NOTICE
When the main hydraulic pump has been serviced or the hydraulic oil has been replaced, the air in the hydraulic system must be purged. Do not start the engine until the main hydraulic pump has been filled with oil. Operating the hydraulic pump without proper lubrication will damage the pump and other hydraulic components.

17. Fill the hydraulic oil tank with hydraulic oil to the correct level. Refer to Operation and Maintenance Manual, "Lubricant Viscosities" for the proper oil viscosity. Refer to Operation and Maintenance Manual, "Refill Capacities" for the correct amount. Refer to Operation and Maintenance Manual, "Hydraulic System Oil Level - Check" for the correct filling procedure.

18. Install high efficiency filters in place of the pilot filter, the filter for the case drain, and the return filter.

    Note: High efficiency filters should not be run for more than 250 hours before you change back to the standard filters.
