4.Inspect the tractor for leaks hourly during the first 10 hours of operation..

5.Torque the wheel bolts to 715 N·m (525 ft-lbs) after the first hour of operation and after every three hour of operation for the first day.. Re-tighten to the specified torque daily until wheel hardware maintains the specified torque..

6.Operate the engine at 3/4 load as much as possible during the first 50 hours (3/4 load is approximately one gear lower than would be normally used to pull a matched load)..
