Bosch Power Tools
Practical
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, continue to run
it at no-load for several minutes to cool down the acces-
sory.
Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Do not use the power tool with a cut-off stand.
When the power tool is electrostatically charged, the built-in
electronic control switches it off. To restart the power tool,
press the On/Off switch

again.
Rough Grinding
Never use a cutting disc for roughing.
The best roughing results are achieved when setting the ma-
chine 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 temperatures than conventional
sanding sheets.
Cutting Metal
For cutting with bonded abrasives, always use the
protect
ive
guard for cutting 1
3
.
When cutting, work with moderate feed, adapted to the mate-
rial being cut. Do not exert pressure onto the cutting disc, tilt
or oscillate the machine.
Do not reduce the speed of running down cutting discs by ap-
plying sideward pressure.
The machine must al-
ways work in an up-
grinding motion. Other-
wise, the danger exists
of it being pushed un-
controlled out of the
cut.
When cutting profiles
and square bar, it is best
to start at the smallest
cross section.
Cutting Stone (see
figure
B
)
Provide for sufficient dust extraction when cutting
stone.
Wear a dust respirator.
The machine may be used only for dry cutting/grinding.
For cutting stone, it is best to use a diamond cutting disc.
When using the cutting guide with dust extraction protection
guard 2
5
, the vacuum cleaner must be approved for vacuum-
ing masonry dust. Suitable vacuum cleaners are available
from Bosch.
Switch on the machine
and place the front part
of the cutting guide on
the workpiece. Slide the
machine with moderate
feed, adapted to the ma-
terial to be worked.
For cutting especially hard material, e. g., concrete with high
pebble content, the diamond cutting disc can overheat and
become damaged as a result. This is clearly indicated by cir-
cular sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and allow the dia-
mond cutting disc to cool by running the machine for a short
time at maximum speed with no load.
Noticeably decreasing work progress and circular sparking
are indications of a diamond cutting disc that has become
dull. Briefly cutting into abrasive material (e.
g. lime-sand
brick) can resharpen the disc again.
