Cutting Metal
For cutting with bonded abrasives, always use the pro-
tection guard for cutting 13.
When cutting, work with moderate feed, adapted to the mate-
rial being cut. Do not exert pressure onto the cutting disc, tilt
or oscillate the machine.
Do not reduce the speed of running down cutting discs by ap-
plying sideward pressure.
Cutting Stone
Provide for sufficient dust extraction when cutting
stone.
Wear a dust respirator.
The machine may be used only for dry cutting/grinding.
For cutting stone, it is best to use a diamond cutting disc.
When using the cutting guide with dust extraction protection
guard 20, the vacuum cleaner must be approved for vacuum-
ing masonry dust. Suitable vacuum cleaners are available
from Bosch.
aged as a result. This is clearly indicated by circular sparking,
rotating with the diamond cutting disc.
In this case, interrupt the cutting process and allow the dia-
mond cutting disc to cool by running the machine for a short
time at maximum speed with no load.
Noticeable decreasing work progress and circular sparking
are indications of a diamond cutting disc that has become
dull. Briefly cutting into abrasive material (e. g. lime-sand
brick) can resharpen the disc again.
