Cut Off Stand (Accessory)
The cut off stand (accessory) allows for cutting
workpieces to size at angles from 0° to 45°.
Note: The cut off stand 19 may only be used for
cutting discs with a maximum diameter of
230 mm. The safety notes and operating instruc-
tions in the respective instruction manual of the
cut off stand are to be strictly observed. Use on-
ly original Bosch cut off stands.
Cutting Stone (see figure A)
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 17.
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 17 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.

For cutting expecially hard material, e. g., con-
crete with high pebble content, the diamond cut-
ting disc can overheat and become damaged as
a result. This is clearly indicated by circular
sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
19
the machine for a short time at maximum speed
with no load.
Noticeable decreasing work progress and circu-
lar sparking are indications of a diamond cutting
disc that has become dull. Briefly cutting into
abrasive material (e. g. lime-sand brick) can re-
sharpen the disc again.
Information on Structures
Slots in structural walls are subject to the Standard
DIN 1053 Part 1, or country-specific regulations.
These regulations are to be observed under all
circumstances. Before beginning work, consult
the responsible structural engineer, architect or
the construction supervisor.

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
In extreme working conditions, conductive
dust can accumulate in the interior of the ma-
chine when working with metal. The protec-
tive insulation of the machine can be degrad-
ed. The use of a stationary extraction system
is recommended in such cases as well as fre-
quently blowing out the ventilation slots and
installing a residual current device (RCD).
Switch on the ma-
chine and place
the front part of
the cutting guide
on the workpiece.
Slide the machine
with moderate
feed, adapted to
the material to be
worked.
