Operation

Figure 8
Vacuum gauge (2): green zone (3), red zone (1)
When using the machine, check the flow control:
■ when the machine 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 machine 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).
CAUTION!
When the machine is operating, always check that the
vacuum gauge pointer remains in the green zone (3).
Consult the "Troubleshooting" chapter if faults occur.
CAUTION!
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).
CAUTION!
All machines can be used only with hoses whose
diameters comply with the specifications in the
"Technical Data" table.
CAUTION!
Consult the "Troubleshooting" chapter if faults occur.
