Everything in the manual was excellent except for a couple of pictures of specific areas in the unit that were a little dark. Owners Manuals re-sent the pdf file & the problem was corrected. Excellent product! George
This is the original manufacturers service manual, with detailed info on the circit boards, explosion drawings of all parts in assembly order, and tuning instructions. The only thing missing is the information on the dimensions of the various drive belts. mail me if you need them. gcrossman_at_aol.com
This is a high quality manual with clear schematic and components layout diagrams ; with service procedure included.
