You first run it through the catch at the top, then loop it to the right of the tension dial under and then back up to the top of lever thingy, I don't know what its called, back down to the needle, threw the holder thats near the needle screw, and then threw the needle. I hope that helps.
First off, pretty sure that number you listed is the serial number, second their is a diagram right on the front panel. Unless whoever owned it before you did not put on the freaking sticker it is right there, outlined in red on a black diagram. Oh lord
