Part of the Hyundai Repair Manuals.
Looking for the Hyundai R210LC-7H, R220LC-7H service manual PDF? All 484 pages cover the ROBEX 210LC-7H and 220LC-7H hydraulic excavators, from pump device teardown to final track tension adjustment. Inside: full hydraulic circuit schematics with pilot and main circuit routing, complete electrical wiring diagrams with connector pinouts, and a full troubleshooting section for hydraulic, electrical, and mechatronics faults. You also get disassembly and assembly procedures for the main control valve, swing device, travel device, and turning joint, backed by mounting torque tables for every system. Fill the hydraulic tank to 180 L (290 L total system) and torque the track roller mounting bolts to 54.7 kgf-m. No more chasing a swing fault through your cab harness with forum guesses. Bookmarked with a full text layer; jump to any section, search any spec, and get wrenching.
