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. Make sure that the
machine cannot move independently; if equipped, press
the pedal brake (26).
Turn the ignition key (61) to "0".
Disengage the debris container hook (18).
Remove the debris container (17) with the handle (19).
Turn the handle (A, Fig. 11) upwards (90° approximately)
and let the fi lter frame (B) turn outward.
Remove the dust fi lter (C, Fig. 11).
In an outdoor area, clean the dust 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 Bar, blowing only from the side
protected by the wire gauze (B).
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, clean the fi lter compartment rubber gasket
(D, Fig. 11) along its perimeter and check it for integrity. If
necessary, replace it.
Assemble the components in the reverse order of
disassembly, and note the following:
Install the fi lter (C, Fig. 11) with the wire gauze (B, Fig.
12) turned towards the machine front side.
