Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject to overload.
When the load is too high or the allowable battery temperature of 70 °C is
exceeded, the electronic control switches off the power tool until the tem-
perature is in the optimum temperature range again.
In case of overload, the battery charge-control indicator 5 additionally
flashes three times red and the "Power Light" 9 flashes three times white.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging by the "Elec-
tronic 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.
Working Advice
Apply the power tool to the screw only when it is switched off. Ro-
tating tool inserts can slip off.
After longer periods of working at low speed, allow the machine to cool
down by running it for approx. 3 minutes at maximum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill bits
(HSS=high-speed steel). The appropriate quality is guaranteed by the
Bosch accessories program.
Before screwing larger, longer screws into hard materials, it is advisable
to predrill a pilot hole with the core diameter of the thread to approx.
of the screw length.

Maintenance and Cleaning

Before any work on the machine (e. g., maintenance, tool change,
etc.) as well as during transport and storage, set the rotational di-
rection switch to the centre position. Unintentional actuation of the
On/Off switch can lead to injuries.
For safe and proper working, always keep the machine and venti-
lation slots clean.
When the battery is no longer operative, please refer to an authorised af-
ter-sales service agent for Bosch power tools.
