SECTION V MAINTENANCE
Cleaning the air filter
Clean the filtering element whenever the air filter warning light
comes on.
Important
It is important to make sure that the warning light is always working
correctly. To check its operation, start the engine and temporarily obstruct
the air filter intake tube (do not use your hands). The filtering element must
always be in perfect working order; if not, clean, wash or replace it.
Cleaning the filter using compressed air
This is the correct cleaning method to use when the filter is clogged with
dust. Direct a jet of compressed air (max. pressure 6.8 bar/98 psi) from the
inside to the outside of the element, moving the jet along the pleats in the
paper until all the dust is removed.
Washing the filter element in water
This cleaning method is particularly recommended when the the filter
element is clogged with oil substances. Wash the element using a jet of
clean water (max. pressure 2.9 bar/42 psi) directed from the inside to the
outside of the element. Leave the element to dry in a dust free
environment for 24 hours.
Refitting the element
Wipe out the air filter casing with a dry rag, and check that the element is
not deformed. Hold a light inside the paper element to check for tears or
holes in the paper fabric.
The filter element must be replaced after being cleaned 6 times, unless
any small holes or tears are detected sooner, in which case it must be
renewed immediately.
The inner safety element must never be cleaned. It must, however, be
replaced after the main element has been cleaned 3 times.

NOTE: Never use gasoline (petrol), kerosene or cleaning solvents to clean
the element.

- never add oil to the dry air filter element.

otherwise engine could lose power and damage to engine could occur.
- never use a filter that shows sign of damage.
If in doubt, replace the filter.
