Cutting Stone
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 18.
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 18 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
cutting 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
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.
