8.2 Cleaning the main filter
For dust class “M” and “H”, it is necessary to close the
suction inlet with a plug during transport or filter
shacking.
The filter clogging light (warning light) “1” is installed on
the front part of the vacuum cleaner (see Fig. 3) and it
turns on when the vacuum inside the vacuum cleaner
is too high. This means that the filter is clogged and that
the filtering capacity is reduced. In this case, it will be
necessary to clean the main filter.
Turn off the vacuum cleaner by pushing the green
ON/OFF switches (2 or 3, depending on the model in
use) (Fig. 3).
Repeatedly press the filter shaker handle “2” in order to
shake off the dust from the filter.
Wait for a few minutes, to allow the dust to deposit at
the bottom of the container. Then empty the container
as described in the paragraph 8.3.
8.3 Emptying the dust container (Fig.
6)
The dust container emptying, servicing and removal
procedures must be performed only by qualified
technicians wearing appropriate protective clothing. Do
not operate the vacuum cleaner if the filtering system is
not working properly.
Check the amount of waste material inside the dust
container according to the job in hand, to prevent the
dust container from becoming excessively full.
Before emptying the dust container “1”, turn off the
vacuum cleaner by pressing the green ON/OFF
switches (2 or 3).
Moreover, it is advisable to clean the main filter with the
filter shaker handle (see the paragraph 8.2).
Wait for a few minutes, to allow the dust to deposit at
the bottom of the container “1”.
Lift the lever “4”.
The dust container “1” lowers until it rests with its
wheels on the floor.
Start the motor again and proceed as follows.
Grip the handle “2”, remove the dust container and
empty it.
To make emptying the container “1” easier, a lifting
system is available, and it can be used for lifting the
dust container with a hoist or a crane.
This toxic dust must be disposed of by means of an
appropriate system.
The code numbers of these accessories are listed in
chapter 9.
To reinstall the dust container, place it under the
filtering unit “5”.
Push down the lever “4” to lift the dust container “1” until
it engages, creating a tight fit against the filtering unit
“5”.
To make dust container emptying and cleaning easier,
it is advisable to use the special plastic bags “1”, see
Fig. 7.
Take special care when emptying dust container
containing dust belonging to class H and M, wear a P3
mask and appropriate protective clothing.
Do not throw away the plastic bag (SAFE BAG) when it
contains toxic dust or harmful material. In this case, the
plastic bag must be handed over to the authorities in
possession of necessary permission to dispose of this
kind of waste material.

If the filter clogging indicator “1” (Fig. 3) stays
on, the suction hose or an accessory is
clogged.
