Note: Use distance (odometer), fuel consumption, service hours, or calendar time, WHICHEVER OCCURS FIRST , in order to determine the maintenance intervals. Engines that operate in severe operating conditions may require more frequent maintenance. Failure to adhere to proper maintenance intervals may result in degradation of engine performance and/or accelerated engine component wear.
Before each consecutive interval is performed, all of the maintenance requirements from the previous interval must also be performed.
