It's been a while since I last posted, 7 years to be exact, but I pre-inherited (my parents are still alive) my dad's Stihl chain sharpener. He bought it in 1984 and low and behold it still runs, my parents have a tool rental business that they are liquidating and I got the sharpener. Part of me can't believe it still works as electric motors don't typically last 30+ years but I don't have the manual, so I was looking for advice on settings, or a copy of a manual? I looked online and the manual for the newer model references a tech sheet for set-up but I can't find the tech sheet online. Any help would be greatly appreciated. Side note: I think it's pretty cool to have a working tool that's stamped: made in western germany. It's pretty dirty but I'll post some pics if anyone's interested.
