Cutting metal
Always use the protective guard for cutting (13)/(29)
when cutting bonded abrasives.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.
Provide sufficient dust extraction when cutting stone.
u
Wear a dust mask.
u
The power tool may be used only for dry cutting/grind-
u
ing.
For best results when cutting stone, use a diamond cutting
disc.
When using the extraction guard for cutting with a guide
block (21), the vacuum cleaner must be approved for vacu-
uming stone dust. Suitable vacuum cleaners are available
from Bosch.
crete with a 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 dia-
mond cutting disc.
If this happens, stop cutting and allow the diamond cutting
disc to cool down by running the power tool for a short time
at maximum speed with no load.
Working noticeably slower and with circular sparking indic-
ate that the diamond cutting disc that has become dull. You
can resharpen the disc by briefly cutting into abrasive mater-
ial (e.g. lime-sand brick).

The power tool must always
work in an up-grinding mo-
tion. Otherwise, there is a
risk that it will be pushed
uncontrolled out of the cut.
For best results when cut-
ting profiles and rectangular
tubing, start at the smallest
cross section.
Cutting stone
Switch on the power tool
and position it with the
front part of the guide block
on the workpiece. Move the
power tool with a moderate
feed motion that is suited to
the material being ma-
chined.
When cutting especially
hard materials such as con-

sponsible structural engineer, architect or construction su-
pervisor before starting work.

Maintenance and Service

Maintenance and cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In extreme conditions, always use a dust extractor if
u
possible. Blow out ventilation slots frequently and in-
stall a residual current device (RCD) upstream. When
machining metals, conductive dust can settle inside the
power tool, which can affect its protective insulation.
Store and handle the accessories carefully.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
