ENGINE MAINTENANCE
The maintenance operations are subdivi-
ded into:
– Maintenance during running-in (rst 50
hours)
– Routine maintenance (after running-
in) The frequency stated in the “ routine
maintenance” table should be applied to
engines which are used regularly.
Some lubricants or components lose
their characteristics over time even if the
engine is left idle for long periods; the-
refore, maintenance intervals should be
established considering that these parts
need to be replaced not only on the basis

The approximate maximum time during
which the chemical-physical characteristi-
cs of a few components or lubricants are
maintained is stated below.
– 1 year – Lubricant oil
– 1 year - Fuel lter cartridge
– 2 years - Cartridges, air and oil lter
– 2 years – Coolant
