When operating the machine with power from
mobile generators that do not have sufficient
reserve capacity or are not equipped with suit-
able voltage control with starting current ampli-
fication, 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
2 forwards.
To lock the On/Off switch 2 , press the On/Off
switch 2 down at the front until it latches.
To switch off the power tool, release the
On/Off switch 2 or, if it is locked, briefly push
down the back of the On/Off switch 2 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.

Working advice

� � � � Exercise caution when cutting slots in
structural walls; see Section "Informa-
tion 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.

Brushing, rust removal Cup brush, sanding disc

Desbastar Disco abrasivo
Cutting disc and cutting guide
(Cutting masonry/stone is permitted
Cutting only with use of the cutting guide)
� � � � After heavily straining the power tool,
continue to run it at no-load for several
minutes to cool down the cutting/grind-
ing tool.
� � � � Grinding and cutting discs become very
hot while working; do not touch until
they have cooled.
� � � � Do not use the power tool with a cut-off
stand.
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 moder-
ate pressure. In this manner, the workpiece will
not become too hot, does not discolour and no
grooves are formed.
Flap disc
With the flap disc (accessory), curved surfaces
and profiles can be worked.
Flap discs have a considerably higher service
life, lower noise levels and lower sanding tem-
peratures than conventional sanding sheets.
Cutting metal
� � � � For cutting metal, always work with the
protection guard for cutting 12.
When cutting, work with moderate feed,
adapted to the material being cut. Do not exert
pressure onto the cutting disc, tilt or oscillate
the machine.
Do not reduce the speed of running down cut-
ting discs by applying sideward pressure.
