I couldn't find a picture of your machine, but the bar closest to my belly is the bar that I load the back on. The top can be loaded on the next bar, but I do float most of mine. The other end of the backing fabric should be loaded on the take up roller. I have leaders and pin, but they are coming out with several new methods all of the time.
These are for HQ machines, but the one on loading a quilt is really good.

Good luck!
