Assembly
Battery Charging
 Use only the battery chargers listed on the accessories
page. Only these battery chargers are matched to the lith-
ium ion battery of your power tool.
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 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 after the
machine has been automatically switched off. The bat-
tery can be damaged.
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 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 7 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 8 unintentionally. 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 7, press the unlocking button 8 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 stor-
age, set the rotational direction switch to the centre
position. Unintentional actuation of the On/Off switch can
lead to injuries.
Inserting
Pull the locking sleeve 2 forward, push the insert tool to the
stop into the tool holder 1 and release the locking sleeve 2 to
lock the insert tool.
Use only screwdriver bits with ball catch 12 (DIN 3126-
E6.3). Other screwdriver bits 14 can be used with a universal
bit holder with ball catch 13.
Removing
Pull the locking sleeve 2 forward and remove the insert tool.
Operation
Operation Method Impact Driving
–
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).
The impact mechanism is activated as soon as the screwed
connection runs tight and thus load is put on the motor. In this
instance, the impact mechanism converts the power of the
motor to steady rotary impacts. When loosening screws or
nuts, the process is reversed.
