Switches marked as 'reserved' might carry production-related functions and can cause the
blade to malfunction if their setting is changed.
Therefore, do not change settings of switches marked as 'reserved'. The setting of switches
which are not marked as 'reserved' has to be checked and changed before blade installation.
Blade Damage
Setting/resetting the switches during operation can cause blade damage.
