Battery Charging
Note: The battery is supplied partially charged. To
ensure full capacity of the battery, completely charge
the battery in the battery 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 procedure does not damage the battery.
The lithium-ion battery is protected against deep dis-
charging 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
WARNING
On/Off switch after the
machine has been automatically switched off.
The battery can be damaged.
The battery is equipped with a NTC temperature con-
trol which allows charging only within a temperature
range of between 0 °C and 45 °C. A long battery
service life is achieved in this manner.
Observe the notes for disposal.
Removing the Battery
The battery 5 is equipped with two locking levels that
should prevent the battery from falling out when
pushing the battery unlocking button 6 unintention-
ally. As long as the battery is inserted in the power
tool, it is held in position by means of a spring.
To remove the battery 5, press the unlocking button 6
and pull out the battery toward the front. Do not
exert any force.
Changing the Tool (see figure A)
❏ Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off switch
can lead to injuries.

holder, it can come loose again and not be con-
trolled.
Slide the application tool onto the square drive of the
tool holder 1.
Method of Operation
The tool holder 1 with the tool is driven by an electric
motor via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism in
action).
