Adjusting the Bobbin Tension
Posted: 28 August 2009 at 3:30 p.m.
Some have asked us: "Is it ever necessary to adjust the bobbin tension?

The answer: Sometimes. Some bobbin cases work themselves tighter over time. If the bobbin thread is breaking, chances are the tension may be too tight. Before making adjustments, put a dot with a permanent at the top of the screw alignment so you can always go back to that setting. Then, loosen the tension screw 1/4 turn. Remember "righty-tighty and lefty-loosey."
A fine, smooth thread may require a tighter tension setting to prevent spooling off or backlash and a heavier decorative bobbin thread may require a looser tension to allow the thread to pass through the tensioner.
