What's in it

After the general specs and fluids, section 10 covers the engine-related parts, power train, final drive, swing circle and machinery, rollers, track shoes, hydraulic pump, LS-EPC and control valves, swing motor, center swivel and work equipment. The blade option is covered too.

Section 20 gives the standard values, pressure checks, adjustments and troubleshooting. Section 30 covers disassembly and assembly of the main components, and section 90 has the circuit diagrams.

Short-tail machines spend a lot of time slewing in confined spaces, so the swing machinery and swing motor get plenty of use. The LS-EPC valve pages help when the machine feels slow or unresponsive.

Good to know

Most people use a book like this one section at a time. Look up the system that's giving trouble, read how it's meant to work, test it against the standard values, and only then order parts. That order saves money, because a reading that's close to spec usually points somewhere other than the part you suspected first. You can print the pages for the job and keep the PDF on a tablet for everything else.
