Inspections prior to starting

igure 5
F
1. 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.
Do not use the device if the filter is faulty.
Starting
Figure 6
1. Castor brakes
2. 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.
