Hello there,
Theres a number of causes of such problems. You will simply just have to run a check on some of the components below:
If it is the upper thread that is breaking, check Rethread your machine. An incorrectly threaded machine can cause thread to break.
Decrease the tension on your machine. The tension may be too tight for your thread.
Reposition the spool of thread on the spindle. You know that little nick in the edge of a spool that's used to hold the loose end of the thread? Your thread may be catching on this nick as you sew. Place your spool so that this nick rests against the bottom of the spindle.

Reinsert your needle. Make sure it goes all the way into the holder and that it's positioned correctly, usually with the flat side away from the bobbin, but consult your machine's manual to be sure.

Change your needle. Your needle may be bent or dull. The eye of your needle may have a nick in it that's cutting the thread as you sew. Or the eye of your needle may be too small for your thread, in which case, change to a larger needle. And make sure your needle is appropriate for the weight and type of your fabric.

Change your thread. Your thread may be weak. Or your thread may be fuzzy and irregular, causing it to catch in the eye of your needle as you sew. Cheap thread tends to be weak and fuzzy, so make sure to use a quality, brand name thread. And if you've been sewing with an older cotton thread, which can dry out and become brittle with age, try a newer thread.
Check your presser foot for damage to the needle hole.A burr in your presser foot's needle hole may be cutting your thread. Gently smooth any rough spot you find with an emery cloth.
Also, There may be a burr in one of your thread guides, in which case, you may need to have your machine professionally serviced to have the part replaced.
If your lower thread is breaking: Reinsert your bobbin. Your bobbin may not be seated properly in its case.
Rethread your bobbin. Your bobbin may be threaded incorrectly or the thread may be tangled.
Remove some of the thread from your bobbin. If your bobbin is very full (if it's hard to insert into the case, it's too full), this may be keeping your bobbin from turning smoothly.
Rewind your bobbin thread. If your bobbin thread is wound unevenly, this may be keeping your bobbin from turning smoothly.
Try a new bobbin. There could be a nick along the edge of your bobbin spool that's catching your thread as you sew.
Clean the lint from your bobbin case.Lint in your bobbin case could be keeping your bobbin from working properly.
Check the needle hole in your throat plate for rough spots. A burr in the needle hole of your throat plate (usually caused by the needle hitting the throat plate) could be cutting your thread. Gently smooth any rough spot you find with an emery cloth.
Hope this helped. Goodluck Elect_Comp

What is the difference between a sewing machine and a serger?


Well..... A serger (or overlock) sews a different, and usually more complex stitch. Where a sewing machine usually only uses two threads to make the stitch, a serger can use two, three, four or even five threads and will sew around the edges of the work piece, as well as trimming the edge of the work just ahead of the sewing area, or as you feed the work in, the trimming takes place first. Sergers also make a stronger seam, attributable to more thread / stitching in the seam. Sergers are versatile and quick, but one drawback is the fact that sergers make a chain stitch instead of a lock stitch, like a machine with a bobbin, and lock stitches can be pulled out, like the stitching that used to close dog food bags and bags of charcoal. A lock stitch is just what it sounds like, it can't be pulled out. You only get a lock stitch with a machine that uses a bobbin, and sergers don't use bobbins. That fact makes serging desirable for the speed of production. Changing bobbins takes up a lot of time, even if you are using pre-wounds. Hope this helps!

My overlocker is jammed with the needles in the down position - I have not used it for a while and hve just oiled and cleaned it.


Oh man.

Not sure how to get it unjammed but I know that if overlockers/sergers aren't threaded properly they can jam up like that. The last time that happened to me... broken looper.

Open up the front and start clipping threads... Gently rock the hand wheel to see if it loosens as you get thread released.

Honestly I suspect that your machine has locked up because it's been knocked out of time. If you still have problems take it in and have it serviced.

I can't understand how to thread lower looper (red) The instructions on the cover are very unclear


Sounds like you are trying to thread a serger or overlock. I would be helpful if you offered up the model number. However, a few things I've learned.

Sergers MUST be threaded in ORDER. Failure to do so will break your looper (had it happen)

In other words if you break one of the 4 or 5 threads... you have to un-thread all the other points and begin with Thread 1, then do thread 2, etc., etc.,

If you would give me the Make and model number of your serger... I will be happy to see if I can find your manual and threading guide for you.
