What's in it

It begins with general specs, weights and dimensions. The structure and function chapter covers the hydraulic pump, control valve, PPC valves, swing and travel motors, cylinders and electrical system. Testing, adjusting and troubleshooting gives you the pressures and speeds to check against, then the disassembly and assembly procedures. The maintenance standards and wear limits are at the end.

Small machines like this are often owned by landscapers and utility contractors who do their own servicing, or run in rental fleets. The book helps with the common jobs: slow travel, swing that won't hold, weak digging and worn pins and bushings.

Good to know

If you're new to Komatsu manuals, the layout takes a few minutes to learn and then saves a lot of time. Each system is covered in the same order: how it works, the values it should meet, how to test it, and how to take it apart. Search works on most pages, and printing one procedure for the job keeps the rest of the book clean.
