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.
For cutting especially 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.
Noticeably 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 circumstanc-
es. Before beginning work, consult the responsible structural
engineer, architect or the construction supervisor.

Maintenance and Service

Maintenance and Cleaning

 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 portable residual current device (PRCD).
When working metals, conductive dust can settle in the in-
terior of the power tool. The total insulation of the power
tool can be impaired.
Please store and handle the accessory(-ies) carefully.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
