Try this link for a free manual, check the information on adjusting
the top tension and see if it will help you, if it doesn't then the machine
may need to be checked to see if there is something wrong with the
top tension dial

    My machine is new, I bought at the beggin of the year. First time I sew was a week ago. Then I changed the thread and the tenion would not grab so I took it to a shop and he said the top tenion was missed up and that it would cost more to repair it then what I paid for it . So I though I would try myself before I bought a new machine

    He dose not care for singers and perfers not to work on them.

  • try taking a can of air that you use on a computer and use it on the tension dial, or try unwaxed dental floss and go between the discs if that is possible,,some thread can leave alot of lint try the air or dental floss and see if that will help. I suggest using a good name brand thread, some machines can't handle cheap thread. if the air or dental floss doesn't work and you have to get a new sewing macine try looking at a sewing machine shop and not the one the repair man work at, because singers are a good machine and he's just not the knid of repair man I'd take a machine too. again try changing the thread to a better brand,,,try rethreading the machine top and bobbin and make sure to use every thread guide this is very important for the machine to operate right and make sure the bobbin is turned correctly in the bobbin case, and if it a front or side loading bobbin with a case you have to take out make sure the bobbin case is correctly put back in the machine.

Loose bobbin tension

the bobbin tension is set by that small spring plate that you pull the thread under after you put the bobbin back in the carrier / holder
a very small turn of that screw makes a big difference ob the tension unlike the needle thread tension
mostly the problem ( you never bothered to mention the symptom ) is bird nesting under the fabric which is the needle thread tension not tight enough

I have a Necchi 1537 and my tenion is off and don't know how to fix it...Can you help me?

When you say it is off I hope ypou mean it is not adjusted properly, top tension about 4 or 5, you should be able to just pull the bottom thread through with the slightest resistence, if it is too tight just slacken the screw on the bobbin case anti clockwise about a quarter of a turn and test and repeat if necessary.

I am trying to free-motion quilt using my Bernina 1530. Everything is fine until I quilt a curve or a circle. Then the thread on the back is too loose. I have tried adjusting the top tension, as well as...

I don't have the BSR (Bernina Stitch Regulator) and presume you don't either. I have found that I tend to move the fabric to quickly when sewing curves and circles. I did as you did and changed tension, stitch length...everything, but nothing worked. I finally found that the best solution was to SLOW DOWN on the curves. No problem ever since. I hope this helps you. If it does, please let Fixya know by rating my solution!

I need my sewing machine adjusted. Tenions are

You can call different fabric shops to see if they have a repairman that does house calls.

The machine may need a total tune-up and this requires shop time.

In the mean time - set the top tension at 4 and then thread the machine with the presser foot up.

For the bobbin, use a contrasting thread for this test.

If this is a rotary (vertical with metal bobbin case), insert the bobbin into the case so the thread is feeding clockwise and through the guides on the side and of the case.

Take hold of the bobbin thread tail and if it falls like a yo-you, you need to tighten the screw on the side of the bobbin case so the bobbin thread does not pull out while being held in said position.

Make tiny adjustments to the right.

If the bobbin thread is so tight that the top thread is pulling to the underside, loosen the screw ....tiny increments to the left.

Once you have the bobbin tension set, do a test stitch and the top and bottom stitches should be balanced.

Too much bobbin thread on top, loosen the top tension - lower number.

Too much top thread on the bottom, tighten the top tension - higher number.

Singer futura ce-200 tension problem

stop, remove all threading, clean machine,be sure to clean the top tenion disks with a thicker thread, change needle, rethread carefully and try a test swatch. If not working still, your tension could be out of adjustment. Adjust top tension until the top thread of your swatch balances with the bottom. Use two contrasting colors of thread so you can know which tension is wrong,
Remove bobbin and dangle by the thread, it should not move untill you jerk it and should drop about 3-4 inches. Adjust small screw until this works. Try another swatch.
