Practical Advice

With the Bluetooth® Low Energy Module GCY 42, the
u
power tool is equipped with a radio interface. Local
operating restrictions, e.g. in aircraft or hospitals,
must be observed.
In areas in which the Bluetooth® wireless technology
u
must not be used, the Bluetooth® Low Energy Module
GCY 42 and the coin cell must be removed.
Note: The cover (15) can only be closed securely if the
Bluetooth® Low Energy Module GCY 42 and the coin cell are
in the power tool.
– To deactivate the Bluetooth® Low Energy Module
GCY 42, turn the coin cell over or place a means of insula-
tion between the coin cell and Bluetooth® Low Energy
Module GCY 42.
– Close the cover (15) to prevent dirt from getting in.

Rapid shut-off (KickBack Control)
– To switch the tool back on, release the on/off switch (9)
Electronic Precision Control (EPC)
EPC assists you when drilling and when working with impact
in sensitive materials by ensuring slow start-up of the operat-
ing speed for precise working.
If the application tool jams or snags, the power trans-
mission to the drill spindle will be interrupted. Always
hold the power tool firmly with both hands to with-
stand the forces this may create and adopt a position
with stable footing.
Switch the power tool off immediately and remove the
application tool if the power tool becomes blocked.
Switching on when the drilling tool is blocked may
cause high torque reactions.
The rapid shut-off function (KickBack
Control) gives the user greater control
over the power tool and offers them bet-
ter protection than power tools that do
not have Kickback Control. If the power
tool suddenly and unforeseeably rotates
around the drilling axis, it will switch off,
the rapid shut-off indicator (17) will light
up red and the worklight (11) will flash.
When rapid shut-off is activated, the
status indicator (20) flashes red.
and then press it again.
