Check for correct mains voltage: The voltage
of the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Functional test for residual current device 5
For safety reasons, before commencing work,
check that the residual current device 5 is func-
tioning properly:
– Press the “RESET” button on the residual cur-
rent device.
The red control lamp indicates that the residual
current device is ready for use.
– Press the “TEST” button.
The control lamp must go out.
– Press the “RESET” button on the residual cur-
rent device.
Switching on:
Actuate the switch lock 2.
Press the On/Off switch 3 and hold pressed.
Note: The On/Off switch 3 cannot be locked on.
Switching off:
Release the On/Off switch 3.
Wear protective goggles, ear
protection and a dust protection
mask.
Wear protective gloves and
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
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.
■
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.
