Operation
Vacuum gauge (2): green zone (3), red zone (1)
When using the vacuum cleaner:, check the flow control:
■ 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 optimal
conditions. Shake or replace the filter.
■ 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).
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.
The air speed in the suction tube must not be less
than 20 m/s.
Condition indicated by the vacuum gauge pointer in
the green zone (3).
All vacuum cleaners can be used only with hoses
whose diameters comply with the specifications in the
"Technical Data" table.
Consult the "Troubleshooting" chapter if faults occur.
