Switching On/Off
To switch on the machine, press the on/off switch 9.
To lock on, press the on/off switch 9 and lock by
pressing the locking button 8.
To switch off, release the on/off switch 9. When
locked, first press the on/off switch 9 and then release.
Speed Regulation
By increasing or decreasing the pressure on the on/off
switch 9, the speed of the switched-on machine can
be continuously regulated.
Reduced speed of the machine facilitates the starting
of holes (e.g., on smooth surfaces such as tiles), pre-
vents the slipping of the drill and the splintering of the
drilled hole.
Recommended Speed Ranges:
– High speed for hammer drilling in concrete or stone
as well as for chiselling
– Medium speed for drilling in steel and wood
– Low speed for driving screws and cutting threads.

Working Instructions

Chiselling
The SDS-plus tool can be turned in the tool holder to
various positions to achieve an optimum and low-fa-
tigue working position.
Turn the operating mode selection switch 11 to posi-
