sealed plastic bag;
■ close the bag hermetically;
■ dispose of the filter in accordance with the laws in
force.
WARNING!
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.
WARNING!
Take care not to raise dust when this operation is
carried out. Wear a P3 mask and other protective
clothing plus protective gloves (DPI) suited to the
hazardous nature of the dust collected, refer to the
