Carefully read 0.5.1 (PRECAUTIONS AND GENERAL
INFORMATIONS).
For the maintenance intervals, see 2.1.1 (REGULAR
SERVICE INTERVALS CHART) under:
– Air cleaner.
a
CAUTION
The partial cleaning of the filter does not exclude or
postpone the replacement of the filter itself.
Do not start the engine if the air cleaner has been re-
moved.
Do not clean the filtering element with petrol or sol-
vents, since they may cause a fire in the fuel supply
system, with serious danger for the persons in the vi-
cinity and for the vehicle.
DO NOT DISPOSE OF POLLUTING SUBSTANCES OR
COMPONENTS IN THE ENVIRONMENT.
◆
On each maintenance operation, remove the small plug
(1), drain the contents into a container and then deliver
it to a salvage center.
REMOVAL
◆
Remove the saddle, see p 7.1.7 (REMOVING THE
SADDLE).
◆
Rotate the air conveyor (1) clockwise, then lift and re-
move it.
◆
Check the conditions of the gasket (2) and change it if it
is damaged.
◆
Extract the air cleaner (3).
a
CAUTION
Plug the opening with a clean cloth, in order to pre-
vent any foreign matter to get ito the suction ducts.
Make sure that the filtering element is positioned cor-
rectly, in such a way as to prevent non-filtered air
from entering.
Remember that the untimely wear of the piston seg-
ments and the cylinder may be caused by a faulty or
uncorrectly positioned filtering element.
PARTIAL CLEANING
a
CAUTION
Do not press or strike the metal net of the air cleaner
(3).
Do not use screwdrivers or alike.
◆
Seize the air cleaner (3) vertically and strike it more
than once on a clean surface.
◆
If necessary, clean the air cleaner (3) with a com-
pressed air jet (directing it from the inside towards the
outside of the filter).
a
CAUTION
When cleaning the filtering element, make sure that
there are no tears.
Otherwise, change the filtering element.
◆
Clean the outer part of the air cleaner (3) with a clean
cloth.
CHANGING
a
CAUTION
Do not use filters that have already been used.
◆
Replace the air cleaner (3) with a new one of the same
type.
◆
Put back the saddle, see 7.1.7 (REMOVING THE SAD-
DLE).
◆
Remove the plug (4). Empty its content into a container
and deliver it to a salvage centre.
a
CAUTION
Do not use filters that have already been used.
Make sure that the filtering element is positioned cor-
rectly, in such a way as to prevent non-filtered air
from entering.
Remember that the untimely wear of the piston seg-
ments and the cylinder may be caused by a faulty or
uncorrectly positioned filtering element.
If the vehicle is used in dusty areas, clean the filtering
element more frequently.
Using the vehicle without the filtering element, or
with the element damaged, considerably increases
wear and tear on the engine.
Make sure the filtering element is always in perfect
condition. The life of the engine depends, for the
most part, on this component.
