It begins with the safety rules, battery and electronic system basics, torque tables, abbreviations and machine capacities that apply across the whole machine, then moves into the three major system groups. The hydraulic content covers component identification, removal and installation, disassembly, inspection, assembly, pressure and flow testing, leakage testing and diagnostic flowcharts for every major hydraulic circuit. The electrical content covers the connector layouts for each harness on the machine, pinout tables, and full electrical schematics for every circuit from power distribution and starting through to the pilot controls, heavy lift and DIA kits, followed by alternator and battery service.
