of the power source must agree with the voltage
specified on the nameplate of the machine.

Operating Instructions
Wear protective goggles, ear
protection and a dust protection
mask.
Wear
sturdy shoes.
Clamp the workpiece if it does not remain
stationary due to its own weight.
Do not load the machine so heavily that it
comes to a standstill.
Caution! Diamond cutting discs become
very hot during operation; do not touch
them before they have cooled down.
When cutting, do not press, tilt or oscillate. Work
with moderate advancing that is adapted to the
material being worked.
Do not brake coasting cutting disks with side
pressure.
The 0° cut marking 10 shows the position of the
diamond cutting wheel for a cut at right angles.
For optimum results, we recommend using the
diamond cutting wheels that have been specially
adapted for the diamond cutter. These have a
higher service life and produce better working re-
sults.
It is possible to use the high-grade diamond cut-
ting wheels of Ø 125 mm from the Bosch angle-
grinder auxiliaries program.

Cutting direction

E
Important is the direction in which cutting is per-
formed.
The machine must always run in counterrota-
tion; therefore push the machine forwards! Oth-
erwise there will be a danger of it being pressed
out of the cut in an uncontrolled fashion.

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an authorized after-sales
service centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order number
given on the nameplate of the machine.
