you need to do a tension assembly check.

To do this test. Pull the threadthrough the tension assembly and test it to make sure the tension is workingcorrectly.
(To do this test, adjust your tension setting to normal or medium or 5 orsomething in the middle. Raise the presser foot and pull the thread through thetension. It should pull easily!! Lower the presser foot and pull the thread. Itshould pull noticeably harder.)
If it doesn’t work this way then you probably have a pieceof thread or lint stuck inside the tension discs. To remove it, turn thetension to 0 zero and raise the presser foot.Using a small screwdriver, openthe space between the discs and spray with canned or compressed air. The stuffshould come out. Do the tension test again to make sure you got everything andthen try sewing again.

With your slide plate open, you will see 2 screws on the bobbin case. You need to adjust the one on the inside (not the one that sits at the edge of the metal strip). Do so very slightly. If you can't seem to get it adjusted, take a look and make sure there isn't any thread or lint in between the two pieces of metal that the thread feeds through. This can cause a loose tension.

Hello,

If you have Increased the upper thread tension on your machine, try these solutions.

* Decrease your bobbin tension if your sewing machine allows you to adjust it. Consult your manual.

* Re-thread your bobbin, It may be threaded incorrectly.

* Reinsert your bobbin, It may be inserted incorrectly.

* Change your thread. If your upper thread and bobbin threads are different types, try using the same thread for both.

I hope this helps.

Refer to page 15 of the manual - http://www.singerco.com/accessories/manuals.html

Before changing the tension settings, be sure to thead the machine with the presser foot up as this also has a tremendous effect on the tension and formation of the stitch.
