Restart interlock

To prevent the machine restarting while there is someone inside the danger zone, a pad-
lock can be attached to one of the locking levers (see illustration). As a result, the guard
locking element cannot engage in the bolt tongue, the guard locking device is not activated
and the machine is prevented from restarting.
The padlock's shackle diameter may be max. 8 mm.
