What's in it

The structure and function chapter covers the hydraulic pumps, the control valve, swing and travel, and the logging work equipment, which is where this machine differs from a standard excavator. The electrical system and sensors have their own chapter. Testing, adjusting and troubleshooting gives you the factory pressures and fault-finding steps.

The rest of the book is disassembly and assembly and the maintenance standards with wear limits, across 332 pages.

Forestry machines put in long hours in rough conditions, and logging attachment hydraulics take a beating. Logging contractors and forestry equipment dealers will use the troubleshooting chapter most, along with the wear limits when planning a rebuild over the off-season.

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.
