• 80 AIR CONDITIONING — Refrigerant precautions, component layout, refrigeration cycle, air conditioner unit, dual pressure switch, controller, compressor, condenser, receiver drier, sensors, testing and troubleshooting (self-diagnosis, vent changeover, FRESH/RECIRC, sunlight sensor, pressure switch, relay), gauge pressure diagnostics, refrigerant piping and compressor oil handling
• 90 DIAGRAMS AND DRAWINGS — Hydraulic circuit symbols and diagram, electrical circuit symbols, electrical circuit diagrams (1/6 to 6/6) and air conditioner electrical circuit

Every chapter is written as a working reference, not a summary. The structure and function section explains how each hydraulic and electrical system actually operates on these specific machines, including the CLSS closed-centre load-sensing system, the LS and PC valve behaviour, the EPC valve operation, and the KDPF regeneration strategy. The testing and adjusting section gives the exact tools, measuring conditions and target values required before a repair can be judged correct. The troubleshooting section pairs failure codes with a numbered diagnostic sequence so a technician can move from symptom to root cause without guesswork. The disassembly and assembly section provides step-by-step removal, installation, disassembly and assembly procedures with tightening torques, coating materials and special tool references throughout.

What This Manual Enables You To Do

This shop manual supports the complete range of professional work on the PC360LC-10 and PC390LC-10: engine and cooling system service including KVGT, EGR, KCCV and KDPF components; hydraulic pump, control valve, LS/PC/EPC valve diagnosis and adjustment; swing and travel motor overhaul; final drive and swing machinery disassembly and assembly; undercarriage inspection and component replacement; work equipment cylinder repair; electrical troubleshooting with full circuit diagrams; machine monitor and controller diagnostics; and air conditioning system testing, repair and refrigerant handling.

The value here is having the correct procedure and the correct specification at the same time. A hydraulic relief pressure adjustment, a pump swash plate sensor calibration, a valve clearance setting, a final drive preload or a wiring harness diagnosis all depend on values and sequences that are only meaningful when they come from the manufacturer’s own reference. This manual provides those values and sequences in one place, organised by system and by symptom, so the diagnosis can be confirmed before any parts are ordered or any assembly is closed up.
