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.
Removing the battery (see figure A)
To remove the battery (8), press the release button (7) and
pull the battery downwards out of the power tool. Do not
use force to do this.
You can also leave the battery (8) inserted in the power tool
for charging. While it is charging, the power tool cannot be
switched on. Press the on/off switch (10) to retrieve the bat-
tery charge status. For more information, see the "Battery
charge indicator" section.
Follow the instructions on correct disposal.
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.
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 keyless chuck (2) by turning it by hand in
the direction of rotation ➋. 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 (6) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (8) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figure C)
Only operate the rotational direction switch (6) when
u
the power tool is not in use.
The rotational direction switch (6) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (10) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (6) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (6) through to the right
stop.
Setting the operating mode
Drilling
Set the operating mode presetting ring (4) to
the "drilling" symbol.
Screwdriving
Set the operating mode presetting ring (4) to
the "screwdriving" symbol.
Set the torque presetting ring (3) to the re-
quired torque.
Impact drilling
Set the operating mode presetting ring (4) to
the "impact drilling" symbol.
Pre-selecting the torque
The torque presetting ring (3) can be used to pre-select the
required torque in 20 stages. Once the set torque has been
reached, the application tool will be stopped.
Mechanical gear selection
Only operate the gear selector (5) when the power
u
tool is not in use.
You can preselect two speed ranges with the gear selector
(5).
First gear:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Second gear:
High speed range; for working with a small drilling diameter.
