Baby lock denim pro

I have a baby lock denim pro. the tension spool is jumping the tension. I set it, it sews fine for a very short time then it tightens up binds the thread and it breaks or worse the needle breaks. I want to throw it out in the yard. The thread stands vertical. Its like the tension spring holds for a few seconds then tightens to 10 when it's only on 2. I need this machine to work can you help?

Thank you

What do you set the tention to when you are sewing denim?


Assuming you're referring to Tension.

This depends on fabric thickness, stitch length, and machine capability. Since you did not note your machine type, needle size, thread specifications and material thickness, it is almost impossible to provide a helpful answer.

If you can provide additional information, we should be able to provide an appropriate response.

Best regards,

How do I adjust the timing on my wife's baby lock denim pro (model 1750)?

Raise the presser foot, remove the bobbin case, remove the needle plate. Make certain your correct needle is installed right, with no thread in the needle, rotate the hand wheel until you see the needle at the very bottom of its travel. The hook should be just at the edge of the needle or a fraction from it. As the hook and the needle pass the needle has to start its travel up in order to create a hoop of thread for the hook to catch. If there is not enough travel for a sufficiant hoop to be made the machine may sew but would skip stitches or may not sew at all. If it hits it to late this can cause the hook to split the thread.

WHY??!! *Check if thread is entangled. Check if needle is bent. So far as I can tell everything is fine, used new bobbin, new needle, still getting error. How do I know if the motor has become locked

Time to take it in and have the repair tech service & clean upper tension assembly. When you clip/ change threads be sure not to pull the thread back out of tension assembly. Snip thread at spool, raise foot to release tension and then pull the short thread out from the needle. The Automatic tension is very delicate and pulling thread out backwards can cause thread/lint build up and problems like your having. Sal the Sewing Gal

Hello, I have a Shark euro-pro sewing machine. I am sewing denim on denim using singer needles that were suggested for denim. The numbers on the package are 2020 110/18 808 R 130/705H 05 un I...

The size of needle is fine for sewing on denim so unless the needle is bent (and even so) I doubt that is the problem. Breaking upper thread typically has more to do with the threading, ie wrapped around some place along the way or misthreaded somehow, of even if you somehow got knots or that it has somehow got thread around the spindle for the spool. So first recheck the threading. Best to do by simply totally unthreading it, looking closely at the spool and winding and then rethreading it again. Make sure your upper tension hasn't been accidentally tightened too.

Next check the bobbin and bobbin thread. First pull on the thread. Is it pulling real tightly or does it flow out readily? Take the bobbin out and look at it. Check the tension also. Is it too tight? That too can cause the upper thread to break.

Is the needle penitrating the material smoothly? Again examine the needle closely to see if it's developed a burr. Better yet just swap the needle with a new needle and try it.

The majority of the time it is one of these things that will cause the top thread to break.

I have a Baby Lock pro line and can not get it to sew. I am trying to put in a new bobbin color and it looks fine and feels fine, but when I try to sew it just locks up. Thanks. K

Hi Gypsy:

Take a look at your sewing manual for your Pro Line. I suspect you have your bobbin in upside down. Most machines require the thread to spool off the bobbin in a certain direction.

Tension settings for the babylock sewing machine

I found that the tension setting of 1 worked. The main problem was the machine had thread wound around behind the bobbin. I had to take the plates that are under the foot out, clean out the thread, oil the machine and use a spool of thread that had more weight than the little spool I was trying to use.
