The machine must be operated
only with dust extraction. The
vacuum cleaner must be ap-
proved for the extraction of ma-
sonry dust.
In case of a malfunction of the
dust extraction system, stop
working, switch the machine off
and correct the malfunction of
the dust extraction system.
The machine can be plugged directly into the re-
ceptacle of a Bosch general-purpose vac with re-
mote starting control. The vac starts automati-
cally when the machine is switched on.
The vacuum cleaner must be suitable for the ma-
terial to be worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
Bosch offers suitable vacuum cleaners for all ma-
terials to be worked.
For dust extraction using an external vacuum
cleaner, a suction adapter must be used in this
case (see accessories). Insert the suction
adapter and suction hose fixture firmly.
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.
☞
The cutting unit must have engaged in
the uppermost position before the ma-
chine is switched on, so that the dia-
mond cutting discs do not touch the
workpiece.
Switching on and off
Switching on: Slide the On/Off switch 8
forward and press down to the
front until it latches.
Switching off: Press down the On/Off switch 8
to the rear - the switch springs to
the off position.
☞
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 cutting discs that are dam-
aged, out-of-balance, or vibrate.
Starting Current Limiting
As a result of soft starting, a 13-A fuse is ade-
quate.
Constant Electronics
The constant speed electronics hold the speed at
no-load and when under load nearly constant and
ensure uniform working performance.
Overload Protection
When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately and
allow to cool for approx. 30 seconds at the high-
est no-load speed.
Restarting Protection (GNF 35 CA)
Prevents uncontrolled restarting of the machine
after an interruption in the mains supply.
The mains supply remains interrupted and the
service indicator 9 lights up.
Restarting operation: Switch the On/Off
switch 8 to the Off position and start the machine
again.
