Reinstall
1. Check the needle/electrode tightness on the
needle shaft. If it is loose, tighten it (refer to "Nee-
dle/Electrode" in the "Maintenance" section).
2. With the applicator trigger actuated, place the
fluid nozzle over the needle/electrode and screw
it into the barrel by hand.
3. Tighten it using the special multi-purpose
wrench with 3/8" square. Torque to 40-45 lbs - in
(4.5-5.1 Nm). An alternate method (if no torque
wrench is available) is to hand tighten, then tight-
en an additional 1/16 to 1/8 turn in the clockwise
direction.
4. Install the air cap and retaining ring onto the
applicator (refer to "Air Cap - Reinstall" in the
"Maintenance" section).

Removal
1. Remove the air cap and fluid nozzle from the
applicator assembly.
2. Secure the needle shaft at the rear of the barrel
and unscrew the needle/electrode from the needle
shaft.
Cleaning and Inspection
1. Use a suitable solvent to clean the needle/
electrode.
2. Examine the needle/electrode for damage or
wear. Pay special attention to the area where
the wire electrode extends from the main body.
This is a sealing surface that seats inside the fluid
nozzle. If there are signs of wear in this area,
both the needle/electrode and fluid nozzle must
be replaced.
3. An electrical check of the needle/electrode must
be done prior to reinstalling it into the applicator
assembly (refer to "Needle/Electrode Resistance
Testing" in the "Maintenance" section).
Reinstall
1. Secure the needle shaft at the rear of the barrel
and screw the needle/electrode into place by hand.
2. Reinstall the fluid nozzle and air cap onto the
barrel.
