> During this operation, be
CAREFUL that
the interior surface of packing chamber is NOT
damaged (marred or scratched)! This chamber
is a seal area and the barrel assembly will have
to be replaced if it is damaged.
3. Unscrew needle/electrode from shaft and slide
parts off of the shaft (see Figure 7).
4. Inspect and replace parts as necessary. Since
the needle shaft in the REA 9000W does not
move, the packing wear should be minimal.
