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 7 press the unlocking but-
tons 6 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.
Inserting
Pull the locking sleeve 3 toward the front and then
push the insert tool to the stop into the tool holder
2. The insert tool is automatically locked.

sert tool.

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
respirator.
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 8 to the centre
position in order to avoid unintentional starting. In-
sert the charged battery 7 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 8 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch 9 actuat-
ed.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 8 left to the
stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 8 through to the right stop.
Setting the torque
With the torque presetting ring 4 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
