Starting Operation
Observe correct mains voltage! The voltage

Reversing the Rotational Direction
(GBH 2-26 RE/DRE/DFR)
The rotational direction switch 7 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 9 actuated.
Right rotation: Turn the selector switch for
drilling/hammer drilling 7 on both sides to
the stop in the position
Left rotation: Turn the selector switch for
drilling/hammer drilling 7 on both sides to
the stop in the position
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 9.
To lock the On/Off switch, keep it pressed and
additionally push the lock-on button 8.
To switch off the machine, release the On/Off
switch 9. When the On/Off switch 9 is locked,
press it first and then release it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on pow-
er tool can be variably adjusted, depending on
how far the On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Safety Clutch
If the tool insert becomes caught or
jammed, the drive to the drill spindle is in-
terrupted. Because of the forces that occur,
always hold the power tool firmly with both
hands and provide for a secure stance.
If the power tool jams, switch the machine
off and loosen the tool insert. When switch-
ing the machine on with the drilling tool
jammed, high reaction torques can occur.
