Observe the notes for disposal.
Changing the Tool (see figure B)
 Before any work on the power tool, remove the battery.

sert tool to the stop into the tool holder 2. The insert tool is au-
tomatically locked.
Removing

Dust/Chip Extraction
 Dusts 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 dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dusts 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.
Reversing the rotational direction (see figure C)
The rotational direction switch 4 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 5 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 4 left to the stop.
Left Rotation: For loosening or unscrewing screws, push the
rotational direction switch 4 right to the stop.
Setting the torque
With the torque selector switch 6, you can preselect the re-
quired torque in 8 steps. When the torque setting is adjusted
correctly, the insert tool is stopped as soon as the screw is
driven flush into the material or when the set torque is
reached. In the " " position, the safety clutch is deactivat-
ed; e.g., for drilling.
In left rotation the safety clutch is deactivated.

Switching On and Off
To start the machine, press the On/Off switch 5 and keep it
pressed.
To switch off the machine, release the On/Off switch 5.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 5 is pressed.
Light pressure on the On/Off switch 5 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 5 is not pressed, the drill spindle and
thus the tool holder are locked.
This enables screws to be screwed in, even when the battery
is empty and allows for the machine to be used as a screw-
driver.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is placed under too much pressure or
the permitted battery temperature range is left, the tool
switches off. Following an automatic shut-off, switch off the
power tool, allow the battery to cool and then switch the pow-
er tool back on.
Protection Against Deep Discharging
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.
Angle Selection of Drill Head (see figure D)
The drill head can be locked in 5 different angle positions.
Push the release button 7 and swivel the tool head to the re-
quired position. Then, let go of the release button 7 again.
 Before starting operation, check if the drill head is
locked in the respective angle position. Danger of injury.
Working Advice
 Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
Utility Clip
The swivelling utility clip 8 can be used to hang the power tool
onto a hook. In this manner, both hands are free and the pow-
er tool is ready to hand.
