Cutting Metal
For cutting metal, always work with the pro-
tection guard for cutting 15.
When cutting, work with moderate feed, adapt-
ed to the material being cut. Do not exert pres-
sure onto the cutting disc, tilt or oscillate the
machine.
Do not reduce the speed of running down cut-
ting discs by applying sideward pressure.
Cutting Stone
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 25.
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 25 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.

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.
Recommendations for Optimal Handling
of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature
range between 0 °C and 45 °C. As an example,
do not leave the battery in the car in summer.
Occasionally clean the venting slots of the bat-
tery using a soft, clean and dry brush.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
