Operation
Start-up
►Pay attention to the mains voltage. The
voltage of the power source must match
the voltage specifi ed on the rating plate of
the power tool.
►Hold the tool by the insulated gripping
surfaces and auxiliary handle only. The
application tool could come into contact
with hidden wiring or its own cord. Con-
tact with live wires may make metal parts of
the tool live, posing a risk of electric shock.
When operating the power tool using a mobile
generator that does not have sufficient re-
serve capacity or an adequate voltage control
system with inrush current boost converter,
loss of performance or atypical behavior may
occur upon switch-on.
Please check the suitability of the power gen-
erator you are using, particularly with regard
to the mains voltage and frequency.
Switching on/off
To start the power tool, push the on/off switch
forward. To lock the on/off switch in position,
push the on/off switch forward and down until
it clicks into place.
To switch off the power tool, release the on/off
switch; or, if the switch is locked, briefl y push
the on/off switch backward and down and
then release it.
► Always check abrasive tools before us-
ing them. The abrasive tool must be fi tted
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.
► The rated speed of the accessory must
be at least equal to the maximum speed
marked on the power tool. Accessories run-
ning faster than their rated speed can break
and fl y apart.
Working Advice
► Pull the plug out of the socket before
carrying out any work on the power tool.
►Exercise caution when cutting slots in
structural walls;
►Clamp the workpiece if it is not secure
under its own weight.
►Do not load the power tool so heavily
that it comes to a stop.
►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 ac-
cessory.
►Do not use the power tool with a cut-off
stand.
► Do not touch grinding and cutting discs
until they have cooled down. The discs can
become very hot while working.
Rough grinding
►
Always use the protective guard when
grinding.
► 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 moderate
pressure. This will ensure that the workpiece
does not become too hot or discolor and that
grooves are not formed.
Flap Disc
With the flap disc, curved surfaces and pro-
fi les can be worked. Flap discs have a consid-
erably higher ser- vice life, lower noise levels
and lower sanding temperatures than conven-
tional sanding sheets.
Cutting Metal
► Always use the protective guard 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.
Do not attempt to reduce the speed of a cut-
ting disc coming to a stop by applying pres-
sure 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 profi les and
rectangular tubing, start at the smallest cross
section.
Cutting stone
►Provide sufficient dust extraction when
cutting stone.
►Wear a dust mask.
►The power tool may be used only for dry
cutting/grinding.
For best results when cutting stone, use a di-
amond cutting disc.
Maintenance and Cleaning
►
Before any work on the machine itself (e.
g. maintenance, tool change, etc.) as well
as during transport and storage, remove
the battery from the power tool. There is
danger of injury when unintentionally actuat-
ing the On / Off switch.
► For safe and proper working, always
keep the machine and ventilation slots
clean.
