NOTE
Figure 19: Air Cap, Fluid Nozzle, and Nut
If the fluid nozzle is replaced, there is a good
chance that the needle/electrode assembly will need
to be replaced also. A worn needle/electrode assem-
bly may not always seat well in a new fluid nozzle.

Reinstall
1. Check the needle/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 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 tighten 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).
