Protection Against Deep Discharging
The Li-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the bat-

protective circuit: The inserted tool no longer rotates.

Apply the power tool to the screw only when it is
switched off. Rotating 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

is guaranteed by the Bosch accessories program.

chine and ventilation slots clean.
