Certain dusts, such as oak or beech dust, are
considered as carcino genic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
4.- Operation
4.1.- Starting Operation
→ Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
When operating the machine with power from
mobile generators that do not have sufficient re-
serve capacity or are not equipped with suitable
voltage control with starting current amplifica-
tion, loss of performance or untypical behavior
can occur upon switching on.
Please observe the suitability of the power gen-
erator being used, particularly with regard to
the mains voltage and frequency.
Switching On and Off
To start the power tool, push the On/Off switch
3 forwards.
To lock the On/Off switch 3, press the On/Off
switch 3 down at the front until it latches.
To switch off the power tool, release the On/Off
switch 3 or, if it is locked, briefly push down the
back of the On/Off switch 3 and then release it.
→ Check grinding tools before using. The
grinding tool must be mounted properly
and be able to move freely. Carry out a test
run for at least one minute with no load. Do
not use damaged, out-of-centre or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.

4.2.- Working Advice
→ Exercise caution when cutting slots in
structural walls; see Section "Information
on Structures ".
→
Clamp the workpiece if it does not remain
stationary due to its own weight.
→ Do not strain the machine so heavily that it
comes to a standstill.
→
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Rough Grinding
→
Never use a cutting disc for roughing.
The best roughing results are achieved when
setting the machine at an angle of 30° to 40°.
Move the machine back and forth with moderate
pressure. In this manner, the workpiece will not
become too hot, does not discolour and no
grooves are formed.
Cutting Metal
When cutting, work with moderate feed, adapt-
ed to the material being cut. Do not exert pres-
sure onto the cutting disc, tilt or oscillate the
machine.
Do not reduce the speed of running down cut-
ting discs by applying sideward pressure.
When cutting profiles and square bar, it is best
to start at the smallest cross section.
Cutting Stone
→ The machine may be used only for dry cut-
ting/grinding.
For cutting stone, it is best to use a diamond
cutting disc.
Switch on the ma
the cutting guide on the workpiece.
Slide the machine with moderate feed, adapted to
the material to be worked.

The machine must
always work in an
up-grinding mo-
tion. Otherwise,
the danger exists
of it being pushed
uncontrolled out
of the cut.
