Tool Specifications
Intended Use
The machine is intended for hammer drilling in con-
crete, brick and stone as well as for chiselling. It is
also suitable for drilling without impact in wood,
metal, ceramic and plastic.
The user is responsible for damage caused by usage
other then intended.
Before Putting into Operation
The batteries are partially charged and delivered in
idle state. The battery must be activated before using
for the first time. For this, place the battery onto the
charger for a short time. The LED on the battery indi-
cates the charge condition.
When the battery is not used for longer periods, it
switches to the idle state. In order to use the battery
again, it must be reactivated.
When the battery is completely discharged, it
switches off automatically (deep discharging not
possible). When the power tool is switched on none-
theless, the battery delivers only brief current pulses.
The power tool “flickers” as an indication that the
battery must be charged.
As a general rule: Should the power tool not be
operative after inserting the battery, place the bat-
tery onto the charger. The indicators on the battery
and the charger then provide information about the
battery condition.
At low temperatures, further operation is possible
with reduced power output. The battery switches off
automatically below -10 °C.
Battery Charging
A battery that is new or has not been used for a
longer period does not develop its full capacity until
after approximately 2 – 3 charging/discharging
cycles.
To remove the battery
10
, push back the release but-
ton
9
and pull the battery out downwards.
Do not
exert any force.
Please refer to the enclosed “Battery Charger”
instructions for the operation of the battery charger
as well as for a description of the charging process.
The battery is equipped with an NTC temperature
control which allows charging only within a temper-
ature range of between -10 °C and +66 °C. A long
battery service life is achieved in this manner.
A significantly reduced working period after charg-
ing indicates that the batteries are used and must be
replaced.
