Removal; Cleaning The Air Filter - APRILIA AREA 51 - 1998 Manual


Do not use petrol or inflammable
solvents to wash the air cleaner,
in order to avoid fires or explo-
sions.

Carefully read p. 35 (MAINTENANCE).
Remember: 1 mile = 1.6 km
1 km = 0.625 miles
Check the conditions of the air cleaner and
clean it monthly or every 4000 km, depend-
ing on the conditions in which the vehicle is
used.
If the vehicle is used on dusty or wet roads,
the cleaning operations and any replace-
ment should be carried out more frequent-
ly.
To clean the filtering element it is neces-
sary to remove the whole filter casing from
the vehicle.

REMOVAL

Remove the left inspection cover, see
p. 46 (REMOVING THE RIGHT AND
LEFT INSPECTION COVERS).
Insert the spanner in the appropriate
hole (1), while unscrewing and removing

the screw (2) with the relevant washer.
Upon reassembly, position the
rear brake cable eyelet (3) cor-
rectly.
Unscrew and remove the screw (4) with
the relevant washer.
Loosen the screw (5) of the air manifold
clamp.
Grasp the air manifold in correspond-
ence with the clamp and pull it, thus re-
moving the whole air cleaner casing.

CLEANING THE AIR FILTER

Unscrew the three screws (6).
Remove the filter case cover (7) and ex-
tract the filtering element (8).
To clean the filtering element use clean,
non-inflammable solvents or solvents

Apply a filter oil or a thick oil (SAE 80W-
90) on the whole surface of the filtering
element, then squeeze it to eliminate the
oil in excess.

The filter must be well impreg-
nated, though not dripping.
