2.10 AIR FILTER

Carefully read 1.3.9 (PRECAUTIONS AND GENERAL
INFORMATION).
Inspect the air filter every 4687 mi (7500 Km) or 8
months, and replace it every 9375 mi (15000 Km) or 16
months, or more frequently if the vehicle is used on dusty
or wet roads.
In this case you may wish to partially clean the air filter
after traveling on such roads.
WARNING
Partial cleaning of the air filter is no substitute for
replacing the filter, nor does it postpone the need to
do so. Do not start the engine with the air filter
removed. Do not use gasoline or solvents to clean the
filter; this could cause a fire in the fuel system. Use
only a fire-proof solvent or detergent. This can cause
serious burns or destruction of your vehicle.
REMOVAL
Raise the fuel tank, see 2.8 (LIFTING THE FUEL
TANK).
Unscrew and remove the seven fastening screws (1)
holding the filter case cover (2).
Tightening torque for screws (1): 1.47 ftlb (2 Nm).
Remove the filter case cover (2).
Extract the air filter (3).
WARNING
Thoroughly clean the air filter seat on the filter box to
remove any foreign matter. Plug the throttle body and
air filter seat openings with clean rags to prevent any
foreign matter from entering the intake tubes.
Make sure the gasket (5) is intact; replace if damaged.
PARTIAL CLEANING
WARNING
Do not press down or beat on the metal screen of the
air filter (3). Do not use screwdrivers or similar tools
on the filter itself.
Hold the air filter (3) upright and strike it repeatedly
against a clean surface.
If necessary, clean the air filter (3) with a blast of
compressed air (aiming it outwards from inside the filter).
Clean the outside of the air filter (3) with a clean cloth.
CHANGING
Replace the air filter (3) with another of the same kind.
Every 7500 km (4687 mi), remove the plug (4) and
remove any dirt that may have settled inside the filter
case.
WARNING
Check the filtering element while cleaning to make
sure there are no tears. If so, replace the filtering
element. Make sure that the filtering element is
correctly positioned so that it does not allow any
unfiltered air to pass through. Remember that early
wear on the piston rings and cylinder is often caused
by a faulty or poorly positioned filtering element.
Clean the filtering element more often if the vehicle is
used in dusty areas. Using the vehicle without the
filtering element, or with a damaged element, will
considerably increase wear and tear on the engine.
Make sure that the filtering element is always in
perfect condition, as long engine life depends on the
air cleaner being in perfect condition.
