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 circular sparking, rotating with
the diamond cutting disc.
In this case, interrupt the cutting process and allow
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 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.
Information on Structures
Slots in structural walls are subject to the Standard
DIN 1053 Part 1, or country-specific regulations.
These regulations are to be observed under all cir-
cumstances. Before beginning work, consult the
responsible structural engineer, architect or the con-
struction supervisor.

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).
If the power tool should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service 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.
