After threading the machine, start to sew and the thread breaks it seems that it gets caught in step 4 in Threading The Machine in the manual.

Normally incorrect threading, or incorrect tension. First you have to get the bobbin tension correct, and then move to threading and top tension. If bobbin tension is too tight, you are increasing top tension beyond the capabilities of the thread. It may also be that the spool of thread is faulty. What happens if you use button thread?

It is probably not threaded correctly. If you have a book for your machine, look up the threading sequence.

Be sure to thread each in the ORDER specified--for most machines (but yours may differ) upper looper, lower looper, then needles. Follow (closely) the threading diagram on the machine. Missing one guide or hitting the guides out of order will throw you machine into a tizzy! On my serger, the lower looper has to lay over the top of the upper looper/thread before it all gets pulled under the presser foot toward the back of the machine.

It also may help to RAISE the presser foot when threading the machine.

Thread breakage could occur for several reasons.

First, try a brand new needle.

Second, use only good quality thread--NOT old thread or bargain bin varieties.

Third, when threading the upper thread, be sure to ALWAYS RAISE the presser foot throughout the threading process.

Verify that the thread path is correct (consult the owner's manual). Incorrect threading will usually break the thread.

Check that the upper thread tension is set at the midway point between the high & low numbers.

When threading the upper thread, be sure to always raise the presser foot. This releases the tension disk and allows the thread to seat properly.

Thank you and good luck.

Make sure there is no fluff/lint within the bobbin case causing the bobbin to stand proud. Pressure from the bobbin thread can sometimes stretch the bobbin itself.. replace the bobbin with a brand new one. Double check your threading be removing all thread and starting from scratch.

since it's brand new, if it's still under warrenty, take it back & get another one
