  (2) Unscrew bearing retainer clockwise with No.1R043 "wrench for bearing retainer".
       See Fig.2.
       The bearing retainer can not be separated from gear housing completely in this process, because
              spindle blocks bearing retainer.

Caution
  The caution is carved on the side grip for Model PV7000C as illustrated in Fig. 11.
  For efficiently prevention of static electricity accumulation, the above side grip is conductive in comparing with
  other side grips. Therefore, you would not be protected from electric shock, when you would hit the live wire
  with the other machine equipped with this side grip, for example, drill, hammer drill or angle grinder, etc.
