Operation
Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Setting the Operating Mode
With the selector switch for drilling/hammer
drilling 7, the operating mode of the machine is
selected.
Note: Change the operating mode only when
the machine is switched off! Otherwise, the
machine can be damaged.
To change the operating mode, press the re-
lease button 6 and turn the drilling/hammer
drilling selector switch 7 to the desired position
until it can be heard to latch.

Reversing the Rotational Direction (GBH 2 SR)
The rotational direction switch 11 is used to
reverse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 4 actuated.
Right rotation: Push the rotation-
al direction switch 11 rightward
to the stop.
Left rotation: Push the rotational
direction switch 11 leftward to
the stop.
Set the direction of rotation for hammer drilling,
drilling and chiselling always to right rotation.
Switching On and Off
To start the machine, press the On/Off switch 4.
To lock the On/Off switch, keep it pressed and
additionally push the lock-on button 5.
GBH 2 SR: In left rotation, the On/Off switch
cannot be locked.
To switch off the machine, release the On/Off
switch 4. When the On/Off switch 4 is locked,
press it first and then release it.
Setting the Speed/Impact Rate
(GBH 2 SE/GBH 2 SR)
The speed/impact rate of the switched on
power tool can be variably adjusted, depending
on how far the On/Off switch 4 is pressed.
Light pressure on the On/Off switch 4 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
