The vibration level given in this information sheet
has been measured in accordance with a standard-
ised test given in EN 60745 and may be used to
compare one tool with another. It may be used for
a preliminary assessment of exposure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with different
accessories or insertion tools or is poorly main-
tained, the vibration emission may differ. This may
significantly increase the exposure level over the
total working period.
An estimation of the level of exposure to vibration
should also take into account the times when the
tool is switched off or when it is running but not ac-
tually doing the job. This may significantly reduce
the exposure level over the total working period.
Identify additional safety measures to protect the
operator from the effects of vibration such as:
maintain the tool and the accessories, keep the
hands warm, organisation of work patterns.
Assembly
Battery Charging
Note: The battery supplied is partially charged. To
ensure full capacity of the battery, completely
charge the battery in the battery charger before us-
ing 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 af-
ter the machine has been automatically
switched off. The battery can be damaged.
Removing the battery
The battery 12 is equipped with two locking levels
that should prevent the battery from falling out
when pushing the battery unlocking button 13 un-
intentionally. 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 12:
– Push the battery against the base of the power
tool (1.) and at the same time press the battery
unlocking button 13 (2.).
– Pull the battery out of the power tool until a red
stripe becomes visible (3.).
– Press the battery unlocking button 13 again and
pull out the battery completely.
Battery Charge-control Indication
The three green LEDs of the battery charge-control
indicator 15 indicate the charge condition of the
battery 12. For safety reasons, it is only possible to
check the status of the charge condition when the
machine is at a standstill.
Push button 16 to indicate the charge condition (al-
so possible when the battery is removed). The bat-
tery charge-control indicator automatically goes
out after approx. 5 seconds.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
When no LED lights up after pushing button 16,
then the battery is defective and must be replaced.
During the charging procedure, the three green
LEDs light up one after the other and briefly go out.
The battery is fully charged when the three green
LEDs light up continuously. The three LEDs go out
again approx. 5 minutes after the battery has been
fully charged.
The battery is equipped with a NTC temperature
control which allows charging only within a temper-
ature range of between 0 °C and 45 °C. A long
battery service life is achieved in this manner.
Auxiliary Handle
Operate your machine only with the auxiliary
handle 17.
Changing the position of the auxiliary handle
(see figure A)
The auxiliary handle 17 can be set to any position
for a secure and low-fatigue working posture.
Turn the wing bolt for adjustment of the auxiliary
handle 11 in anticlockwise direction and set the
