Part of the Hitachi Repair Manuals.
Three Hitachi factory books bound into one 1,552-page PDF for the ZAXIS-3 family - ZX110-3, ZX110M-3, ZX120-3, ZX130K-3, ZX130L-3, ZX135US-3, ZX135USK-3 and ZX135USL-3.
Pages 1-334 are the Technical Manual Operational Principle: specifications, component layout and specifications, then the controller, control system, ECM and hydraulic and electrical systems, component operation for the pump, swing and travel devices and control valve, and the operational performance test. Pages 335-1030 are the Technical Manual Troubleshooting: the diagnosing procedure, the monitor unit, the Dr. ZX dealer tool, E-Shovel, fault codes, Troubleshooting A and B and the electrical system inspection. Pages 1031-1552 are the Workshop Manual: removal, disassembly and assembly for the upperstructure (cab, counterweight, main frame, pilot shut-off), the undercarriage (swing bearing, centre joint, track adjuster, final drive) and the front attachment.
On diagrams, precisely: the control side is illustrated here - page 155 is the ECM system diagram with the main controller, the CAN link, engine sensors, common rail and injector - and the hydraulic section explains the pump control circuits. The full fold-out sheets, however, were attachments to the printed manual: page 1030 lists them (electrical circuit diagram, connector charts, cab, engine, monitor, air-conditioner and switch harness drawings, and the hydraulic circuit diagram including the blade option) and they are not part of this PDF.
