It doesn't have power down. But if it has a lever and a crank wheel then I would think there both suppose to work. But I don't no for sure
My Frankenmill has an M head. The fine feed doesn't work on it either. I have found that there is leathers or some-such in the fine feed that dry or wear out and it will not work. I haven't taken the time to look into it on my machine. I just use the side lever. it works for everything I do.

Do you have to do anything to engage the wheel? This is my first mill I haven't been around them either. I'd just like to make sure I have a problem before I tear into it
