Operation
English
Starting Operation
English
Inserting the battery
English
Note: The use of batteries unsuitable for your
power tool can lead to malfunctions or damage to
the power tool.
Set the rotational direction switch (6) to the
middle position to avoid unintentionally switching
it on. Insert the charged battery (5) into the
handle until you feel it engage and it is flush with
the handle.
Setting the rotational direction (see figure C)
The rotational direction switch (6) is used to
change the rotational direction of the power tool.
However, this is not possible while the on/off
switch (7) is being pressed.
Right rotation: To drill and to drive in screws,
press the rotational direction switch (6) through to
the left stop.
Left Rotation: To loosen and unscrew screws and
nuts, press the rotational direction switch (6)
through to the right stop.
Preselecting the Torque
English
The torque presetting ring (2) can be used to
preselect the required torque in 20 stages. When
the correct setting is used, the application tool will
be stopped when the screw is driven flush into the
material or once the set torque has been reached.
In position
the overload clutch is deactivated,
e.g. for drilling.
When unscrewing screws, you can select a higher
setting or set the tool to the
Mechanical gear selection
Only operate the gear selector (3) when the
u
power tool is not in use.
You can preselect two speed ranges with the gear
selector (3).
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.
If the gear selector switch (3) cannot be pushed
all the way, turn the drill chuck slightly with the
drill.
Switching on/off
English
To start the power tool, press and hold the on/off
switch (7).
The lamp (9) lights up when the on/off switch (7)
is lightly or fully pressed, meaning that the work
area is illuminated in poor lighting conditions.

symbol.
English
To switch off the power tool, release the on/off
switch (7).
Adjusting the Speed
English
You can adjust the speed of the power tool when
it is on by pressing in the on/off switch (7) to vary-
ing extents.
A light pressure on the on/off switch (7) results in
a low rotational speed. Increased pressure on the
switch causes an increase in speed.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder, are
locked when the on/off switch (7) is not pressed.
This enables screws to be screwed in even when
the battery (5) is empty and allows the power tool
to be used as a screwdriver.
Run-out brake
English
Upon releasing the on/off switch (7), the drill
chuck is slowed down, which prevents the applic-
ation tool from continuing to rotate.
When driving in screws, you should therefore only
release the on/off switch (7) once the screw has
been inserted flush into the workpiece. This way,
the head of screw will not penetrate the work-
piece.
Battery charge-control indicator
When the on/off switch (7) is pressed in halfway
or completely, the battery charge-control indicator
(8) indicates the charge condition of the battery
for several seconds. The indicator consists of
three green LEDs.
LEDs
3× continuous green light
2× continuous green light
1× continuous green light
1× flashing green light
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot
be overloaded. In the event of heaving loading or
the temperature rising/falling outside the permit-
ted battery temperature range, the speed will be
reduced. The power tool will not run at full speed
again until the permitted battery temperature has
been reached.
Practical advice
English
Only apply the power tool to the screw/nut
u
when the tool is switched off. Rotating tool in-
serts can slip off.
After working at a low speed for an extended
period, you should operate the power tool at the
maximum speed for approximately three minutes
without load to cool it down.
