MAINTENANCE
6 Fit new filter bag assembly into supporting frame, feeding individual filter
bags between locating bars, and fold collar over peripheral sealing flange.
7 Prior to fitting wire mesh inserts, any material edgings that need replacing
should be fitted around the three edges of the insert that do not have the
insert frame joint. The inserts should then be fitted, edging first, into the filter
bags.

the filter bags make contact with the shaker bar.
