All 782 pages of this Fiat Kobelco E40.2SR, E50.2SR shop manual PDF (OEM #604.13.368) focus on one job: bringing your short-radius hydraulic excavator back to factory spec. You get complete hydraulic circuit diagrams, electrical schematics with harness connection charts, and troubleshooting trees that walk hydraulic, electrical, and engine faults down to the failed part. Inside: teardown and reassembly procedures for the attachments, upper slewing structure, travel system, and the engine itself, backed by torque tables for capscrews, joints, hoses, and sleeve-type tube fittings. Set the piston pump working pressure at 23.0 MPa (3340 psi), then torque the relief valve nut to 19.6 N-m before you button it up. No more chasing a pressure fault with borrowed numbers. Bookmarked with a live text layer, so you can jump to any section or search a spec right from your phone at the machine.
