Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Removing the battery (see figure A)
To remove the battery (10), press the release button (9)
and pull the battery back and out of the power tool. Do not
use force to do this.
Charging the Battery
Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using 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 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.

Battery charge indicator

When the on/off switch (13) is pressed in halfway or com-
pletely, the battery charge-control indicator (12) indicates
the charge condition of the battery for several seconds. The
indicator consists of three green LEDs.
LED
Continuous light 3 x green
Continuous light 2 x green
Continuous light 1 x green
Slowly flashing light 1 x green
The three LEDs in the battery charge indicator flash
quickly when the temperature of the battery is outside
the operating temperature range of –30 to +65 °C and/or
the overload protection has been triggered.
Changing the Tool (see figure B)
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-

moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
The drill spindle is locked when the on/off switch (13) is not
pressed. This makes it possible to change the application
tool in the drill chuck quickly, conveniently and easily.
Open the keyless chuck (2) by turning it in the direction of
rotation ➊ until the tool can be inserted. Insert the tool.
Firmly tighten the sleeve of the keyless chuck (2) by turning
it by hand in the rotational direction ➋ until it stops clicking.
This will automatically lock the drill chuck.

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 (8) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (10) into the handle until you feel it engage and it is
flush with the handle.
Set the rotational direction (see figure C)
The rotational direction switch (8) is used to change the ro-
Capacity
tational direction of the power tool. However, this is not pos-
≥ 75%
sible while the on/off switch (13) is being pressed.
50 – 75 %
Right rotation: To drill and to drive in screws, press the ro-
26 – 50 % tational direction switch (8) through to the left stop.
≤ 25%
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (8) through to the right
stop.
The rotational direction indicator for right rotation
(6) lights up when the on/off switch (13) is
pressed and the motor is running.
The rotational direction indicator for left rotation
(7) lights up when the on/off switch (13) is
pressed and the motor is running.
