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 connection of the power tool with the app must be con-
firmed by pressing the speed preselection button (26) on
the user interface (4). The app requests this when connect-
ing.
Practical advice
u The power tool with inserted Bluetooth
®
Low Energy
Module GCY42 is equipped with a radio interface.
Local operating restrictions, e.g. in aircraft or hospit-
als, 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.
u Exercise caution when cutting slots in structural walls;
see the "Information on structural design" section.
u Clamp the workpiece if it is not secure under its own
weight.
u Do not load the power tool so heavily that it comes to a
stop.
u If the power tool has been subjected to a heavy load,
continue to run it at no-load for several minutes to
cool down the accessory.
u Do not use the power tool with a cut-off stand.
u Do not touch grinding and cutting discs until they have
cooled down. The discs can become very hot while work-
ing.
If the power tool becomes electrostatically charged, the
built-in electronics will switch the power tool off. Press the
on/off switch (5) again to restart the power tool.
Rough grinding
u Never use cutting discs for rough grinding.
The best rough grinding results are achieved with a set angle
of 30° to 40°. Move the power tool back and forth with mod-
erate pressure. This will ensure that the workpiece does not
become too hot or discolour and that grooves are not
formed.
Flap disc
The flap disc (accessory) enables you to machine curved
surfaces and profiles.
Flap discs have a considerably longer service life, lower
noise levels and lower sanding temperatures than conven-
tional grinding discs.
Cutting metal
u Always use the protective guard for cutting (12) when
cutting bonded abrasives.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
