Inspections prior to starting

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.
■ 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.

Starting and stopping

CAUTION!
Lock the castor brakes before starting the vacuum
cleaner.
Figure 5
■ Turn the manual motor starter (3) to the "I" position to start
the vacuum cleaner. Turn the manual motor starter (3) to
the "O" position to turn the vacuum cleaner off.
Machines equipped with system for vacuuming
liquids
■ When the container is full, the liquid mechanical stop turns
off the vacuuming; the vacuum unit remains on.
■ Do not let the vacuum unit running, after the liquid stop
has been activated. Turn it off with the relevant switch.

Emergency stopping

Turn the switch to "0" to turn off the machine.
CAUTION!
The motors and internal components of the machine
will still be electrically powered.

Operation

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).
The air speed in the vacuum hose must not be less than
20 m/s.
Condition indicated by the vacuum gauge pointer in the
green zone (3).
All machines can be used only with hoses whose
diameters comply with the specifications in the
"Technical Data" table.
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).
