Properly threading a Consew 206RB-series industrial walking-foot sewing machine, specifically the 206RB-2.
UPDATE!!! I was wrong about the thread going over the top and down the right side of the PIN of the thread tensioner disks. I have since learned from a much clearer manual that the thread DOES NOT go over this pin. It goes from the tension disks straight down to the thread controller. I will try to annotate the video accordingly.
