How do I adjust tension on a Necchi Lydia 510 sewing machine?
New thread, re-stringing both the upper thread and bobbin thread. Tried to "tweek" machine by turning adjustment knobs trying to achieve a good tention but the either breaks during stitching or produces loops of loose thread on underside from bobbin case.

Loops under fabric means top tension needs to be tightened
try cleaning the top tension dial with some unwaxed dental floss and see if that helps. if it doesn't then the tension dial may need to be replaced
also check to make sure the spool of thread is not getting caught on the spool holder
also try a new needle--one that is correct for the fabric being sewed
