The user is responsible for the performance of maintenance, including all adjustments, the use of proper lubricants, fluids, filters. The user is also responsible for 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, in order 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.
