Hi fastback. Sorry, I don't have one and have never seen one (manual, that is).
I've fiddled with mine a bit and like it. The two issues I have are slowing it down, and reproducing a hold-down for the work. Neither seems difficult, just take some time and money, both of which are in short supply at the moment.
I'll try to answer any questions you have, to the best of my meager ability
Hello Sea Farmer, I noticed that you also have a Keller Die Filer. I was just given one and its a model 256. I was wondering if you happen to have a copy of the owners manual. Mine is pretty complete with both of the upper arms. BTW, I also live in Southeastern MA.
