Air intake and exhaust gas circuits
Inspect the cleanliness of the air intake circuit on a regular basis. The
maintenance intervals indicated in this manual vary according to the
conditions in which the engine is operated.
In particularly dusty environments the maintenance frequency must be
increased from that shown in section CHECKS AND
MAINTENANCE.
Electric ignition system
Periodically check, particularly during the winter, to ensure that the
batteries are clean and in full working order, checking and topping up
as indicated in the CHECKS AND MAINTENANCE section.
In the event of battery replacement, observe the characteristics
contained in the ENGINE TECHNICAL DATA chapter.
Battery or alternator recharging faults
Periodically check the cleanliness, condition and correct tensioning of
the drive belt.
RUN-IN
Thanks to the new engine technology, no running-in is required.
ATTENTION!
Visually check that the exhaust circuit is not blocked or
damaged, so as to prevent dangerous fumes.
Contact a specialised workshop and check battery and
recharging system efficiency if the voltmeter indicates a
voltage below 11 V (for 12 V rated systems), or 22 V
(for 24 V rated systems).
ATTENTION!
The batteries contain an acid solution that will burn the
skin and corrode clothing; when checking them, always
wear protective clothing, gloves and goggles, do not
smoke or use live flames in the vicinity, and make sure
that the room they are housed in is adequately
ventilated.
ATTENTION!
The auxiliary units are located under protective grilles.
Their removal must be carried out only when the
engine is not turning.
