The LED (8) lights up when the on/off switch (10) is lightly
or fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (10).
LED worklight with status indicator
The LED worklight (8) is used as a status indic-
ator for device protection and low battery
status:
LED Description
Feedback
Flashing light 3x Battery status is low.
during operation The voltage level of the battery has fallen
below the optimum value. The perform-
ance of the device is restricted.
Flashing light 3x Device protection is active.
during downtime Device protection has been activated to
prevent the battery from consuming a
large amount of power and to protect the
device against damage.
– If the battery status is low, charge the battery (6) or re-
place the weak battery with a fully charged battery.
Adjusting the speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (10) to varying extents.
A light pressure on the on/off switch (10) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Preselecting torque (applies to screwdriving mode)
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 tool will stop delivering power to the applica-
tion.
Mechanical gear selection
Only operate the gear selector (5) when the power
u
tool is not in use.
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.
Always push the gear selector switch as far as it will
u
go. Otherwise, the power tool may become damaged.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the battery tem-
perature is not kept within the permitted range, the power
tool switches off and the LED on the power tool flashes. Al-
low the power tool to cool down before you carry on work-
ing.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder (1), are
locked when the on/off switch (10) is not pressed.
Bosch Power Tools
This enables screws to be screwed in even when the battery
(6) is empty and allows the power tool to be used as a
screwdriver.
Practical advice
Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
Before screwing larger, longer screws into hard materials, it
is advisable to pre-drill a pilot hole with the core diameter of
the thread to approx. 2/3 of the screw length.
An auxiliary tool can be used to remove the screwdriver bit
or universal bit holder.
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.
