Operation
Starting Operation
Inserting the battery
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 (7) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (9) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figure D)
The rotational direction switch (7) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (10) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (7) through to the left stop.
Left rotation: To loosen and unscrew screws, press the ro-
tational direction switch (7) through to the right stop.
Preselecting the Torque
The torque presetting ring (4) 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 symbol.
Mechanical gear selection
Only operate the gear selector (6) when the power
u
tool is not in use.
You can preselect two speed ranges with the gear selector
(6).
Gear I:
Low speed range; for screwdriving or working with a large
drilling diameter.
Gear II:
High speed range; for working with a small drilling diameter.
Setting the Operating Mode
Drilling
GSR
Set the torque presetting ring (4) to the
"drilling" symbol.
GSB
Set the operating mode presetting ring (5) to
the "drilling" symbol.
Screwdriving
GSR
Set the torque presetting ring (4) to the re-
quired torque.
GSB

Set the operating mode presetting ring (5) to
the "screwdriving" symbol.
Set the torque presetting ring (4) to the re-
quired torque.
Impact drilling (GSB)
Set the operating mode presetting ring (5) to
the "impact drilling" symbol.
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch (10) to varying ex-
tents.
Applying light pressure to the on/off switch (10) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Switching on/off
To start the power tool, press and hold the on/off switch
(10).
To switch off the power tool, release the on/off switch (10).
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder (1), are
locked when the on/off switch (10) is not pressed.
This enables screws to be screwed in even when the battery
(9) is empty and allows the power tool to be used as a
screwdriver.
Battery charge-control indicator
When the on/off switch (10) is pressed in halfway or com-
pletely, the battery charge-control indicator (11) indicates
the charge condition of the battery for several seconds. The
indicator consists of three green LEDs.
The three LEDs of the battery charge-control indicator (11)
and the lamp (12) flash urgently when the temperature of
the battery falls or rises outside the operating temperature
range of –20 to +50 °C.
LED
Continuous light 3 x green
Continuous light 2 x green
Continuous light 1 x green
Slowly flashing light 1 x green
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If there is an extreme overload, the power tool
switches off until the optimal operating temperature range is
reached again.
This status is indicated by the three battery charge indicator
(11) LEDs flashing in a chase sequence. The LEDs turn off if
the power tool has reached the optimum operating temper-
ature again.
Practical advice
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
