Service Maintenance Intervals
Extended Run-Time Maintenance Checks
Daily checks which must be performed when the unit is operated continuously for extended periods of time. These checks and routine monthly checks can be performed by an authorized operator.Note: For units equipped with a gearbox, the gearbox oil should be checked monthly or every 100 hours of operation.A one time post installation, initial operation, service inspection of the generator set to ensure that generator is ready to operate, transfer to, and carry the load when required, and to identify any potential problem areas.Note: Performed only once following the first 3 months or the first 50 hours of operation after installation/startup of the unit and requires approximately 2.5 hours per unit to complete.The various service maintenance intervals are designated by interval numbers:
A frequent, periodic inspection of the generator set to ensure that generator is ready to operate when required and to identify any potential problem areas. Performed monthly, or every 24 hours (interrupted) of operation of the unit, and requires approximately 0.5 hours per unit to complete.
An operational service inspection of the generator set to ensure it is ready to operate and carry the load when required, and to identify any potential problem areas. Performed semi-annually (6 months) or every 125 hours of operation of the unit and requires approximately 1.5 hours per unit to complete.
A mid-level service inspection of the generator set to ensure that generator is ready to operate and carry the load when required, and to identify any potential problem areas. Performed annually or every 250 hours of operation of the unit and requires approximately 6.0 hours per unit to complete.
A comprehensive service inspection of the generator set to ensure that generator is properly serviced and ready to operate and carry the load when required, and to identify any potential problem areas. Performed biannually (every 24 months or 500 hours) and requires approximately 8.0 hours per unit to complete.Note: Maintenance levels 2, 3, and 4 require the use of the applicable engine service manual and must be per- formed by a qualified service technician.Maintenance Schedule
The following contains the maintenance schedule describing the checks/tasks which need to be accomplished at each designated maintenance interval. Some maintenance level tasks are combined. For example, if the 6-month tasks are due, both the monthly and the 6-month task should be completed at the same time. Similarly, when the annual tasks are due, the monthly and semi-annual tasks should also be completed. There is space on the sheets for recording the date and signature of the person completing the task, as well as recording the engine hours and other pertinent information. At the bottom of each sheet, space is also provided to record any fluids added, parts replaced or corrective action taken. All this recorded information provides a detailed maintenance history of the unit. This maintenance his- tory may be required for warranty validation purposes, and is a good idea to maintain throughout the lifetime of the unit.It is recommended by the manufacturer that service procedures beyond the normal monthly checks be performed by an Authorized Service Dealer
Table 1
Maintenance Item Description
Oil and Oil Filter Change oil and filter shortly after start-up or commissioning of the unit. The recommendation is that oil and oil filter change to be done after the first 50 hours of operation or after the first 3 months of service. Perform oil and filter changes every 250 hours (or yearly) thereafter. If an oil analysis program is used (annually), the acceptable oil change interval can be extended to 500 hours or every 2 years, based on the results of the analysis.
Coolant Quality Check coolant annually for proper thermal protection levels. Drain, flush, and refill the cooling system with fresh coolant every 2 years regardless of operating hours.
Flexible Hoses Change coolant, fuel (gaseous supply hoses from regulator to mixer), oil, charge air cooling, and block heater hoses, flexible joints) every 2 years regardless of operating hours.
Accessory Drive Belts Replace accessory drive belts every 2 years regardless of operating hours. If necessary, check and replace automatic tensioner (if used).
Magnetic Pickup mounted on flywheel housing Remove, clean, inspect, and reset magnetic pickups to the correct operational output voltage every 2 years.
Crank and/or Cam Pickup for ignition system Visually inspect (outside) for cleanliness and tightness. Note: Certain applications may require more frequent maintenance checks and more frequent operation under load.Note: This schedule does not reflect all the possible requirements of an individual engine manufacturer service schedule, particularly if the unit is used in other than a standby power application.Note: For more information about service schedules and support for your application, consult your local Authorized Service Dealer.Extended Run-Time Maintenance Checks
These maintenance tasks should be performed by a trained authorized operator. Comply with all safety notices contained in the Owner Manual.Note: Perform steps 1 through 12 and 14 every 24 CONTINUOUS operating hours. These checks require approximately 0.5 hours per unit.
