Cutting Grinder Stand
With the cutting grinder stand 17 (accessory),
work pieces of the same length can be cut at an-
gles of 0 to 45°.
When cutting profiles and square pipes, it is best
to start with the smallest cross section.
Cutting Stone
The machine must be used only for dry
cutting/grinding.
Operate the machine with dust extraction only. In
addition, wear a dust mask.
Slide the machine with moderate feed, adapted
to the material to be worked (Figure).
For cutting especially 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 spark-
ing, rotating with the diamond cutting disc.

The direction in
which the cutting is
performed is impor-
tant.
The machine must
always work in an
up-grinding motion.
Therefore, never
move the machine in
the other direction!
Otherwise, the dan-
ger exists of it being
pushed uncon-
trolled out of the cut.
It is best to use a dia-
mond cutting disc. As
a safety measure
against jamming, use
the cutting guide 20
with the special dust
extraction protection
guard.
The vacuum cleaner
must be approved for
the extraction of ma-
sonry dust.
Bosch provides suit-
able vacuum clean-
ers.
Switch on the ma-
chine and place the
front part of the cut-
ting guide on the
workpiece.

In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
freely at no-load speed for a short time.
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.
Rotating the Machine Head
Before any work on the machine itself, pull
the mains plug.
guide 20/cutting grinder stand 17 (accessory) or
for left-handed persons.
Unscrew completely the four screws.
Rotate the machine head carefully and without
removing from the housing to the new position.
Screw in the screws again and tighten.
Maintenance and Cleaning
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The
protective insulation of the machine can be
degraded. The use of a stationary extrac-
tion system is recommended in such cases
as well as frequently blowing out the venti-
lation slots and installing a residual current
device (RCD).
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order number
given on the nameplate of the machine.
The machine head
can be rotated with
respect to the ma-
chine housing in 90°
steps. In this manner,
the On/Off switch
can be brought to an
advantageous han-
dling position for spe-
cial working situa-
tions, e. g., for cutting
work with the cutting
