DUST FILTER CLEANING AND INTEGRITY
CHECK
NOTE
Besides the standard paper fi lter, polyester fi lters are
also available. The following procedure is applicable
to each type of fi lter.
Drive the machine on a level ground and engage the
parking brake with the pedal (3) and the lever (4).
Turn the ignition key (72) to "0".
Disengage the hook (18) by pulling its lower end.
Remove the hopper (17) by using the handle (19) and by
disengaging it from the inner guides.
Unscrew the knobs (33) and remove the fi lter compartment
cover (32).
Loosen the knobs (A, Fig. 10).
Disconnect the connector (B, Fig. 10) from the fi lter shaker
motor (C).
Remove the dust fi lter fastening frame (D, Fig. 10).
Remove the dust fi lter (E, Fig. 10).
In an outdoor area, clean the fi lter by shaking it on a level
and clean surface, tapping the side (A, Fig. 12) opposite to
the wire gauze (B).
Complete the cleaning procedure by using compressed air
(C, Fig. 12) at maximum 6 Bars, blowing only from the side
of the wire gauze (B), at a minimum distance of 30 cm.
Moreover, according to the fi lter type, observe the following
cautions:
Paper fi lter (standard): Do not use water or detergents
to clean it, otherwise it can be damaged.
Polyester fi lter (optional): For a better cleaning, it is
allowed to wash the fi lter with water and non-lathering
detergents. This provides better quality cleaning but
reduces the life of the fi lter, which will have to be
replaced more frequently. The use of inadequate
detergents can damage the fi lter.
Check the fi lter body for tears. If necessary, replace the
fi lter.
Clean the rubber gasket (A, Fig. 11) of the cover (32) and
check it for integrity and effi ciency; if necessary replace it.
Assemble the components in the reverse order of
disassembly, and note the following:
Install the fi lter (E, Fig. 10) with the wire gauze (B, Fig.
12) facing upwards.
