•Screw the support cup (E) onto the output shaft threads (CAUTION! Left-hand thread). Tighten to a torque of 35- 50 Nm (3.5-5.0 kpm). Use the socket spanner in the tool kit. Note that the locking pin (C) must remain inside the gear housing to lock the drive disk. Hold the shaft of the socket spanner as close to the blade guard/combination guard as possible.

The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut.
