What's in it

Section 10 covers structure, function and maintenance standards for the engine and cooling, HST power train, axles and differentials, steering, brakes, undercarriage and frame, hydraulics, work equipment, cab and electrical. Section 20 is the standard value table, and section 30 gives the testing and adjusting procedures.

Section 40 has the failure code table and the fuse locations, then electrical (E-mode), hydraulic and mechanical (H-mode) and engine (S-mode) troubleshooting. Section 50 covers disassembly and assembly, and section 90 has the circuit diagrams.

An HST loader is smooth and efficient, but drive complaints need the right test values to diagnose. The fuse location pages are a small thing that saves a lot of time.
