Never allow children to use the machine.
When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
Always direct the cable to the rear away from
the machine.
Apply the machine to the workpiece only when
switched on.
Always switch off the machine and allow to
come to a stop before placing it down.
Do not clamp the machine in a vice.
Do not drill, fasten or cut into blind areas
where electric, gas or water lines may exist.
Use appropriate detectors to determine if
these lines are hidden in the work area or
call the local utility company for assis-
tance.
Contacting electric lines may cause fire or
electric shock. Striking a gas line will probably
result in explosion. Breaking into a water pipe
will cause property damage or may cause an
electric shock.
Observe the manufacturer's instructions for
mounting and operating the diamond cutting
discs.
Only use diamond cutting discs with a maxi-
mum permissible speed that is at least as high
as the no-load speed of the machine.
Check the diamond cutting discs before use.
The diamond cutting discs must be mounted in
exact alignment and be able to rotate freely.
Carry out a test run for at least 30 seconds
without any load. Do not use any diamond cut-
ting discs that are damaged, out-of-balance, or
vibrate.
Observe the dimensions of the diamond cut-
ting discs. The hole diameter must fit the
mounting flange 13. Do not use any reduction
parts or adapters.
Protect diamond cutting discs against impact,
shock and grease.
Do not work with materials containing asbes-
tos.
Keep hands away from the rotating diamond
cutting disc.
Blocking the cutting disc leads to jerking reac-
tion forces on the machine. In this case switch
off the machine immediately.

Caution! Diamond cutting discs do not stop
running immediately when the machine is
turned off. Do not exert 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 is only able to ensure perfect function-
ing of the machine if the original accessories
intended for it are used.

Intended Use

With a firm support of the cutting guide, the ma-
chine is intended for wet or dry horizontal cuts or
slots in mainly mineral materials, such as marble.
The machine is not suitable for cuts in walls or
ceilings.

Changing the Tool

A
Before any work on the machine itself, pull
the mains plug.
Wear protective gloves.
Inserting
Place the mounting flange 13 onto the motor
spindle 12. Then place the diamond cutting
disc 15 onto the motor spindle 12 and tighten us-
ing the clamping nut 16. The mounting flange 13
must thereby be held tightly using an open-ended
spanner 14.
Observe when mounting: The direction of the
respective arrows on the protective guard 6 and
diamond cutting disc 15 must agree.
Removing
Hold the mounting flange 13 tightly using the
open-ended spanner 14 and loosen the clamping
nut 16 using a two-pin spanner 17.
A Warning: Left-hand thread!
Remove clamping nut 16 and mounting flange 13
and clean.
