dust and/or material;

sealed plastic bag;
■ 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 vacuum cleaner will not operate
correctly.

Take care not to raise dust when this operation
is carried out. Wear an N100 (P3) mask and other
protective clothing plus protective gloves (PPE / DPI)
suited to the hazardous nature of the dust collected;
