open fill valve (9) that is located between the hydraulic tank and the implement pump.
9. Attach a bleed line to pressure tap (10) that is located in the case drain line above the fan
pump.
10. Begin filling the hydraulic tank with oil. Once oil begins to flow out of the bleed line,
remove the bleed line and fully close the fill valve.
11. Continue to fill the hydraulic tank to the correct level. Refer to Operation and Maintenance
Manual, "Hydraulic System Oil - Change".
