Need advice with a problem with odhner 39 revolution counter reset handle jammed and not able to turn it can only be made to work and freed up by replacing zeros with any number on all wheels except the outside two at either end, have tried retiming with no luck any one any ideas please
Sorry for not getting back to you. All the cranks were jammed. I suspect that the machine had been oiled at some point and that the oil had hardened. I manage to un-jam the cranks by adding _more_ oil and carefully pulling/pushing the lever. To my surprise, that resolved the issue.
