Engine air filter
The efficiency and life of the engine depend greatly on
the quality of air taken in. A dirty or damaged air filter
can seriously affect the correct working of the engine
and increase the possibility of a fault.
Replace the air filters strictly according to the schedule
indicated in this Manual. Do not try to wash dirty
filters.
If the vehicle is expected to be used in environments
with a lot of dust or high concentrations of
contaminating or polluting agents in the air, halve the
time interval between one filter replacement and the
next.
Replacing the primary cartridge
Set the vehicle in the parking position. Rotate the
turret to the left through 45° to allow easier access to
the filter housing.
Lift the protective cover on the locking mechanism and
then use the key to open the trap-door and lift it to
access the filter compartment.

Wipe thoroughly inside the filter housing with a damp
cloth. Avoid the use of aggressive solvents or products
as these can damage the safety filter or the filter
housing.
Install a new filter element. Make sure the filter
element is inserted properly in its seat. If installation is
difficult, grease the rubber gasket
