Switching On and Off
To start the machine, press the On/Off switch 13 and keep it
pressed.
The LED 10 lights up when the On/Off switch 13 is halfway or
fully pressed, and enables illumination of the screwing loca-
tion in unfavourable light conditions.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 13 is
pressed.
Light pressure on the On/Off switch 13 results in a low rota-
tional speed. Further pressure on the switch results in an in-
crease in speed.
Setting the torque
With the torque preselection ring 3, the required torque can
be preselected in 20 steps. The inserted tool is stopped as
soon as the set torque is reached.
Gear selection, mechanical
The gear selector 5 can be actuated at standstill or
when the machine is running. However, this should not
be done while operating at full load or maximum speed.
1st gear:
Low speed range; for working with large drilling diameters.
2nd gear:
High speed range; for drilling with small drilling diameter.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted operating temperature range, the speed is re-
duced. The power tool will not run at full speed again until the
permitted operating temperature has been reached.
Activation of the temperature-controlled overload protector
is indicated by the LED 10 on the power tool lighting up red.
To reach the permitted operating temperature range again,
either switch the gear selector 5 to gear 1, run the power tool
at no load or wait until the LED 10 extinguishes. When the LED
10 has extinguished, the tool has reached the permitted op-
erating temperature range again.
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.
Rapid Shut-off
The rapid shut-off feature enables better control of the power
tool. The power tool shuts off in case of sudden and unexpect-
ed rotation of the power tool around the drilling axis.
The rapid shut-off feature is indicated by a flashing LED on the
power tool.
To restart the machine, release the On/Off switch and then
actuate again.

Rapid shut-off can trigger only when the power tool is
running at maximum operating speed and can rotate
freely around the drill bit axis. Choose a suitable work
position for this. Otherwise, rapid shut-off will not be en-
sured.
Connectivity functions
In conjunction with the Bluetooth® Low Energy Module
GCY 30-4 (accessory), the following connectivity functions
are available for the power tool:
– Registration and personalisation
– Status check, output of warning messages
– General information and settings
– Management
Read the corresponding operating instructions for informa-
tion about the Bluetooth® Low Energy Module GCY 30-4.
Working Advice
The power tool with inserted Bluetooth® Low Energy
Module GCY 30-4 (accessory) is equipped with a radio
interface. Local operating restrictions, e.g. in aircraft
or hospitals, must be observed.
Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
An auxiliary tool can be used to remove the screwdriver bit or
universal bit holder.
Belt Clip
With the belt clip 6, the machine can be hung onto a belt. The
user has both hands free and the machine is always at hand.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
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.
