Soft
operating mode is used to machine delicate materials.
– "Hammer drilling" operating mode: EPC active, slow increase in speed for soft starts up to
80 % of the maximum speed for hammer drilling in sensitive surfaces
– "Chiselling" operating mode: Adaptive Speed Control with an even more sensitive setup
– Rapid shut-off (KickBack control) with an even more sensitive setup
lights up
In
Favorite
working mode, the power tool can be individually configured via a smartphone
app.
– "Hammer drilling" operating mode can be configured in several steps:
Power via speed
Electronic Precision Control (EPC) via start-up speed
– "Chiselling" operating mode: Adaptive Speed Control can be switched on and off
– Sensitivity of rapid shut-off (KickBack control) until switch-off can be configured
Connectivity functions
In conjunction with the
Bluetooth
® Low Energy Module
GCY 42
, 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 42
.
The smartphone indicator
(28)
lights up if the power tool
sends information (e.g. a temperature warning) to a mobile
device via
Bluetooth
® wireless technology.
Practical Advice
u
With the
Bluetooth
®
Low Energy Module GCY 42, the
power tool is equipped with a radio interface. Local
operating restrictions, e.g. in aircraft or hospitals,
must be observed.
u
In areas where the
Bluetooth
®
wireless technology is
not allowed to be used, the
Bluetooth
®
Low Energy
Module GCY 42 and the button cell must be removed
.
Note:
The cover
(13)
can only be securely closed if the
Bluetooth
® Low Energy Module GCY 42 and the button cell
are situated in the power tool.
– To
deactivate
the
Bluetooth
® Low Energy Module
GCY 42, rotate the button cell or place means of insula-
tion between the button cell and
Bluetooth
® Low Energy
Module GCY 42.
– Close the cover
(13)
to prevent dirt from getting in.
Setting the drilling depth (see figure J)
You can use the depth stop
(17)
to set the required drilling
depth
X
.
– Press the button for depth stop adjustment
(15)
and in-
sert the depth stop into the auxiliary handle
(16)
.
The fluting on the depth stop
(17)
must face downwards.
– Insert the SDS-plus application tool into the SDS-plus tool
holder
(3)
to the stop. Otherwise, the movability of the
SDS-plus drilling tool can lead to incorrect adjustment of
the drilling depth.
– Pull the depth stop far enough out that the distance
between the drill bit tip and the edge of the depth stop
corresponds to the required drilling depth
X
.
Overload clutch
u
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.
u
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.
Rapid shut-off (KickBack Control)
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
and the rapid shut-off indicator
(24)
will
light up and the worklight
(14)
will flash.
When rapid shut-off is activated, the
status indicator
(27)
flashes red.
– To
switch the tool back on
, release the on/off switch
(11)
and then press it again.
Electronic Precision Control (EPC)
EPC assists you when working with impact in sensitive ma-
terials by ensuring slow start-up and reduced operating
speed.
