Maybe it's a language issue and if so, I do apologize, but why was a new document created? Why not simply create a controlled version of the existing document? Or was there information on the uncontrolled version that needed to be incorporated into a new version?
Either way, the standard does not tell you how to train. What it looks for is effectiveness of the training usually demonstrated through competence. Competence can be measured by any nonconforming outputs of the process.
So, if the document is "How to Operate Machine B"...and the team(s) that use Machine B have 0-some organizationally-determined acceptable number/rate of defective products, then essentially have competence, meaning the training was adequate.
