Operating the vacuum

Figure 7

Red Zone

Green Zone
Check the flow rate:
When the vacuum cleaner is operating, the pointer of the
vacuum gauge (A) must remain in the green zone (OK)
to ensure that the speed of the intaken air does not drop
below the safety value of 20 m/s.
If the pointer is in the red zone (STOP), it means that
the speed of the air in the hose is below 20 m/s and that
the vacuum cleaner is not working in safety conditions.
Clean or replace the filters.
When the hose is blocked, the pointer of the vacuum
gauge must switch from the green zone (OK) to the red
zone (STOP).
WARNING!
If the vacuum cleaner is Class M or H, only use hoses
with diameters that comply with the indications in the
"Technical Specifications" Table in order to prevent
the air speed from dropping below 20 m/s
WARNING!
When the vacuum cleaner is operating, always check
to make sure that the vacuum gauge pointer remains
in the green zone (OK).
Consult the "Troubleshooting" chapter if faults occur.

Shaking the main filter

Figures 7-8
Depending on the quantity of dust cleaned up, shake the
main filter by means of the knob (J) when the vacuum gauge
pointer (A) switches from the green zone (OK) to the red zone
(STOP).
WARNING!
Stop the machine before shaking the filter.
Do not shake the filter whilst the machine 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 "Main filter replacement" section).
