Observe the relevant regulations in your country for the materi-
als to be worked.
Avoid dust accumulation at the workplace. Dust
r
can easily ignite.
Operation
Start-up
Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Insert the charged battery (4) into the handle of the power
tool until you feel it engage and it is flush with the handle.
Switching on/off
To start the power tool, push the on/off switch (3) forward.
To lock the on/off switch (3) in position, push the on/off
switch (3) forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (3);
or, if the switch is locked, briefly push the on/off switch (3)
backward and down and then release it.
Always check abrasive tools before using them.
r
The 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 ab-
rasive tools that are damaged, run untrue or vi-
brate during use. Damaged abrasive tools can burst
apart and cause injuries.
Temperature monitoring/overload protection
indicator
The red LED indicator (6) helps you to protect the battery
against overheating and the motor against overload.
If the LED indicator (6) is lit up permanently in red, the
temperature of the battery is too high and the power tool
switches off automatically.
– Switch the power tool off.
– Allow the battery to cool down before you carry on work-
ing.
If the LED indicator (6) is flashing red, then the power tool
is blocked and will switch off automatically.
Pull the power tool out of the workpiece.
The power tool will continue to work as soon as the blockage
is rectified.
Practical advice
Exercise caution when cutting slots in structural
r
walls; see the "Information on structural design"
section.
When cutting lightweight materials, take into
r
account the statutory provisions and recom-
mendations of the material manufacturer.
Clamp the workpiece if it is not secure under its
r
own weight.
Do not load the power tool so heavily that it
r
comes to a stop.
If the power tool has been subjected to a heavy
r
load, 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.
r
Do not touch grinding and cutting discs until
r
they have cooled down. The discs can become very
hot while working.
If the power tool becomes electrostatically charged, the built-in
electronics will switch the power tool off. Press the on/off
switch (3) again to restart the power tool.
Rough grinding
Never use cutting discs for rough grinding.
r
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 be-
come too hot or discolour and that grooves are not formed.
Cutting metal
Always use the protective guard for cutting (10)
r
when 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.
The power tool must always work in an up-grinding motion.
Otherwise there is a risk that it will be pushed uncontrolled
out of the cut.
For best results when cutting profiles and rectangular tubing,
start at the smallest cross section.
Cutting Stone
Provide sufficient dust extraction when cutting
r
stone.
Wear a dust mask.
r
The power tool may be used only for dry cut-
r
ting/grinding.
For cutting stone, it is best to use a diamond cutting disc.
When cutting especially hard materials such as concrete with
a high pebble content, the diamond cutting disc can overheat
and become damaged as a result. This is clearly indicated by
circular sparking, rotating with the diamond cutting disc.
