Upper Thread Breaking
Possible cause:
Thread path obstructed
Solution:
Check if thread is caught on thread spool (rough spots on the spool itself) or behind spool pin or spool
cap (if the thread has fallen behind the spool cap and therefore cannot feed freely through the machine
path).

Machine is not threaded correctly.
Solution:
Remove upper thread completely, raise presser foot lifter, rethread machine making sure thread is in take-
up lever (raise take up lever to its highest position by turning hand wheel toward you.
Possible cause:
Upper tension too tight.
Solution:
Reduce upper thread tension (page 16).
