Reinstall
1. Check the electrode tightness on the needle
shaft. If it is loose, tighten it (refer to "Needle/
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 79854-00 with 3/8" square. Torque to 40
to 45 lbs. - in. (4.5-5.1 Nm). An alternate method
(if no torque wrench is available) is to hand tighten,
then tighten an additional 1/16 turn in the clockwise
direction.
4. Install the air cap and retaining ring onto the
applicator.
Figure 26: Reinstalling Fluid Nozzle
† TIGHTEN PROPERLY
Do not under-tighten the fluid nozzle as
fluid can leak into the air passages. See
torque range specified.
Do not over-tighten the fluid nozzle into
the barrel. Doing so could damage or break
the fluid nozzle or damage the thread of
the barrel.
NEEDLE / ELECTRODE
Removal
1. Remove the air cap and fluid nozzle from the
applicator assembly.
2. Secure the needle shaft at the rear of the barrel
with the Special Wrench 79854-00 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.
