No doubt, it is different for sure. I was studying it earlier and I think I have it figured out, other than the threading and the feeding both show that lever "C" is to be engaged. "C" for inch I believe and "V" for metric. Once I see the feed settings and the threading settings, I may have it figured. It's hard to do over the internet though. Now on my lathe, I can have both the leadscrew and feed rod running both at the same time. If the threading lever for the half nut is engaged, the feed lever is locked out and visa versa. Which is what I thought it did, until I pulled the manual out. That's where I found out the one knob on mine disengages the feed rod for threading, but then there is only one lever position which is "P" that disengages my leadscrew. Not bad just finding this out yesterday after having my lathe for almost a year :lmao:
ARM.....I'll be sure to keep an eye out for them.
