Daily and periodic inspection are important to keep the engine in its best condition.
The following is a summary of inspection and servicing items by inspection interval.
Periodic inspection intervals should vary depending on the uses, loads, fuels and lube oils used
and handling conditions, and are hard to establish definitively. The following should be treated
only as a general standard.
Schedule your own periodic inspection plan according to the operational conditions of
your engine and inspect every item. Neglect of periodic inspection may lead to engine
troubles and shorten the life of the engine. Inspection and servicing at 2000 hours of
operation and thereafter require special knowledge and techniques.
Consult your dealer or distributor or the Yanmar subsidiary in your region.
