The user is responsible for the performance of maintenance, including all adjustments, the use of proper lubricants, fluids, filters, and the replacement of components due to normal wear and aging. Failure to adhere to proper maintenance intervals and procedures may result in diminished performance of the product and/or accelerated wear of components.
Use mileage, fuel consumption, service hours, or calendar time, WHICH EVER OCCURS FIRST, to determine the maintenance intervals. Products that operate in severe operating conditions may require more frequent maintenance.
Note: Before each consecutive interval is performed, all maintenance from the previous interval must be performed.
The following factors will affect the oil change interval: operating conditions, fuel type, oil type, and size of the oil sump. Scheduled oil sampling analyzes used oil to determine if the oil change interval is suitable for your specific engine.
Refer to this Operation and Maintenance Manual , "Engine Oil and Filter - Change" to determine the oil change interval that is suitable for your specific engine.
To determine the maintenance intervals for the overhauls, refer to this Operation and Maintenance Manual , "Maintenance Recommendations" .
Unless other instructions are provided, perform maintenance and perform repairs under the following conditions:
The starting system is disabled.
The engine is stopped.
The generator does not pose an electrical shock hazard.
The generator is disconnected from the load.
