Setting the torque
The required torque can be preselected in 25 steps with the
torque preselection ring 3. With the correct setting, the insert
tool is stopped as soon as the screw is screwed flush into the
material or when the set torque is reached.
Select a higher setting when driving out screws, or set to the
symbol “Drilling”.
Drilling
The safety clutch is deactivated in the “Drilling” position.
Gear selection, mechanical
Actuate the gear selector 4 only when the machine is at
a standstill.
Two speed ranges can be preselected with the gear selector
4
.
Gear I:
Low speed range; for screwdriving or working
with large drilling diameter.
Gear II:
High speed range; for working with small drilling
diameter.
If the gear selector
4
cannot be fully engaged, lightly rotate
the drive spindle with the drill bit by twisting the drill chuck.
Switching On and Off
To save energy, only switch the power tool on when using it.
To
start
the machine, press the On/Off switch
11
and keep it
pressed.
The power light
8
lights up when the On/Off switch
11
is
slightly or completely pressed, and allows the work area to be
illuminated when lighting conditions are insufficient.
To
switch off
the machine, release the On/Off switch
11
.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch
11
is
pressed.
Light pressure on the On/Off switch
11
results in a low rota-
tional speed. Further pressure on the switch results in an in-
crease in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch
11
is not pressed, the drill spindle
and thus the tool holder are locked.
This enables screws to be screwed in, even when the battery is
empty and allows for the machine to be used as a screwdriver.
Run-on Brake
When the On/Off switch
11
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 release the On/Off switch
11
.
By doing so, the head of the screw does not penetrate into the
material.
Battery Charge-control Indication
The battery charge-control indicator
9
consists of three green
LEDs, and indicates the charge condition of the battery for a
few seconds when the On/Off switch
11
is pressed halfway or
fully.
The 3 LEDs of the battery charge-control indicator
9
and the
Power Light
8
flash rapidly when the battery temperature is
not within the operating temperature range of –10 to +70 °C.
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 temperature is in the op-
timum temperature range again.
The 3 LEDs of the battery charge-control indicator
9
and the
“Power light”
8
flash rapidly when the battery temperature is
not within the operating temperature range of –10 to +70 °C
and/or when the overload protection has actuated.
Protection Against Deep Discharging
The Lithium-Ion battery is protected against deep discharging
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.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed 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
Before any work on the machine (e. g., maintenance,
tool change, etc.) as well as during transport and stor-
age, set the rotational direction 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 ventilation slots clean.
When the battery is no longer operative, please refer to an au-
thorised after-sales service agent for Bosch power tools.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
