6 Controls (Fig. 3)
1. Filter clogging indicator. When the yellow light turns
on, the filter is clogged or the suction flow is
obstructed downstream of the filter. Remove the
accessories and try to check.
If the yellow light stays on, the filter must be cleaned
and, if necessary, replaced. For further information,
see paragraph 8.2.
2. Power on indicator
3. If the white light turns on, the vacuum cleaner is
operating.
Motors ON/OFF switches, green coloured (there
can be 2 or 3 switches, according to the type of
vacuum cleaner).
7 Starting and stopping (Fig. 3
and 4)
7.1 Precautions
7.2 Starting
Make sure that the vacuum cleaner has been properly
connected to the electrical mains. In particular, ensure
that the electrical mains voltage and frequency values
match the data on the vacuum cleaner plate (see
Fig.1).
Install the desired accessories to the suction inlet.
Bring the vacuum cleaner where it has to be used. Lock
the front wheels by pressing the locking levers
downwards.
Insert the power cord plug into the wall socket.
In order to start the motors (2 or 3 motors), press the
green switches, one at a time.
The lighting of the green light indicates that the motor is
running.
In order to obtain the maximum suction power, all the
motors (2 or 3) must be turned on, and they must
operate simultaneously.
The motors must always be turned ON and OFF one at
a time.
When a lower suction power is required, it is possible to
use only one motor at a time.
8 How to use the vacuum
cleaner
8.1 Correct use
Before using the vacuum cleaner, connect the hose to
the suction inlet (see paragraph 7.2).
If the suction hoses are very long, try to keep them as
straight as possible.
Do not allow them to become bent or twisted as this will
cause easy wear and clogging.
When the vacuum cleaner is turned on, the suction
power is created to collect the waste material through
the suction inlet.
The waste material passes through the hose and the
accessories until it reaches the suction inlet “4” and
then proceeds to the dust container “6” where a baffle
“5” in the filtering unit subjects it to a centrifugal action
causing the heavier solids to drop to the bottom of the
dust container “6”.
The main filter “3” retains the lighter particles in the
suction flow which proceeds to the HEPA filter, if
installed.
WARNING!
Unauthorized personnel are forbidden to
use the vacuum cleaner.
The operator must make sure that the all
protections and safety devices are
installed and efficient.
WARNING!
If the vacuum cleaner is used for
collecting fluids or wet materials, and
leaks occur, the vacuum cleaner must be
immediately turned off, cleaned and dried,
and all filters must be replaced.
