• Do not clamp the machine in a vice.
• Never remove the protection of rubber of the switch.
They prevent the penetration of water and dust in the
switch.
• Install and adjust the water jet only with the machine
turned off.
• Be careful of hidden electrical lines or gas and water
pipes. Check the working area, e. g. with a metal detec-
tor.
• Observe the manufacturer’s instructions for mounting
and operating the diamond cutting discs.
• Only use diamond cutting discs with a maximum permis-
sible speed that is at least as high as the no-load speed
of the machine.
• Check the diamond cutting discs before use. The dia-
mond cutting discs must be mounted in a exact align-
ment and be able to rotate freely. Carry out a test run for
at least 30 seconds without any load. Do not use any di-
amond cutting discs that are damaged, out-of-balance,
or vibrate.
• Observe the dimensions of the diamond cutting discs.
The hole diameter must fit the mounting flange
10
. Do
not use any reduction parts or adapters.
• Protect diamond cutting discs against impact, shock and
grease.
• Do not work with materials containing asbestos.
• Keep hands away from the rotating diamond cutting
disc.
• Blocking the cutting discs leads to jerking reaction forc-
es on the machine. In this case switch off the ma-chine
immediately.
! Caution!
Diamond cutting discs do not stop running
immediately when the machine is turned off. Do not ex-
ert any pressure against the side of the diamond cutting
discs.
! Caution!
Diamond cutting discs become very hot
during operation; do not touch them before they have
cooled down.
•
Bosch can assure flawless functioning of the
machine only when the original accessories are
used.
Changing the tool (fig. A)
•
Before any work on the machine itself, pull the
mains plug.
• Wear protective gloves.
• Make sure the diamond wheel is correct and in perfect
working conditions.

and displace
the base plate
6
through its back side, lowering or lifting it,
until reaching the desired measure.
Raise:
for smaller cutting depths
Lower:
for greater cutting depths
Use a ruler or scale or something similar to adjust the
depth required. Tighten winged screw
18
.
Keep a uniform feeding speed all along the cut. If you want
a perfect cut, the cut-off wheel has to trespass the mate-
