Vacuum cleaner operation
Turn the main switch to “0” position.
Vacuum gauge (2): green zone (3), red zone (1)
Check the flow rate:
■■ when the vacuum cleaner is operating, the pointer of the vacuum gauge must remain in the green zone (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 (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. The filters must be shaken or replaced. ■■ during normal operation conditions, close the vacuum hose, the pointer of the vacuum gauge must switch from the green zone (3) to the red zone (1).
■■ Before proceeding with these operations, turn off the vacuum cleaner and remove the plug from the power socket. ■■ Check the class of the vacuum cleaner. Before emptying the container it is advisable to shake the filter (see “Shaking the main filter” paragraph). ■■
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. This is done in order to prevent the air speed from dropping below 20 m/sec.
Normal version not suitable for vacuuming hazardous dust
▪▪ Release the dust container (1, Fig. 11), then remove and empty it. ▪▪ Make sure the seal is in perfect condition and correctly positioned. ▪▪ Place the container back in position and secure it again.
A plastic bag can be used to collect dust (see Fig. 11).
In this case, the vacuum cleaner must be equipped with optional accessories [depressor (3) and grid (2), Fig. 11].
When the vacuum cleaner is operating, always check that the vacuum gauge pointer remains in the green zone (3).
