Mechanical gear selection
Only operate the gear selector (4) when the power
u
tool is not in use.
You can preselect two speed ranges with the gear selector
(4).
First gear:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Second gear:
High speed range; for working with a small drilling diameter.
Always push the gear selector switch as far as it will
u
go. Otherwise, the power tool may become damaged.
Switching on/off
To start the power tool, press and hold the on/off switch
(12).
The worklight (23) lights up when the on/off switch (12) is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
Adjusting the speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (12) to varying extents.
A light pressure on the on/off switch (12) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Temperature-dependent overload protection
When used as intended, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted operating temperature range, the speed is re-
duced or the power tool is switched off. The power tool will
not run at full speed again until the permitted operating tem-
perature has been reached.
Activation of the temperature-controlled overload protector
is indicated by the LED on the power tool lighting up red.
– To return to within the permitted operating temperature
range, run the power tool at no load or wait until the LED
lights up green again.
When the LED lights up green, the tool has returned to
within the permitted operating temperature range.

User Interface (see figure I)
The user interface (10) is used to activate and deactivate the
precision clutch and for the "KickBack Control" rapid shut-
off, as well as for the status indicator of the power tool.
Precision Clutch
The precision clutch stops overlocking
when the set torque is reached, thereby re-
ducing clutch wear and the resulting noise.
The precision clutch can be deactivated on the
user interface (10) with the precision clutch button (24).
The current status is shown via the LED for precision
clutch (25) on the user interface (10).
Rapid Shut-off (KickBack Control)
The rapid shut-off function (KickBack Con-
trol) gives the user greater control over the
power tool and offers them better protec-
tion than power tools that do not have Kick-
Back Control. The power tool will switch off if it suddenly
and unforeseeably rotates around the drilling axis.
The rapid shut-off is indicated by the LED (20) flashing red,
flashing from the worklight (23) and the LED of the KickBack
Control (21) lighting up red on the power tool.
To switch the tool back on, release the on/off switch and
then press it again.
It will no longer be possible to switch the power tool
u
on if the KickBack Control function is faulty. Have the
power tool serviced by a qualified repair person using
only original replacement parts.
The rapid shut-off function can be deactivated on the user
interface (10) with the KickBack Control button (22). If the
power tool is not used for longer than 5 minutes or if the re-
chargeable battery is removed, the rapid shut-off function
automatically switches back on. The current status is shown
via the KickBack Control LED (21) on the user
interface (10).
Note: The warning light of the LEDs is not visible from
u
all directions! The warning light is difficult to see in
bright sunlight.

Run the power tool at no load and allow it to cool
