It's actually very simple. You can ignore most of the computer stuff (I rarely use it) and even though I have over 100 machines, I consider this to be one of the easiest to thread. Thread goes on the back, to the back loop then across to the front in the tension slot, loops over the big hook and through the uptake arm, then down the front to the needle. Needle threads front to back and if you put the foot down, the white spot on the foot shows through the eye and makes threading very, very easy.
