Inlet
Prior to starting, check that:
■ The filter is installed;
■ All latches are tightly locked;
■ The vacuum hose and tools have been correctly fitted
into the inlet ( 1 );
■ The bag is installed.

Start switch
Lock the castor brakes ( 1 ) before starting the vacuum
cleaner.
Starting/stopping the vacuum cleaner
■ Turn the switch ( 2 ) to “I” position to start the vacuum
cleaner.
■ Turn the switch to “0” position to turn the vacuum
cleaner off.
Checking the rotation direction of the
vacuum unit motor
Check the vacuum cleaner operation by putting a hand on
the inlet.
If the vacuum cleaner expels the air from the vacuum hose,
the rotation direction is not correct; remove the plug from
the socket and turn the selector inside the plug to perform
the correct phase connection.
Operation
Figure 7
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
).
WARNING!
When the vacuum cleaner is operating, always check
that the vacuum gauge pointer remains in the green
zone (2).
Consult the “Troubleshooting” chapter if faults occur.
WARNING!
Class H AA - Asbestos variant:
■ This variant has a 100 mm diameter exhaust port
where the exhaust hose is connected.
Only an exhaust hose with D = 100 mm and L < 5
m can be used.
■ Shut the inlet with appropriate plug (see Fig. 14)
when transporting the vacuum cleaner.
■ Comply with all other prescriptions for class H
vacuum cleaners.
