Inspections prior to starting

Prior to starting, check that:
– The filters are installed;
– all latches are tightly locked;
– The hose and tools have been correctly fitted into inlet "F"
(Fig. 5);
– The bag or safety container are installed, if applicable.
– Do not use the vacuum cleaner if the filter is faulty.

Starting up

– Lock the castor brakes "E" (Fig. 6) before starting the
vacuum cleaner.
– Move switch "B" (Fig. 6) to the On position ("I").
– If the vacuum cleaner has been working and then stops and
the indicator light "C" (Fig. 4) comes on, or if the vacuum
cleaner motor turns in the wrong direction, turn it off and turn
the inverter "F".

Operating the vacuum

1. RED ZONE
2. GREEN ZONE
Check the flow rate:
– When the vacuum cleaner is operating, the pointer of the
vacuum gauge "A" (Fig. 7) must remain in the green zone
(OK) to ensure that the speed of the intake 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 safely. 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!
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 problems occur.

Cleaning the main filter

Depending on the quantity of dust cleaned up, shake the main
filter by means of the knob "J" (Fig. 8) when the vacuum gauge
pointer "A" (Fig. 7) switches from the green zone (OK) to the red
zone (STOP).
WARNING!
Stop the machine before shaking the filter.
Do not shake the filter while the machine is on as this could
damage the filter.
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).
