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.
After heavily straining the power tool, con-
tinue to run it at no-load for several minutes
to cool down the cutting/grinding tool.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Note: When not using for extended periods, pull
the mains plug out of the socket outlet. When
the mains plug is inserted and mains voltage is
given, the power tool, even when switched off,
still consumes a low amount of current.
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.
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
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.
Bosch Power Tools
Cut Off Stand
The cut off stand (accessory) allows for cutting
workpieces to size at angles from 0° to 45°.
Strictly observe the safety warnings and work-
ing instructions in the operating instructions of
the cut off stand. Use only original Bosch cut off
stands.
Cutting Stone
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 20.
The machine may be used only for dry cut-
ting/grinding.

The machine must
always work in an
up-grinding mo-
tion. Otherwise,
the danger exists
of it being pushed
uncontrolled out
of the cut.
When cutting pro-
files and square
bar, it is best to
start at the small-
est cross section.
