Practical advice

With the GCY 30-4 Bluetooth
u
power tool is equipped with a radio interface. Local
operating restrictions, e.g. in aircraft or hospitals,
must be observed.
Exercise caution when cutting slots in structural walls;
u
see the "Information on structures" section.
Clamp the workpiece if it is not secure under its own
u
weight.
Do not load the power tool so heavily that it comes to a
u
stop.
If the power tool has been subjected to a heavy load,
u
continue to run it at no-load for several minutes to
cool down the accessory.
Do not use the power tool with a cut-off stand.
u
Do not touch grinding and cutting discs until they have
u
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 (6) again to restart the power tool.
Rough grinding
Never use cutting discs for rough grinding.

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-

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.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.

Solution
Run the power tool at no load and allow it to
cool down
Leave the power tool to cool down
Solution
–
Run the power tool at no load and allow it to
cool down, or replace or charge the battery
soon
Allow the power tool to cool down, or replace
or charge the battery
Turn the power tool off and on again
–
Always use the protective guard for cutting (16) when
cutting bonded abrasives.
The power tool must always
work in an up-grinding mo-
tion. Otherwise there is a
risk that it will be pushed
uncontrolled out of the cut.
For best results when cut-
ting profiles and rectangular
tubing, start at the smallest
cross section.
Cutting Stone (see figure
Provide sufficient dust extraction when cutting stone.
Wear a dust mask.
