Inspections prior to starting

1. Inlet
Prior to starting, check that:
■ the filters are installed
■ all latches are tightly locked
■ the vacuum hose and tools have been correctly fitted into

WARNING!
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 does not vacuum any air, 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.

Vacuum cleaner operation

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!
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.
WARNING!
When the vacuum cleaner is operating, always check
that the vacuum gauge pointer remains in the green
zone (3).
Consult the "Troubleshooting" chapter if faults occur.
WARNING!
Class H AA - Asbestos variant:
■ This variant has a 70 mm diameter exhaust port
where the exhaust hose is connected.
Only D = 70 mm is tolerated.
Only an exhaust hose with D = 70 mm and L < 5 m
can be used.
■ Shut the inlet with an appropriate plug when
transporting the vacuum cleaner.
■ Comply with all other prescriptions for class H
vacuum cleaners.
