Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Hammer drilling into concrete: Vibration emis-
sion value a
=17.5 m/s
h
Drilling into metal: Vibration emission value

a
=2.9 m/s
, Uncertainty K=1.5 m/s

Screwdriving: Vibration emission value

=2.5 m/s
, Uncertainty K=1.5 m/s
h
The vibration emission level given in this informa-
tion 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 ex-
posure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing 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 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
Before any work on the machine (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional 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.
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. Interrupt-
ing the charging procedure does not damage the
battery.
The Li-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.
WARNING
chine has been automatically switched off. The
battery can be damaged.
The battery is equipped with a NTC temperature
control which allows charging only within a tem-
perature range of between 0 °C and 45 °C. A long
battery service life is achieved in this manner.
