Cutting Metal
For cutting with bonded abrasives, always use the pro-
tection guard for cutting 14.
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.
When cutting profiles and square bar, it is best to start at the
smallest cross section.
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 21, the vacuum cleaner must be approved for vacuum-
ing masonry dust. Suitable vacuum cleaners are available
from Bosch.
For cutting expecially hard material, e. g., concrete with high
pebble content, the diamond cutting disc can overheat and
become damaged as a result. This is clearly indicated by cir-
cular 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.
Bosch Power Tools
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.

cut.
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 conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD). When work-
ing metals, conductive dust can settle in the interior of the
power tool. The total insulation of the power tool can be im-
paired.
Please store and handle the accessory(-ies) carefully.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
