Operation
Figure 7
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
).
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!
