Nm.
■ Loosen the clamp (2).
■ Remove the vacuum hose (1).
■ Operate the levers (4).
■ Remove the cover (3) and the filter ring (5).
■ Disconnect the power supply cable (7) and the compressed
air supply from the air intake coupling (8).
■ Remove the cartridge assembly (6).
■ Disconnect the connectors (10) and the union (9).
■ Disassemble the air tank by operating on the screws (11).
■ Unlock the fastening devices (12) and lift the cartridges
(13), paying attention to the dust on them and place them
in a plastic bag.
■ Get four cartridges with the same characteristics. These
will be supplied with the gasket which must be positioned
in the relevant housing on the lower side of the cartridge
fastening flange.
Gasket replacement is of the utmost importance since
it must ensure a perfectly tight seal between the filter
chamber and cartridge, thus preventing dust from
leaking out.
■ Fit the tank back in place by repeating the above
operations in reverse order.
Primary filter replacement, for machines equipped
with electric filter shaker cleaning system
■ Remove the hose from the upper inlet.
■ Release the closing band and remove the cover.
■ Sling the cover and lift it carefully, because the star-shaped
filter and the shaking cage are connected to the cover.
Do not rest the cover-star-shaped filter assembly
vertically on the ground, but use suitable supports or
rest it sideways, as the weight of the cover can damage
the filter and the shaking cage.
■ Lift the filter (6), unscrew the clamp (7) and remove the
ring (8).
■ Cut the clamps (10) and detach the cage from the filter.
■ Fit the filter catch and retention ring of the old filter on to
the new one.
■ Insert the cage (9) and fix it to the filter by means of the
clamps (10) on the bottom of the filter itself.
■ After removing the plastic cover, check that:
- The lever (11) fastened to the drive shaft (12) of the
cage (10) must be halfway along its travel in the neutral
central position.
- The connecting rod (13) fastened to the reduction
unit (14) must point downwards. Only in this way, when
operating the reduction unit (14), the cage (10) will cover
an equal travel to the right and left when, without tightening
the filter (8). The filter could be torn and the motor of the
reduction unit burnt out if this is not done.
■ Fit the filter into the filtering chamber, then mount the
cover and lock it in place with the two fastening latches.
