer and seal retainer do not
separate easily, wedge a knife blade be-
tween them and pry them apart.
NOTE

5. Unscrew needle/electrode from shaft and slide
the male chevron adapter, the chevron seals and

6. Remove retaining ring and air cap from barrel.
7. Loosen the fluid nozzle using the special
multi-purpose wrench and unscrew it by hand to
remove.
Cleaning and Inspection
1. Clean the packing chamber of the barrel with a
suitable solvent and a soft bristle bottle brush. DO
NOT submerge or soak the barrel in solvent.
If the chamber has dry paint in it and cannot be
cleaned out, the barrel MUST BE REPLACED.
2. Examine the plastic section of the needle shaft
and the packing tube for signs of carbon tracking.
Also, inspect the air passages and packing cham-
ber of the barrel for signs of scratches, additional
carbon tracking, or dried paint. Shine a small
flashlight into the front of the barrel to highlight
any damage in these areas.
3. From time to time it is desirable to test the elec-
trical integrity of the 70430-01 resistive electrode
(see "Needle/Electrode Resistance Testing" in the
"Maintenance" section).
Reassembly
(Refer to Figures 15, 16, 17, 18, and 19)

† Soaking or submerging the barrel could
allow solvents into the high voltage section of
the barrel, leading to applicator failure and/or
possible dangerous conditions that could re-
sult in property damage and personnel injury.
