Question about Bernina Sewing Machines

1 Answer

I cannot get a perfect stitch on my Bernina 1260. Some of the bobbin thread shows on top no matter what I try. I have tried different needles, threads, tension settings (even adjusting bobbin tension). It is especially unsightly when I try to free-motion quilt. Also, I am frequently hearing a slight clunking type noise (even with a new needle). Thanks for any help! Sandy Smith

Possibly its the check spring that takes up the slack in the thread as the needle pierces the fabric. slowly lower the needle through the fabric and watch if there is slack in the thread just above the fabric. If there is then this check spring needs to be adjusted. I hate to say this and its not just because I am a Bernina tech but its time for it to be serviced. many things might be the culprit. The distance between the hook and needle could be off for one more reason. Or something dirty or fluff under the spring the thread goes under on the bobbincase. Either a servicing or use the same color bobbin thread beneith is in order. Wish I could help more but you have tried a lot so I ruled those out such as tighter bobbin tension or looser upper tension or the combination of both.
Good luck

I have a Bernina 145 S activa and I can't get my satin stitch to work , it brings the bobbin thread to the top , what can I do ?


Do you use stabilizer when you are satin stitching? I had a teacher who also hooped the fabric with a spring-loaded embroidery hoop (turned upside-down under the presser foot so the fabric is flat against the needle plate) that would keep the fabric taut.

It is not uncommon for bobbin thread to rise to the top when doing embroidery, satin stitch, etc., especially if you are using lighter-weight thread than usual. You would normally loosen the upper tension so the upper thread will sink into the fabric. However, if loosened upper tension is not doing enough, you may need to adjust bobbin tension when doing embroidery, applique... You might try tightening the bobbin tension just a smidgen to get the bobbin thread to stay below the fabric. Be sure to mark the bobbin case before making any adjustments so you can return it to the original setting when finished with the satin stitch. (If you do a lot of satin stitch or applique, etc., you may want to invest in a separate bobbin case that is set up only for doing that kind of work--saves having to alter the bobbin tension frequently.)

How do I thread the 960 Bernina Bobbin?


I'm assuming you have a front loading bobbin. Look at your bobbin. Hold it so the thread is falling down from the top to the right side. Slip it straight in to your bobbin case, and pull up through the slit, until it snaps in through the side clip.
Generally, if you are missing stitches, the hook isn't picking up the thread from the needle, and you will need to take it in for service at a Bernina dealer.

12 wt thread


12 wt thread generally will not work well in the bobbin...


"Aurifil 12wt Thread
Aurifil 12 wt thread is ideal for hand quilting, big stitch hand quilting and machine quilting. 12 weight thread creates a more defined and often primitive look. It's great for designs that use a longer stitch length if using a machine. When machine quilting with 12 wt thread, use 40 wt in the bobbin, increase your stitch length, lower your tension, use Topstitch size 90 needles and stitch slowly."

I need to find out how to set up my machine for polyester/spandex material.


For spandex you will probably want to use a size 70 needle for stretch fabric. You should be able to leave your tension settings on standard tension but may need to go for a slightly shorter stitch length.
try stitch length of 2.5 or 3
tension of 3.5
check your bobbin tension, to do this thread the bobbin and suspend it in the air holding the thread. If the bobbin falls to the floor the tension is too loose. If the bobbin hangs in the air and you give a gentle tug on the string the bobbin should slide along the thread an inch or so. If it doesn't budge it's too tight.

When you say the thread is not the same on top as the bottom do you mean you are using different threads or that the stitches are coming out different on the top to the bottom of the fabric?

Thread tension will not adjust.


Check your setting, you have your stitches set too far apart. Wherever on your machine you see the zigzag stich you will see other stich settings, look at it until you see the right amount of stiches you want.

Bernina activa 210 won't zigzag and has bobbin issues on straight stitch


it's very possible that the machine is slightly out of time & needs to be service at a sewing machine shop
is the fabric & thread & needle compatable with each other?
did you use every thread guide when threading the machine?
is the bobbin in correctly?
is the bobbin warped?

I have a Bernina 530 Record and i'm trying to but


You would be best to download an instruction manual for your machine as it explains clearly, with diagrams how to thread and insert the bobbin. You probably wont find the 530 manual however download a copy for Bernina 530-2 or 532-2 as they are almost identical to the 530.

Bernina 180 thread breaking and tension problems


First make sure that you are using a new needle in the proper size. A needle with burrs on it will cause the bird's nest problem. Also, is the thread you are using old? My repair guy told me to keep my filled bobbins in the freezer to maintain their humidity, and that has made a world of difference in my stitching. Finally, how long has it been since you had the machine cleaned and serviced, and was it by an authorized Bernina repair shop? Bernina machines have special screws that only Bernina authorized repair people have - I discovered that when I took my machine in to someone who was not authorized only to have the timing go off in a matter of weeks. The authorized repair guy found clumps of thread that had been air blasted into the inner works of the machine and those clumps were getting caught up in the new stitching and causing the same problems you described. Good luck!

The needle thread will not pick up the bobbin thread


It looks right but its not. Try looking on the internet for threading instructions. The bobbin winds in two directions, I have never saw a Bernina but I have 2 new machines and the thread goes in and then threads back to the left. Its hard to describe. But if the bobbin isn't right it will not pick up the thread. Write to Bernina for instructions. There are websites that have the directions for free.
