) (figure 4) to “0” position.
Emptying the dust container
WARNING!
Before proceeding with these operations, turn off the
vacuum cleaner and remove the plug from the power
socket.

Normal version
■ Release the dust container ( 1 ) using the lever ( 2 ), then
remove and empty it.
■ Make sure that the gasket is in perfect condition and
correctly positioned.
■ Place the container back in position and use the lever to
secure it again.
Operation of the filtering cartridges
Figure 9
1 Electropneumatic device
2 Filtering cartridges
3 Timer
The filtering cartridges ( 2 ) serve the purpose of filtering the
intake air. The vacuum cleaner is equipped with a fully automatic
electropneumatic device ( 1 ) to alternately clean the filtering
cartridges ( 2 ), which guarantees continuous service;
powered with a 24V rating, is complete with cyclic timer ( 3 ) to
regulate the following times:
T3 = time between one cleaning cycle and the next, set on 1
minute;
T2 = time between one cleaning operation of the cartridge ( 2 )
and the next, set on 30 seconds;
T1 = opening time of the solenoid valve for backwashed air
exhaust into the cartridge, set at 2 tenths of a second.
The shorter the time, the more energetic the cleaning
action will be.
Check the arrows on the knobs of the timer ( 3 ) for the
exact regulation.
The three solenoid valves of the electropneumatic device
control the cleaning of the relative filter cartridges.

Lock the castor brakes before starting the vacuum cleaner ( 1 ).
Starting/stopping the vacuum cleaner
■ Turn the switch ( 3 ) (figure 4) to “I” position to electrically
power the vacuum cleaner. The voltage presence
indicator ( 6 ) (figure 4) comes on.
■ Push the start button ( 4 ) (figure 4) to start the vacuum
cleaner.
■ Push the stop button ( 5 ) (figure 4) to stop the vacuum
cleaner.
■ Turn the switch ( 3 ) (figure 4) in “0” position to electrically
cut off the power of the vacuum cleaner.
WARNING!
The start/stop button (8 and 10) (figure 4) of the
compressor should always be in “I” position during
the operation.
WARNING!
Check the pressure of the air used to clean the filters
which is produced by the compressor.
It must never be superior than 5 bars, if necessary,
adjust it to the correct level using the related pressure
governors (9 e 11) (figure 4).
WARNING!
The activation of the indicator (7) (figure 4) signals the
operation of the vacuum unit thermal protection due
to the excessive electrical power draw of the unit.
