Resistor Replacement
See Figure 6-3.
1. Perform steps 1 through 4 of the Powder Path Repair procedure.
2. Unscrew the old resistor probe (2) from the multiplier (4). Clean the
exposed threads in the end of the multiplier and wipe the multiplier
well (5) with a clean cloth.
WARNING: All air must be replaced by dielectric grease in the multiplier
well, resistor holder, and contact tip. High voltage can arc through air
pockets, burn through the multiplier or resistor probe, and create a fire or
explosion hazard.
3. Inject dielectric grease into the multiplier well (5) until it is completely full.
Use the applicator shipped with the resistor kit.
4. Fill the new resistor spring (3) and resistor probe cavity (6) completely
with dielectric grease.
5. Unscrew the new contact tip (1) from the resistor probe.
6. Screw the new resistor probe onto the multiplier and tighten it securely.
7. Apply dielectric grease to the threads of the new contact tip and into the
end of the probe.
8. Screw the contact tip into the resistor probe end and tighten it securely.
Do not overtighten. Wipe the excess dielectric grease off the contact tip,
resistor probe, and multiplier.
9. Install the wear sleeve over the resistor probe. Install the powder inlet
body, nozzle, and hose adapter.
