Never set down the rotating machine on the
chaser rollers 10, moreover lay it on the
side so that the cutting discs can run freely
and do not point toward the body.
Caution! The diamond cutting discs and
the extraction elbow get very hot while
working; do not touch them until they have
cooled down.

Remove the remaining fin of the material with the
break-out tool 18, included in the delivery.
Curved cuts are not possible, as the diamond cut-
ting discs could jam in the material.
When cutting through plate materials, ensure that
the materials are firmly backed on a surface or
supported.
To guide the machine better while cutting
horizontal/diagonal slots in walls, a wooden lath
can be used as an auxiliary guide.
When breaking through walls, e. g. with a rotary
hammer, avoid most of the chipping off of the sur-
face material by first cutting in a slot with maxi-
mum cutting depth.
For cutting especially hard materials, e. g.,
concrete with high gravel content, the dia-
mond cutting disc can overheat and be-
come damaged as a result. This is indi-
cated clearly by a ring of sparks that rotates
with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by letting it
run freely at a no-load speed for a short time.
A noticeable drop in work performance and a ro-
tating spark ring indicate that the diamond cutting
disc has become dull. It can be resharpened with
brief cuts in an abrasive material (e. g., chalky
sand stone).

Maintenance and Cleaning

After finishing work, disassemble the diamond
cutting discs and clean the clamping parts and
the protective cover.
Should the machine fail in spite of careful manu-
facturing and testing, its repair should be carried
out by a Bosch power tools authorized service
agent.
For all correspondence and spare parts orders,
always include the 10-digit part number of the
machine!

Noise/Vibration Information

Measured values determined according to
EN 50 144 (lime-sand brick).
The A-weighted noise levels of the tool are typi-
cally: Sound pressure level: 97 dB (A); sound
power level: 110 dB (A).
Wear ear protection!
The weighted acceleration is typically 6 m/s

Environmental Protection

Recycle raw materials instead of disposing
them as waste
The machine, its accessories and packaging ma-
terials should be sorted for environmentally-
friendly recycling.
These instructions are printed on chlorine-free re-
cycled paper.
The plastic components are labeled for catego-
rized recycling.
English - 5
Before any work on the machine itself, pull
the power plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
