Cutting
When cutting, do not press, jam or
oscillate the machine. Work with
moderate feed, adapted to the ma-
terial being machined.
Do not reduce the speed of running
down cutting discs by applying
sideward pressure.
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.
Grinder Stand
With the grinder stand 29 (accessory), work-
pieces can be cut at angles of 0 to 45° at the
same lengths.
The safety notes and operating instructions in the
respective operating instructions manual of the
angle grinder are to be strictly observed. Use only
original Bosch grinder stands.
Cutting Stone
■ The machine must be used only for dry
cutting/grinding.
It is best to use a dia-
mond cutting disc. As
a safety measure
against jamming, use
the cutting guide 26
with the special dust
extraction protection
guard.
Operate the machine with dust extraction only. In
addition, wear a dust mask.
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.
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
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
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.
