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.

Before each consecutive interval is performed, all maintenance from the previous intervals must be performed.

Choose the interval that occurs first to determine the correct maintenance interval: fuel consumption , service hours, and calendar time. Products that operate in severe operating conditions may require more frequent maintenance.

Ensure that all safety information, warnings, and instructions are read and understood before any operation or any maintenance procedures are performed.
