Hi Buz,
there is an Operators manual, a Technical manual, a Parts manual as well as the Workshop manual. I have the first three but not the Workshop manual My understanding is that the Workshop manual covers a range of models. You can get the parts and operators manual downloads on the internet.
I had to send away for the technical Manual ( Plough Books in Australia).
The workshop maual is the most expensive and from the excerpts I have seen, not that great.
If you find one under $50, let me know.
