Do not reduce the speed of running down cut-
ting discs by applying sideward pressure.

The machine must 
always work in an 
up-grinding mo-
tion. Otherwise, 
the danger exists 
of it being pushed 

uncontrolled

 out 

of the cut.
When cutting pro-
files and square 
bar, it is best to 
start at the small

est cross section.

Cutting Stone (see figure A)

f

For cutting stone, always work with the cut-
ting guide with dust extraction protection 
guard 17.

f

The machine may be used only for dry cut-
ting/grinding.

For cutting stone, it is best to use a diamond 
cutting disc. As a safety measure against jam-
ming, the cutting guide with dust extraction pro-
tection guard 

17

 must be used.

Operate the machine only with dust extraction 
and additionally wear a dust protection mask.
The vacuum cleaner must be approved for the 
extraction of masonry dust. Bosch provides suit-
able vacuum cleaners.

Switch on the ma-
chine and place 
the front part of 
the cutting guide 
on the workpiece. 
Slide the machine 
with moderate 
feed, adapted to 
the material to be 
worked.

For cutting expecially hard material, e. g., con-
crete 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 al-
low the diamond cutting disc to cool by running 
the machine 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.

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 
circumstances. Before beginning work, consult 
the responsible structural engineer, architect or 
the construction supervisor.

Maintenance and Service

Maintenance and Cleaning

f

Before any work on the machine itself, pull 
the mains plug.

f

For safe and proper working, always keep 
the machine and ventilation slots clean.

f

In extreme conditions, always use dust ex-
traction as far as possible. Blow out ventila-
tion slots frequently and install a residual 
current device (RCD). 

When working metals, 

conductive dust can settle in the interior of 
the power tool. The total insulation of the 
power tool can be impaired.

Please store and handle the accessory(-ies) 
carefully.
If the machine should fail despite the care taken 
in manufacturing 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 include the 10-digit article 
number given on the type plate of the machine.
