This is the factory Mustang ME8002 Service Manual, part number 918173, a 156 page PDF covering the ME8002 compact excavator powered by the Yanmar 4TNE98-NSR diesel engine.
It carries the full workshop content a mechanic needs: technical data and lift capacities, scheduled maintenance and lubrication, the complete hydraulic system with pump, pilot oil supply, and main and secondary valve blocks, diesel engine service items, electrical wiring diagrams, operating elements, and torque specifications. Hydraulic settings, engine idle speed, valve clearances, and fitting torque values are listed with the pages that carry them.
Whether you are chasing a hydraulic fault, setting track tension, or rebuilding a valve block, this manual lets you diagnose and repair the machine yourself instead of guessing. It is a searchable PDF you can download now and print any page you need at the bench.
