I would over ride the auto setting and trial and error the process by manually turning the tension my self, also it has to do with the fabric too, sometimes whatever fabric is being used tends to regulate the tensioner too, good luck

Assicurarsi che l'ago sia correttamente. Assicurarsi che il lato piatto dellago sia rivolto sia anteriore o posteriore, qualunque sia il vostro manuale dice e il modo corretto. Inoltre, essere sicuri che si sia spinto fino nel supporto. Svitare la vite che tiene il piccolo ago, ed estrarre lago in modo da poter essere sicuri che il lato piatto sia rivolto verso la strada giusta. Poi, muovere lago mentre si spinge verso lalto nel supporto e stringere saldamente la vite piccola che tiene l'ago nel supporto. Buona fortuna

I think you have to position the new presser foot under the shank then drop the presser foot lever down as if you were beginning to sew. This should snap the new presser foot right on. Be sure the little bar is positioned under the hook.

Here is a copy of your manual.http://www.singerco.com/uploads/download/498_4205_4210.pdfMost modern machines have snap off and snap on feet. Grasp the foot that is on there and push down. Then while lowering the foot, align the little bar on the zipper foot and watch it snap in. Easy.

Insert a new needle, and make sure that it is inserted all of the way with the flat side facing away from you. If, that doesn't work, it is probably the timing. Then you need to take it for service. Hopefully, it is new and you have a warranty on it, if you have to take it in.

It is not your presser foot, you must mean the feed dogs, they are what moves the fabric along. Clean and Lubricate your machine. Remove the bobbin case and clean it out. Replace your needle now Totally rethread the machine, according to your manual. Test the threading by putting the presser foot up, pull on top thread, it should pull smoothly, now put your presser foot down, the thread should barely move. This will seat the thread in the tension discs. By the way, try your tension on 3. Also, make sure that your presser foot is down before sewing. Always move the handwheel towards you, never away from you because you will mess up the timing. You will see your feed dogs move if you watch.

These are th problems typically caused by:

Improper path for the top thread.
Debris around the bobbin case.
Or a timing problem requiring the machine to be serviced.
