Run-on Brake
When the On/Off switch 10 is released, the
chuck brakes to a stop, thus preventing the run-
on of the tool.
When driving in screws, wait until the screw is
screwed in flush with the material and then re-
lease the On/Off switch 10. By doing so, the head
of the screw does not penetrate into the materi-
al.
Battery Charge-control Indication
The battery charge-control indicator 8 consists of
three green LEDs, and indicates the charge con-
dition of the battery for a few seconds when the
On/Off switch 10 is pressed halfway or fully.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Slow flashing 1 x green
The 3 LEDs of the battery charge-control indica-
tor 8 and the Power Light 7 flash rapidly when
the battery temperature is not within the opert-
ing temperature range of –10 to +70°C.
Temperature Dependent Overload Protection
When using as intended for, the power tool can-
not be subject to overload. When the load is too
high or the allowable battery temperature of
70 °C is exceeded, the electronic control switch-
es off the power tool until the temperature is in
the optimum temperature range again.
The 3 LEDs of the battery charge-control indica-
tor 8 and the "Power light" 7 flash rapidly when
the battery temperature is not within the operat-
ing temperature range of –10 to +70°C and/or
when the overload protection has actuated.
Protection Against Deep Discharging
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.

Working Advice

Apply the power tool to the screw only when
it is switched off. Rotating tool inserts can
slip off.
Tips
After longer periods of working at low speed, al-
low 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 sharp-
ened HSS drill bits (HSS=high-speed steel). The
appropriate quality is guaranteed by the Bosch
accessories program.
Before screwing larger, longer screws into hard
Capacity
materials, it is advisable to predrill a pilot hole
with the core diameter of the thread to approx.
≥ 71%

Maintenance and Cleaning

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.
For safe and proper working, always keep
the machine and ventilation slots clean.
When the battery is no longer operative, please
refer to an authorised after-sales service agent
for Bosch power tools.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article number
given on the type plate of the machine.
