Maintenance, cleaning and decontamination
CAUTION!
Disconnect the machine from its power source before
cleaning, servicing, replacing parts or converting it to
obtain another version/variant.
■
Carry out only the maintenance operations
described in this manual.
■ Use only original spare parts.
■ Do not modify the machine in any way.
Failure to comply with these instructions could
jeopardize your safety. Moreover, such action would
immediately void the EC declaration of conformity/
incorporation issued with the machine.
CAUTION!
For maintenance procedures not described in this
manual, please contact the manufacturer's technical
support or sales network.
CAUTION!
To guarantee the safety level of the machine, only
original spare parts supplied by the manufacturer
should be used.
CAUTION!
The precautions described below must be taken during
all maintenance operations, including cleaning and
replacing the primary and absolute filters.
■ To allow the user to carry out the maintenance operations,
the machine must be disassembled, cleaned and
overhauled as far as is reasonably possible, without
causing hazards for the maintenance staff or other
people. The suitable precautions include decontamination
before disassembling the machine, adequate filtered
ventilation of the exhaust air from the room in which it
is disassembled, cleaning of the maintenance area, and
suitable personal protection.
■ The external parts of the machine must be decontaminated
by cleaning and vacuuming methods, dedusted or treated
with sealant before being taken out of a hazardous zone.
■ All parts of the machine must be considered as
contaminated when they are removed from the hazardous
zone and appropriate actions must be taken to prevent
dust from dispersing.
■ When maintenance or repair procedure are carried out,
all the contaminated elements that cannot be properly
cleaned, must be eliminated. These elements must be
disposed of in sealed bags in accordance with applicable
regulations and local laws on the disposal of such material.
This procedure must also be followed for filter disposal
(primary and absolute filters).

■ Compartments that are not dust-tight must be opened
with suitable tools (screwdrivers, wrenches, etc.) and
thoroughly cleaned.
■ A check must be carried out by the manufacturer or the
personnel of the same at least once a year. For example:
Check the air filters to find out whether the air-tightness of
the machine has been impaired in any way and make sure
that the electric control panel operates correctly.
Container and dust bag cleaning
Emptying the container
Before proceeding with these operations, turn off the
machine and remove the plug from the power socket.
Check the machine filtration class.
■ Remove vacuum hose (2) from the cap (1).
■ Release the cap (1) by using the knobs (3).
■ After removing the cap (1), remove the primary filter.
■ Open the container locking levers (4).
■ Empty the container (5).
■ Install the primary filter, install the cap (1) and connect the
hose (2).
After the cleaning session, leave the machine running for at
least 60 seconds before turning it off.
Avoid switching on/off too frequently.
Primary and absolute filter replacement
When the machine is used to vacuum hazardous
substances, the filters become contaminated, therefore:
■ Work with care and avoid spilling the vacuumed
dust and/or material;
■ place the disassembled and/or replaced filter in a
sealed plastic bag;
■ close the bag hermetically;
■ dispose of the filter in accordance with the laws
in force.
Filter replacement is a serious matter. The filter must be
replaced with one of identical characteristics, filtering
surface and category.
Otherwise the machine will not operate correctly.
Before proceeding with these operations, turn off the
machine and remove the plug from the power socket.
