Inserting the Tool

Key Chuck (see figure
Open the drill chuck until the tool can be inserted.
Insert the tool.
Clamp evenly in all three holes with the chuck
key 12.
Keyless Chuck (see figure
Inserting the Tool
Firmly hold the rear collar of the keyless chuck 1
and open it by turning the front collar, until tool
can be inserted.
Clamping the Tool
Hold the rear collar tight and firmly tighten the
front collar by hand, until the "clicking" of the lock-
ing action is no longer heard. This automatically
locks the chuck.
The locking system releases when the sleeve is
rotated in the opposite direction, in order to re-
move the tool.
Screwdriver Tools (GBM 10 RE/
GBM 10-2 RE/GBM 13-2 RE –
see figure )
D
The drill spindle 15 is equipped with a hexagonal
socket for use with screwdriver bits 14. The bit
can be inserted directly into the drill spindle 15
when the chuck is removed. There it is retained
by a securing ring.
Chuck Quick-Change Adapter
(GBM 10 SRE)
For fast converting from drilling to screwdriving,
the chuck can be removed quickly and simply
from the drilling spindle without additional tools:
To remove the quick-change adapter 19, hold the
chuck firmly and push the red lock button to the
front ( ).
Afterwards rotate the quick-change adapter 19 to
the right ( ); this releases the adapter and it can
be removed.

Initial Operation

Observe correct mains voltage: The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching On and Off
To start the machine, press the On/Off switch 5
and keep it depressed.
GBM 10 RE/GBM 10 SRE/
GBM 10-2 RE/GBM 13-2 RE: The
machine runs with variable speed
between 0 and maximum, depend-
ing on the pressure applied to the
On/Off switch 5. Light pressure re-
sults in a low rotational speed thus
allowing smooth, controlled starts.
Do not strain the machine so heav-
ily that it comes to a standstill.
Lock the pushed On/Off switch 5 by pressing the
lock-on button 3.
To switch off the machine, release the On/Off
switch 5 or push and release it then.
Reversing the Rotational Direction
(GBM 10 RE/GBM 10 SRE/
GBM 10-2 RE/GBM 13-2 RE)
Operate the rotational direction switch 6 only
at a standstill.
Set the rotational direction switch 6 to R (right-
hand rotation) or L (left-hand rotation). (When the
On/Off switch 5 is actuated, the rotational direc-
tion switch 6 is locked.)
The left-hand rotation enables screws or nuts to
be unscrewed.
Gear Selection, Mechanical
(GBM 10-2 RE/GBM 13-2/GBM 13-2 RE)
Two speed ranges can be preselected with the
gear selector 7:
Speed I: Lower rpm range
Speed II: Higher rpm range
The speed can be switched during drill operation.
However, this should not be done while operating
at full load.
