Okay, I figured it out. I still don't have power to it, so keep in mind that I can't run it (and haven't run it since we unplugged it at the seller's shop).
It is forward/reverse for the powered feed. I assume you have a lever to do that somewhere on your machine too, just a different spot. I'm reading through your manual (slowly) to try to get the hang of stuff. The forward/reverse is on my on/off switch on the apron.
Do I put the adapter for the MT5/3 in the chuck to hold it immobile? Or does stuff like that just spin and we don't put a load on it?
