Never set down a coasting machine on the
chaser rollers 3, but always aside, so that
the diamond cutting discs can rotate freely
and do not face toward your body.
Diamond cutting discs become very hot dur-
ing operation; do not touch them until they
have cooled down.
Remove the remaining fin of the material with
the break-out tool 21.
Curved cuts are not possible, as the diamond
cutting discs could jam in the material.
When cutting through plate materials, ensure
that the materials are firmly backed on a surface
or supported.
When breaking through walls, e. g. with a rotary
hammer, most of the chipping-off of the surface
material can be avoided by first cutting in a slot
with maximum cutting depth.
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.
The permitted slot depth and width depends on
21
the slot length, wall thickness and the building
material used.

Maintenance and Cleaning

After finishing work, dismount the clamping fix-
tures and clean all clamping parts as well as the
protective cover.
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.
