Cutting Metal
For cutting metal, always work with the pro-
tection guard for cutting 13.
When cutting, work with moderate feed, adapt-
ed to the material being cut. Do not exert pres-
sure onto the cutting disc, tilt or oscillate the
machine.
Do not reduce the speed of running down cut-
ting discs by applying sideward pressure.
Cutting Stone
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 20.
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 20 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.
Bosch Power Tools
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-

the machine for a short time at maximum speed

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
machine when working with metal. The pro-
tective insulation of the machine can be de-
graded. The use of a stationary extraction
