Frequent question: How do you adjust the bobbin tension on a Husqvarna?

Do I need to adjust bobbin tension?

The bobbin tension can become looser even if you haven’t changed the setting yourself. Sometimes it’s still necessary to loosen or tighten the bobbin tension. You can change the front loading bobbin tension easily. But with drop-in bobbins – it’s not so easy.

Why does my Husqvarna sewing machine keep jamming?

Lack of tension on the upper thread

However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.

What happens if bobbin tension is too loose?

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.

Why does my bottom thread keep bunching?

If the thread has knots, is not smooth, is uneven, or is loose on the bobbin, then it has not been threaded correctly. If your machine uses a bobbin case, follow your sewing machine’s instructions to remove the bobbin from the case and re-thread it.

Changing Bobbin Tension

You should see a small screw on the flat/closed side of the bobbin case. Turning the screw a tiny bit counterclockwise will loosen the bobbin tension; turning it clockwise will tighten the tension.
