The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised 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 repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal 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
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.
Battery Charging (see figure A)
Do not use other battery chargers. The sup-
plied battery charger is designed for the Lith-
ium-Ion battery in your machine.
Observe the mains voltage! The voltage of
the power supply must correspond with the
data given on the nameplate of the battery
charger. Battery chargers marked with 230 V
can also be operated with 220 V.
Note: The battery is supplied partially charged.
To ensure full capacity of the battery, complete-
ly charge the battery in the battery charger be-
fore using your power tool for the first time.
The lithium ion battery can be charged at any
time without reducing its service life. Interrupt-
ing the charging procedure does not damage the
battery.
The lithium ion battery is protected against
deep discharging by the "Electronic Cell Protec-
tion (ECP)". When the battery is empty, the ma-
chine 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 ma-
chine has been automatically switched off. The
battery can be damaged.
