Following Is arecommended maintenance schedule for stationary emergency diesel engine driven generator sets from 500 kW to 600 kW in size. The established intervals in the schedule are the maximum required when the unit is used in an average service application. They will need to be decreased (performed more frequently) if the unit is used in a severe application.
