Assembly
Battery Charging (see figure A)
Note: The battery supplied is partially charged. To
ensure full capacity of the battery, completely
charge the battery in the battery charger before us-
ing your power tool for the first time.
The lithium-ion battery can be charged at any time
without reducing its service life. Interrupting the
charging procedure does not damage the battery.
The lithium-ion battery is protected against deep
discharging by the "Electronic Cell Protection
(ECP)". When the battery is empty, the machine is
switched off by means of a protective circuit: The
inserted tool no longer rotates.
 Do not continue to press the On/Off switch af-
ter the machine has been automatically
switched off. The battery can be damaged.
To remove the battery 5 press the unlocking but-
tons 4 and pull out the battery downwards. Do not
exert any force.
Observe the notes for disposal.
Changing the Tool (see figure B)
 Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool. There is danger of injury
when unintentionally actuating the On/Off
switch.
The drill spindle is locked when the On/Off switch
7 is not pressed. This makes quick, convenient and
easy changing of the tool in the drill chuck possi-
ble.
Open the keyless chuck 1 by turning in rotation di-
rection , until the tool can be inserted. Insert the
tool.

Firmly tighten the collar of the keyless chuck 1 by
hand in rotation direction .

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 reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dust, such as oak or beech dust, is con-
sidered carcinogenic, especially in connection
with wood-treatment additives (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 res-
pirator.
Observe the relevant regulations in your country for
the materials to be worked.
 Prevent dust accumulation at the workplace.
Dust can easily ignite.
Operation

Starting Operation

Inserting the battery
Note: Use of batteries not suitable for the machine
can lead to malfunctions of or cause damage to the
power tool.
Set the rotational direction switch 6 to the centre
position in order to avoid unintentional starting. In-
sert the charged battery 5 into the handle so that it
can be felt to engage and faces flush against the
handle.
Reversing the rotational direction (see figure C)
The rotational direction switch 6 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch 7 actuat-
ed.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 6 left to the
stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 6 through to the right stop.
Setting the torque
With the torque presetting ring 2 the required
torque setting can be preselected in 20 steps. With
the correct setting, the insert tool is stopped as
soon as the screw is screwed flush into the material
or when the adjusted torque is reached. The safety
