IMPORTANT
- These recommendations are es-
sential. The observation of these recommenda-
tions will prolong the life of your engine and will
affect the applicability of the guarantee, which is
provided.
- Do not make any unauthorised modifications to
the engine.
- Damage caused by the use of parts not bearing
a manufacturer’s reference number are not cov-
ered by the warranty
- The repairs and maintenance must be carried
out by an authorized NANNI DIESEL workshop.
If the engine is used for a number of hours less
than the number specified for maintenance inter-
vals, then maintenance must be performed at
least once a year.
In this case, it is recommended that maintenance
be performed before winter storage. New, clean
lubricants will thus protect the engine.
Valves adjustments
