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.
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
f
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
materials, it is advisable to predrill a pilot hole
with the core diameter of the thread to approx.
2
/
3
of the screw length.
Maintenance and Service
Maintenance and Cleaning
f
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.
f
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.
