This manual contains information and data to this model. Has specs, diagrams, and actual real photo illustrations, and schemes. These service manuals are useful for both professional mechanics and DIY enthusiasts. In addition to space savings, the nice thing about having files instead of a hard-printed manual is that you can use the Search feature in Acrobat to find just what you're looking for and just print out the exact pages you need... or all manual.
Please, write me if you have questions. Probably I have the manual which you for a long time search. Have a nice day.
