General Care, Troubleshooting and Service
6-9
Cleaning or Replacing the Positive Charger Needle
W A R N I N G
High voltage is accessible in several locations within this instrument.
Make sure you unplug the power source to the instrument before
performing maintenance procedures.
The procedure for cleaning or replacing the positive charger needle is nearly
identical to that for the negative charger needle, with the following
exceptions:
Before cleaning or replacing the positive charger needle, you must
disconnect the charger sheath flow tubing (Figure 6-8).
You must push
the retaining ring evenly into the connector before pulling the hose
free. If you try to simply pull on the hose, it will become harder to
remove.
The positive charger is the bottom set of screws (see Figure 6-9) on the
charger head assembly.
The positive charger does not have a honeycomb. Beneath the positive
charger is a grid (screen) which you do not need to remove.
When reassembling the positive charger, take care to protect the wire
tip from bending over by coming in contact with the coarse wire mesh
when inserting it through the hole in the center of the mesh.
