For cutting stone, it is best to use a diamond cut-
ting disc. As a safety measure against jamming,
the cutting guide with dust extraction protection
guard 20 must be used.
Operate the power tool only with dust extraction
and additionally wear a dust protection mask.
The vacuum cleaner must be approved for the ex-
traction of masonry dust. Bosch provides suit-
able vacuum cleaners.
Switch on the pow-
er tool and place
the front part of the
cutting guide on the
workpiece. Move
the power tool with
moderate feed,
adapted to the ma-
terial to be worked.
For cutting expe-
cially 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 circular sparking, ro-
tating with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
the tool 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.

Maintenance and Service

Maintenance and Cleaning

Before any work on the power tool itself,
pull the mains plug.
For safe and proper working, always keep
the power tool and the ventilation slots
clean.
In extreme working conditions, conductive
dust can accumulate in the interior of the
power tool when working with metal. The
protective insulation of the power tool can
be degraded. The use of a stationary extrac-
tion system is recommended in such cases
as well as frequently blowing out the ventila-
tion slots and installing a ground fault circuit
interrupter (GFCI).
Please store and handle the accessory(-ies) care-
fully.
If the power tool should fail despite the care tak-
en in manufacturing and testing procedures, re-
pair should be carried out by an after-sales ser-
vice center for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit article number
given on the type plate of the power tool.
