Routinely clean the dust-removal filter 7 (Fig. 3) according to the following indications:
Rotate the filter fastener plate and pull out the dust-removal filter from its seat;
Visually check the degree of dirtiness;
In normal situations it is sufficient to suction in the direction opposite normal flow;
In other cases it is necessary to wash the filter with soap and water and rinse with a slight waterjet
(max. 40°C) in the direction opposite normal flow; in this case, wait for the filter to be dry before
putting it back in the machine;
If the filter is excessively dirty, replace it with an original spare filter.

Routinely check for signs of clogging on the front grille for air outflow so performance is not hindered; if
necessary, vacuum the dirt and remove it with a brush.
