Professional Kawasaki Mule 3000 3010 3020 2x4 4x4 Repair & Maintenance Manual
It is simply well worth the price.
This is a must-have manual for any Mule owner. It is easy to search and does an excellent job of illustrating it's descriptions. The cost is tiny compared to buying a printed manual from Kawasaki.

A much more affordable alternate to the hard copy manual. Every Mule owner should have this.
