Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (14) to varying extents.
A light pressure on the on/off switch (14) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Pre-selecting the torque
The torque presetting ring (3) can be used to pre-select the
required torque in 20 stages. Once the set torque has been
reached, the application tool will be stopped.
Mechanical gear selection
You can press the gear selector switch (5) with the
u
power tool off or on. You should not do this at full load
or maximum torque, however.
First gear:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Second gear:
High speed range; for working with a small drilling diameter.
Temperature-dependent overload protection
When used as intended, the power tool cannot be over-
loaded. In the event of heavy loading or the temperature
rising/falling outside the permitted battery temperature
range, the speed will be reduced. The power tool will not run
at full speed again until the permitted battery temperature
has been reached.
Activation of the temperature-controlled overload protector
is indicated by the LED (11) on the power tool lighting up
red. The LED (11) will go out once the temperature of the
tool's battery is back within the permissible range.
Protection against deep discharge
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Emergency switch-off (KickBack Control)
The emergency switch-off function (Kick-
Back Control) gives the user greater control
over the power tool and offers them better
protection than power tools that do not
have KickBack Control. The power tool will switch off if it
suddenly and unforeseeably rotates around the drilling
axis.
Rapid shut-off is indicated by the LED on the power tool
flashing.
To switch the tool back on, release the on/off switch and
then press it again.
If the KickBack Control function is defective, it will no
u
longer be possible to switch the power tool on. Have
the power tool serviced by a qualified repair person
using only original replacement parts.
Bosch Power Tools
Practical advice
Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
An auxiliary tool can be used to remove the screwdriver bit
or universal bit holder.
Belt clip
You can use the belt clip to hang the power tool on a belt, for
example. You then have both hands free and the power tool
is always at hand.
Colour clip (see figure D)
You can use the coloured clip (6) to individually identify the
power tool.
Maintenance and Service
Maintenance and Cleaning
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
