Main and absolute filter disassembly and
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.

as described in the "Maintenance, cleaning and
decontamination" paragraph.
Take care not to raise dust during this operation. Wear
a P3 mask and other protective clothing plus protective
