MAINTENANCE
Regular scheduled maintenance lowers operating costs and lengthens the service life of the generating set. Use
the following guide to establish effective service periods. However, actual conditions under which the unit
operates is the determining factor in establishing a maintenance program. When operating the unit in very dusty or
dirty conditions, some of the service periods may have to be reduced. Check the condition of the crankcase oil, the
filters,
etc., frequently until proper service time intervals can be established.
For any.abnormalities in operation, unusual noises from the engine or accessories, loss of power, overheating,
etc., contact your nearest Onan dealer.
