Tool holder
The machine is available with three different tool holders:
SDS-max
Hexagonal with locking strap
Spline shaft
ON/OFF switch
A start-up protection is linked with the ON/OFF switch. This start-up protection
has the effect that the percussion rate or speed of the rotary hammer rises slowly
after pressing the ON/OFF switch. The start-up protection prevents or reduces
the chisel from slipping or the drill from jamming.
