This is the factory Takeuchi TB260 workshop manual (publication CQ1E001) for mini excavators from serial number 126100001 and up, powered by the Yanmar 4TNV86CT diesel engine. It runs 702 pages and is written for the technician who actually pulls the machine apart, not a quick-start leaflet.
Inside you get service data with torque tables and hydraulic and electrical circuit diagrams, function descriptions of the piston pump, control valve and pilot valves, full disassembly and assembly procedures for the travel system, hydraulic pump, cylinders and slew motor, plus a troubleshooting section organized by symptom across traveling, slewing, boom, arm, bucket and blade.
With it you can diagnose weak hydraulics, rebuild a leaking cylinder, set correct tightening torques and trace a wiring fault back to the harness. Delivered as a downloadable PDF you can read on any device or print.
