Part of the Hitachi Repair Manuals.
This is the factory workshop manual set for the Hitachi ZAXIS 200, 225US, 225USR, 230 and 270 excavators built from 2003 to 2013, including the separate engine sub-manual for the Isuzu-based diesel. You get full disassembly and reassembly procedures for the pump device, control valve, swing device, travel device, center joint, swing bearing, track adjuster and all boom, arm and bucket cylinders. Real torque values are printed where you need them - 210 N.m on the hydraulic tank mounting bolts, 90 N.m on the swing motor bolts, 360 N.m on the upper engine cushion rubber bolts. The air bleeding procedure alone is worth the download if you have ever had weak hydraulics after a pump or hose job.
