The machine is intended for driving in and loosening
screws, for drilling in wood, metal, ceramic and plastic,
and for impact drilling in brick and lime-sand brick.
For damage caused by usage other then intended, the
user is responsible.
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 indicates 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 nonetheless, 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 opera-
tive after inserting the battery, place the battery onto the
charger. The indicators on the battery and the charger
BS 28-A Combi
then provide information about the battery condition.
