Part of the Hitachi Repair Manuals.
Factory repair manual for the Hitachi -5 series: EX200-5, EX200LC-5, EX220-5, EX220LC-5, EX230LC-5, EX270-5 and EX270LC-5 hydraulic excavators. This is the workshop-level book, not the operator handbook. It covers system operation and component function for the hydraulic and electrical circuits, performance testing with fault diagnosis and adjustment procedures, then full teardown coverage of the upperstructure (swing device, main pump, control valve), undercarriage (travel device, track components, track adjuster), front attachment (boom, arm, bucket linkage) and the Isuzu engine with cooling, lubrication and fuel systems. If you are chasing a sluggish boom, a stuck engine RPM or a fault code 07, this is the same reference a Hitachi dealer tech would open before touching the machine.
