Hello Anne,
Nice machine that one, make sure that when you thread the machine the presser foot is up so the thread goes between the tensions discs, top tension between 4 and 6, bottom tension should be enough to pull the thread through with some resistence, if it is too loose tighten the screw on the bobbin case clockwise about a quarter of a turn, any problems let me know.
