Part of the Hitachi Repair Manuals.
All 718 pages of this Hitachi Zaxis 160W, Zaxis 210W workshop manual PDF focus on one job: complete teardown and repair of your wheeled hydraulic excavator, from cab to counterweight. You get full electrical circuit diagrams tracing the battery, starter, glow relay, main controller, and fuse box, plus hydraulic schematics mapping the main pump, control valve, swing motor, and every cylinder on the front attachment. Inside: step-by-step procedures for the travel motor, swing bearing, center joint, transmission, axles, and brake valve, and a full engine section running from assembly through turbocharger, fuel system, and troubleshooting. Torque the control valve mounting bolts to 210 N-m (152 lbf-ft), and swap the pump suction hose every 2 years per the maintenance chart. No more chasing wiring faults with a multimeter and a prayer. Bookmarked and keyword-searchable; jump straight to the spec and get your machine back on its wheels.
