Reversing the Rotational Direction
(GBH 2-24 DSR)
The rotational direction switch 11 is used to re-
verse 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 2-24 DSR: 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 2-24 DSE/GBH 2-24 DSR)
The speed/impact rate of the switched on pow-
er 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.
