Necchi supernova manual

There is a lever for positioning the needle bar. When you move the lever to the left middle or right , the needle bar too should follow the same. Try to do that. If it doesn't follow the lever and stays at one end, that means the machine needs to be oiled. Not like most sewing machines Supernova swings the bottom rod too to left and right when Zig Zag is engaged. I recommend to spray some WD 40 first, to inside of top and bottom side of the machine , and later to apply machine oil to every moving joints.

Just measure the existing belt and go from there. Besides the supernova and supernova ultra are likely to use the same belt.

try rethreading, make sure the foot is up, change the needle, make sure there are no loose threads or lints under bobbin case. You might also try rewnding the bobbin to make sure it is wound evenly.
