Check torque on all threaded fasteners (initial torque check should be at 100 hours on new or rebuilt equipment); 4. Change engine oil/filter and change brake oil; 5. Clean radiator/oil cooler and other cooling system; 6. Grease (steering cylinder)/lubricate all grease fittings plus all hinges, pivots, etc.; 7.
