To switch off the power tool, release the on/off switch (4);
or, if the switch is locked, briefly push the on/off switch (4)
backward and down and then release it.
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.

The values specified for speed levels are guide values.
The rated speed of the accessory must be at least
u
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed
can break and fly apart.

Practical advice

Exercise caution when cutting slots in structural walls;
u
see the "Information on structural design" 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.
Rough grinding
Never use cutting discs for rough grinding.
u
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.

To restart the tool, set the on/off switch (4) to the off posi-
tion and then switch the power tool on again.
Constant Electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
Soft start
The electronic soft start limits the torque when the power
tool is switched on and increases the service life of the mo-
tor.
Speed preselection
You can select the required speed using the speed preselec-
tion thumbwheel (7), even during operation. The informa-
tion in the table below describes the recommended values.
Application tool
Sanding pad with sanding sheet 2−3
Cup brush, abrasive disc
Grinding disc
Grinding disc
Cutting disc
Diamond cutting disc and cutting
guide (cutting of stone is permit-
ted only with a cutting guide)
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
Always use the protective guard for cutting (13) when
u
cutting with 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.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.
Cutting Stone (see figure A)
Provide sufficient dust extraction when cutting stone.

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.
