Adjusting the Drilling Depth on the Dust Extrac-
tion Attachment (see figure K)
The required drilling depth X can also be adjusted
when the dust extraction attachment is mounted.
Insert the SDS-plus drilling tool to the stop into the
SDS-plus tool holder 3. Otherwise, the movability of the
SDS-plus drilling tool can lead to incorrect adjustment
of the drilling depth.
Loosen the wing bolt 25 on the dust extraction attach-
ment.
Without switching the power tool on, apply it firmly to
the drilling location. The SDS-plus drilling tool must
face against the surface.
Position the the guide pipe 26 of the dust extraction at-
tachment in its holding fixture in such a manner that the
head of the dust extraction attachment faces against the
surface to be drilled. Do not slide the guide pipe 26 fur-
ther over the telescopic pipe 24 of the dust extraction at-
tachment than required, so that as much as possible of
the scale 24 on the telescopic pipe remains visible.
Retighten the wing bolt 25 again. Loosen the clamping
screw 22 on the depth stop of the dust extraction
attachment.
Move the depth stop 23 on the telescopic pipe 24 in
such a manner that the clearance X shown in the figure
corresponds with the required drilling depth.
Tighten the clamping screw 22 in this position.
Operation

Starting Operation

Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specified on the type plate of the power tool.
Setting the Operating Mode
The operating mode of the power tool is selected with
the mode selector switch 11.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine can
be damaged.
To change the operating mode, push the release but-
ton 10 and turn the mode selector switch 11 to the
requested position until it can be heard to latch.

Reversing the Rotational Direction
(GBH 2-26 RE/DRE/DFR)
The rotational direction switch 7 is used to reverse 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 drill-
ing/hammer drilling 7 on both sides to the stop in
the position .
Left rotation: Turn the selector switch for drill-
ing/hammer drilling 7 on both sides to the stop in
the position .
Set the direction of rotation for hammer drilling, drilling
and chiseling 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 addi-
tionally 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 power 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.
