The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
Follow the instructions on correct disposal.
Removing the battery (see figure A)
To remove the battery (9), press the release buttons (8) and
pull the battery downwards out of the power tool. Do not
use force to do this.
Follow the instructions on correct disposal.
Battery charge-control indicator
When the on/off switch is pressed in halfway or completely,
the battery charge indicator indicates the charge condition
of the battery for several seconds. It consists of an LED
which lights up in three colours.
LED
Green continuous light
Orange continuous light
Red continuous light
Flashing light, red
Changing the tool (see figure B)
Open the keyless chuck (2) by turning it in the direction of
rotation ➋ until the tool can be inserted. Insert the tool.
Firmly tighten the keyless chuck (2) by turning it by hand in
the direction of rotation ➊.

Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.

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 (10) to the middle posi-
tion 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 C)
The rotational direction switch (10) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (11) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (10) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (10) through to the
right stop.
Preselecting the Torque
The torque presetting ring (3) can be used to preselect the
Capacity
required torque in 20 stages. When the correct setting is
≥66 %
used, the application tool will be stopped when the screw is
33–66 %
driven flush into the material or once the set torque has been
reached. In position
≤11–33 %
e.g. for drilling.
≤11 %
When unscrewing screws, you can select a higher setting or
set the tool to the
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).
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.
If the gear selector switch (4) cannot be pushed all the way,
turn the tool holder (1) with the application tool slightly.
Switching on/off
To start the power tool, press and hold the on/off switch
(11).
To switch off the power tool, release the on/off switch (11).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (11) to varying extents.
A light pressure on the on/off switch (11) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
