Chapters Covered

• Section 1 General – Specifications, Working Ranges (Loading Shovel and Backhoe)
• Section 1 General – Component Layout (main components, electrical system overview, cab, battery, relay box, electrical equipment box, monitoring controller box, engine, air cleaner, radiator, oil cooler, pump area, control valve, pilot panel, EDQR valve, swing device, undercarriage, travel device, center joint, fast-filling system, folding stairway, auto-lubrication device, hydraulic oil tank, fuel tank)
• Section 1 General – Component Specifications (engine, engine accessories, hydraulic components, electrical components, others)
• Section 2 System – Controller, Control System, ELU System, Hydraulic System, Electrical System, Air Conditioning System
• Section 3 Component Operation – Pump Device, Swing Device, Control Valve, Control Equipment, Travel Device, Others (Upperstructure), Others (Undercarriage), Others (Front Attachment)

Together these sections walk a technician from the machine’s overall specifications and working dimensions through every controller and hydraulic circuit, down to how individual valves, pumps, and cylinders actually function inside the EX2600-7’s systems.

What’s Inside the Engine and Hydraulic Data

The Cummins FCO engine section lists the QSKTA50-CE as a 16-cylinder, 60° V, water-cooled, direct injection, exhaust turbocharged diesel with a 50 L displacement, rated output of 1119 kW/1800 min-1, and a 15.0:1 compression ratio, along with cooling system, lubrication, starting, alternator, and fuel system data. The hydraulic component tables cover the main pump drive ratios, swash-plate variable displacement pump displacements, control valve relief pressures, swing motor and travel motor specifications, and boom/arm/bucket cylinder bore, stroke, and rod diameters for both the Loading Shovel and Backhoe front-end configurations.

Why This EX2600-7 Manual Matters

Understanding how the EX2600-7’s pump flow control, ELU electric lever system, and hydraulic circuits operate is what lets a technician correctly interpret symptoms before chasing the wrong component. This Technical Manual – Operational Principle gives you the factory-documented operating logic behind the machine’s controllers, pumps, valves, and electrical system, using the same specifications and terminology Hitachi technicians rely on for the EX2600-7.

With this manual you can:

• Understand how the pump flow control, ELU, and monitoring systems interact on the EX2600-7
• Reference exact engine, hydraulic, and electrical component specifications during diagnosis
• Study the swing device, travel device, and control valve operating principles before disassembly
• Confirm cylinder, motor, and valve pressure specifications for the Loading Shovel or Backhoe configuration
