– fit the filter catch and retention ring of the old filter on the
new one;
– insert cage “4” and fix it to the filter by means of plastic
strips “2” at the bottom of the filter itself;
– mount the filter rod in the filter shaker system and
tighten the bolt;
– fix the top cover of the filter assembly;
– fit the filter assembly back into the machine;
– fit the suction pipe “1” back into position;

Filter replacement is an important operation.
The filter must be replaced with one of
