What is the story with service manuals. Have been looking for a free (or small charge for a) service manual for my YS828, and all the links in this forum are broken or erased. There is a post on Dec.15, 2013 entitled MANUALS""""MANUALS""""MANUALS that purports to have all the manuals, but there is nothing useful there. I have found a Power Products offering, for what may be the manual, for $94.72, but that is a bit too much.
I google-searched galore with the same result.
I'm starting to think they are classified, and the NSA has deleted them. :-)
