Description
This is the Illustrated Parts Manual for the KX121-2 Kubota Mini Excavator. It contains all the parts information required to properly lookup part numbers for the entire machine, including engine parts.
- Illustrated Parts Manual: 309-Pages
Easy to read exploded views are provided to facilitate easy number identification, aiding in careful disassembly, accurate ordering, and ultimately correct repairs. All sections are neatly organized in Adobe Acrobat, featuring very clean, sharp images that are scalable to several times normal size. The manual includes tons of crystal clear exploded views, diagrams, and accessory information.
This manual is exactly like the paper manual made for this equipment; the only difference is that this one is not paper and doesn't need to be shipped. You can access it immediately! Zoom it, print it, save it, and close it. Print a few pages at a time as you need; no need to lug that bulky binder around anymore!
Upon purchasing the manual, you will immediately receive a link in your email. Simply click the link to view, print, and save it for later use. It can be viewed in the popular Adobe format, which is supported by most computers. For the latest FREE Adobe viewer, visit www.adobe.com.
