If more detailed maintenance information is required, it can be found in the individual service sections.
- Section 2 covers the undercarriage. It includes the turntable bearing, the tracks and the track drives.
- Section 3 covers the mechanical components of the upper structure. Included are the engine, pump drive transmission, the swing assemblies and the boom assembly.
- Section 4 covers the Electrical System. It is divided into the charging system, lights and instrument circuits, and the control circuits.
- Section 5 covers the Hydraulic System. it includes the main system, the pilot control system, the counterweight system, the supercharge system, and the auxiliary hydraulic system.
The sections are divided into two subdivisions. The first part covers description, maintenance and troubleshooting. The second part covers disassembly and repair.
