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

The user is responsible for the performance of all maintenance which includes the following items: performing all adjustments , using proper lubricants, fluids, and filters and replacing old components with new 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.

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

Choose the interval that occurs first in order 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.

All of the following will affect the oil change interval: operating conditions , fuel type , oil type and size of the oil sump . Scheduled oil sampling analyzes used oil in order 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" in order 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" .
