Prevent restart

To prevent the machine restarting (unintentionally) while there is someone inside the
danger zone, a padlock can be attached via the through hole on the actuator (see diagram).
As a result the actuator cannot engage with the safety switch, guard locking is not activated
and the machine is prevented from starting.
