Before starting, check that:
■ The filters are installed.
■ The closing band is properly tightened.
■ The vacuum hose and tools have been correctly fitted into
the vacuum inlet (1).
■ In case of liquid application, the liquid mechanical stop is
properly installed inside the liquid container:
■ The bag or safety container is installed, if applicable.
CAUTION!
Do not use the device if the filters are faulty.

CAUTION!
The motors and internal components of the vacuum
cleaner will still be electrically powered.

Operation

Figure 7
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!
The air speed in the vacuum hose must not be less than
20 m/s.
This state is shown by the green indicator of the primary
filter.
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.
At the end of a cleaning session
■ Turn off the machine and remove the plug from the socket.
■ Wind up the connection cable.
■ Empty the container and clean the machine as described
in the "Maintenance, cleaning and decontamination"
paragraph.
■ Wash the container with clean water if aggressive
substances have been vacuumed.
■ Store the machine in a dry place, out of reach of
unauthorised people.
■ Lock the castor brakes.
■ During transport and when not using the machine, close
the vacuum inlet with the relevant plug (if equipped).
