The Kobelco SK260-9, SK295-9 service manual PDF fits both hydraulic excavators in this pair: 962 pages under OEM ID 84531464, running from the Mechatro controller to the front idler and track adjuster. Operational principle fills more than a third of the book, where hydraulic schematics trace oil from the main pump through the control valve and pilot circuit, and wiring diagrams map the electrical system. Troubleshooting runs by error code and by symptom, and the repair chapters walk you through swing bearing, travel device, swivel joint and cylinder teardown, ending with front attachment maintenance standards. Set your test gauge against a main pump rated pressure of 34.3 MPa (4980 psi), and on the SK260-9 expect 655 N·m (483 lbf·ft) of swing motor braking torque. Out on site, there is often nobody to call. Bookmarks land you on the right chapter fast, and the text layer finds any component name in seconds.
