Maintenance
500 KW TO 600 KW STATIONARY EMERGENCY DIESEL ENGINE DRIVEN
GENERATOR SETS
Following Is a recommended 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. Use the unit hour meter or calendar time, whichever
occurs first, from the previous maintenance interval to determine the next required maintenance interval.
NOTE: Add 20% to all times noted for 12 cylinder or larger engines.
