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 20m / 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 20m / 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!
