To attach the grinding/cutting disc, screw in the clamping
bolt with washer (11). Tighten the bolt using the hex
key (13) until the washer of the bolt is flush with the grind-
ing/cutting disc (12) (see figure C3).
Then push the spindle lock button (2) back again
(see figure C4).
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [min
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.

Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.

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. 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.
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 walls;
u
see the "Information on structural design" section.
When cutting lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturer.
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.
