The user is responsible for the performance of maintenance. All adjustments, the use of proper lubricants, fluids, filters, and the replacement of components due to normal wear and aging are included. 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, in order to determine the maintenance intervals. Products that operate in severe operating conditions may require more frequent maintenance. Refer to the maintenance procedure for any other exceptions that may change the maintenance intervals.
Note: The aftertreatment system can be expected to function properly for the useful life of the engine (emissions durability period), as defined by regulation. All prescribed maintenance requirements must be followed.
Note: Before each consecutive interval is performed, all maintenance from the previous interval must be performed.
Note: If Cat HYDO Advanced hydraulic oils are used, the hydraulic oil change interval may be extended substantially. S·O·S services may extend the oil change even longer. Consult your Cat dealer for details.
The following guidelines should be followed if the service hours are not met:
Items listed between 10 and 100 service hours should be performed at least every 3 months.
Items listed between 250 and 500 service hours should be performed at least every 6 months.
Items listed between 1000 service hours and 2500 service hours should be performed at least every year.
