Working Advice

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.
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 pro-
tection guard for cutting 12.
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.

Cutting disc and cutting guide
(Cutting masonry/stone is permitted
only with use of the cutting guide)
Do not reduce the speed of running down cut-
ting discs by applying sideward pressure.
Cutting Stone
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 19.
The machine may be used only for dry cut-
ting/grinding.
For cutting stone, it is best to use a diamond
cutting disc. As a safety measure against jam-
ming, the cutting guide with dust extraction pro-
tection guard 19 must be used.
Operate the machine only with dust extraction
and additionally wear a dust protection mask.
The vacuum cleaner must be approved for the
extraction of masonry dust. Bosch provides suit-
able vacuum cleaners.

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.
