Vacuum cleaner operation

Figure 9
1 Red zone
2 Vacuum gauge
3 Green zone
Check the flow rate:
■ When the vacuum cleaner is operating, the pointer of the
vacuum gauge (2) must remain in the green zone (OK)
(3) to ensure that the speed of the intake air does not
drop below the safety value of 20 m/sec;
■ If the pointer is in the red zone (STOP) (1) it means that
the speed of the air in the vacuum hose is less than
20 m/s and that the vacuum cleaner is not operating in
safety conditions.
In such conditions, the horn (of M and H versions) emits
a pulsing sound. The filters must be cleaned or replaced.
■ After cleaning or replacing the filters, the vacuum gauge
pointer must return to the green zone and the sound (M
and H versions) must stop.
■ When the vacuum hose is closed, the pointer of the
vacuum gauge must switch from the green zone (OK)
(3) to the red zone (STOP) (1) and the horn on M and H
versions must emit a pulsing sound.
WARNING!
If the vacuum cleaner belongs to the M or H class,
use only hoses with diameters that comply with the
indications in the Technical data table,
in order to prevent the air speed from dropping below
20 m/sec.
WARNING!
When the vacuum cleaner is operating, always check
that the vacuum gauge pointer remains in the green
zone (OK).
Consult the "Troubleshooting" chapter if faults occur.

Shaking the primary filter

Depending on the quantity of dust cleaned up, shake the
main filter by means of the lever (1, Fig. 10) when the vacuum
gauge pointer (2, Fig. 9) switches from the green zone (OK)
to the red zone (STOP) and/or the horn (of M and H versions)
emits a pulsing sound.
WARNING!
Stop the vacuum cleaner before shaking the filter.
Do not shake the filter while the vacuum cleaner is on,
as this could damage the filter itself.
Wait before restarting the vacuum cleaner, to allow the dust to
settle.
Replace the filter element if the pointer still remains in the red
zone (STOP) even after the filter has been shaken (consult
the "Primary filter replacement" paragraph).

Emergency stopping

Turn the main switch to "0" position.

Emptying the dust container

WARNING!
■ Turn off the vacuum cleaner and remove the plug
from the power socket before proceeding with
this operation.
■ Check the class of the vacuum cleaner.
Before emptying the container it is advisable to clean the filter
(see "Shaking the main filter" paragraph).
