Assembly
Removing the Battery (see figure A)
 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 re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The llithiucm-ion battery is protected against deep discharg-
ing by the "Electronic Cell Protection (ECP)". When the bat-
tery is empty, the machine is switched off by means of a pro-
tective 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.
To remove the battery 8 press the unlocking buttons 7 and
pull out the battery downwards. Do not exert any force.
Observe the notes for disposal.
Changing the Tool
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.

 Regularly clean the power tool's air vents. The motor's
fan will draw the dust inside the housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.

 When working with an application tool, pay attention
that the application tool is connected securely on the
tool holder. When the application tool is not securely con-
nected with the tool holder, it can come off during applica-
tion.
Slide the application tool 16 onto the square drive of the tool
holder 1.
However based on the system, if the application tool 16 ap-
pears wobbly after connecting securely on the tool holder 1;
this has no influence on the function/safety.
Operation
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).
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.
