These service manual is as good as it gets for Diagnosing, Repairing, and Maintenancing Hitachi machinery. In addition to space savings, nice thing about having PDF files instead of a hard-printed manual is that you can use the Search feature in Acrobat to find just what your looking for and just print out the exact pages you need... or all manual.
