Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
vacuum cleaner. Equipment marked with
230 V can also be operated with 220 V.
Please inform yourself about the valid regu-
lations/laws for your country concerning
the handling of materials that are hazard-
ous to one's health.

Wear a dust respirator.
Note: In IS operating mode, it is only allowed to
use the 35 mm hose and nozzle program.
To start the operation of the vac, set the mode
selector switch 6 to on.
To switch off the vac, set the mode selector

Bosch Power Tools
The vacuum cleaner is equipped with an airflow
monitoring system (Airflow). In the IS operating
mode, the airflow is continuously set to a value
of 20 m/s, independent of the positoin of the
Airflow regulator 5.
If this value is fallen below, e. g. caused through
debris accumulated in the vacuum hose, a full
dust bag or a clogged folded filter, warning light
4 flashes. In this case, shut the vacuum cleaner
off and check it as described under "Malfunc-
tions".
Extracting Dusts Resulting from Running
Power Tools (ENT Operating Mode with
Remote Automatic Switching) (see figure B)
Wear a dust respirator.
An adequate ventilation rate (L) must be
provided for when the outgoing air is circu-
lated. Observe the respective national regu-
lations. Measured with a Ø 35 mm and 5 m
long vacuum hose, the max. airflow is
3
140 m /h and the max. vacuum is 225 hPa.
A socket outlet with earthing contact 7 is inte-
grated in the vacuum cleaner, which allows for
connection of an external power tool. The vacu-
um cleaner is automatically put into operation
via the power tool. Observe the maximal allowa-
ble load of the connected power tool.
For connecting power tools, various hose sys-
tems are available as accessories.
Set the Airflow regulator 5 to the hose diameter
being used (19 mm or 35 mm).
To ensure sufficient dust transport at the vacu-
um location, the minimum airflow for the power
tool connected may not be fallen below.

Set the mode selector switch 6 to the operation
with remote automatic switching symbol.
In this operating mode, the airflow is electroni-
cally monitored according to the setting of the
Airflow regulator 5. Sufficient dust transport is
ensured when the setting is correctly selected.
