I have an Usha Janome sewing machine. The thread gets cut in a few stiches. Is it a problem with tension?
The tension may be too tight, the needle may be threaded incorrectly, the thread may be old or poor quality, or the needle may need to be changed.
I would start with trying a different spool of thread. If not that, then just the tension.
make sure your thread is not getting caught on the spool
Here is some info from a Janome web site:
Why does the thread keep breaking?
The easiest first step to correct thread breakage is to snip your thread at the spool and rethread.
If you have different sizes of spool caps, are you using the correct size? Threads can tangle around the spool pin and snap. The spool cap helps to prevent this.
Upper thread tension could also be too tight. Try lowering the tension (lower the number).
Are there any burrs or rough spots in the needle plate from a previous needle breaking mishap? Such burrs can cause fabric snares and thread breaks. Burrs can be smoothed with an emery board or fine sand paper.
The same results can happen from a burr or other damage in the bobbin hook.
Double check that the needle size is up to the job at hand. A fine needle cannot effectively stitch denim, for example.
How is the quality of the thread being used? All threads are not created equal. Threads with excessive slubs or knots will grab and break. Inconsistent threads will have weak spots that break, as will loosely twisted threads. Use good quality thread. Your machine will not get fuzzed up and your project wont fall apart!

Sometimes it can be difficult to find replacement parts for an older machine, especially if you bought it used and don't have a manual. Your local repair shop might be able to help. This is a page about finding replacement parts for a Janome sewing machine.
The stitch length on a sewing machine sometimes needs to be readjusted. If the controls do not work correctly, it may be time to take it in to the repair shop.
