Tension I am having the same problem as listed for this machine. I made the mistake of taking the tension adjustment disc off and am not sure if I have itt back on correctly. Does anyone have a diagram or a correct listing of the way the parts are to go back on the tension adjuster?????? I am getting lots of loops on the bottom and lots of thread breakage from the needle.

Hi, Your problem is the UPPER tension. The thread may not be getting between the tension discs. Try this: Make sure the presser foot is up and thread the machine stopping short of the eye of the needle. Pull on the thread and it should move easily, Now drop the presser foot and you should feel tension on the thread. Adjust the tension up and down and you should feel a difference.
If there is no change then there is something keeping the tension discs open.

Test top thread tension. Remove top thread, set tension selector to 4, presser foot up, and needle up. Thread machine up to needle eye. Threading needle eye won't be necessary.


Now make a long slow steady pull of top thread. Thread should advance smoothly without snagging or sudden change of tension. Next lower the presser foot and repeat with long slow steady pull of top thread. Again thread should advance smoothly without sudden change in tension. Note the difference of no tension when foot up and selected tension 4 with foot down.


If you find there is no difference between foot up (no tension) and foot down (selected tension) then tension disc are not working or thread is not between tension discs.

When your bottom thread is messy it is the top thread needing adjustment. Your machine may not be threaded properly and the thread may not be sitting correctly between the tension discs.
Check to make sure your machine is threaded correctly.
Check thread between the tension discs.
After checking, adjust the tension (tighter) and do a test. If it is still messy add some more tension and do another test.

Hi, The tension is a factory setting that should not be normally adjusted. the lower tension should be fairly stable.
if you happen to have the "bird nesting " happening on the bottom of your project that is caused by the top tension being too low or bypassed by mistake, or the take up hook not threaded on the top. If you wan t to email me directly at [email protected] i would be happy to try to help.

1. Adjust the bobbin tension tighter. The tension you are trying for is to be equal to the top tension.
2. The top tension should start at about four. When you are threading the top do it with the pressure foot up.
3. As you are threading the top give little tugs to check for snags.
4. When you thread the tension control make sure it goes through the tension disc.
5. After you have threaded (except needle) lower the pressure foot.
6. Give a tug to see if the thread will move without excessive resistance.
7. Thread the needle and try sewing.

Before you go adjusting tensions, make sure your upper thread is threaded properly. Always thread with the presser foot in the UP position so the thread can slip easily between the tension discs. Also make sure there are no wraps around the thread spool spindle.

Be certain that you have the bobbin properly inserted as well.

Once you are absolutely certain that there is no issues is threading. The tension is adjusted by a wheel on the top of the machine. Left to loosen, right to tighten the tension.

Possible problems are lint between the tension discs. You can clean this with a business card. If the tension discs are not meeting together you must take the machine apart to adjust the spring tension. If all the tension discs not closing. If that is the case your presser foot tension release lever may be stuck.

thread loops on the bottom is a sign that it isn't threaded correctly or the tension isn't set right.

Industrial machines tend to do some strange threading procedures. Are you sure you have it threaded correctly? Two of the machines I've had required that I do a 360 around one of the tension discs. I would start there.

Also some industrial sewing thread is waxed and that wax can cause you issues in between the tension discs. Raise the presser foot and take a piece of sturdy material like canvas or denim and "floss" between those discs. It will help remove wax build up that could be keeping your tension discs from working properly.

U do not recomend that you adjust the bobin tension, what do you have the top tension set at? It should be between 3 and 4, have you put in a new needle? Also, check to make sure the thread is 'seated' right between the tension disc, if you stil have a problem then your machine is out of time.

There is probably a thread broken off inside the tension discs.To remove it ,adjust the tension knob to 0 tension, and raise the presser foot. Spread the tension discs a part with a small screwdriver and blow some canned or compressed air through the discs.You should see some thread or lint come out of it.

Rethread the machine,adjust the tension back to 5 and test the tension by pulling on the thread near the take up lever. When the foot is up there should be almost no tension. When the foot is down you should have tension.
