Troubleshooting
7 . BOBBIN WINDING DIFFICULTIES
Possible Cause: Bobbin thread loosely wound on bobbin
Solution: Rewind bobbin, making sure that the thread is placed snuggly in the bobbin winding
tension disk. (See Page 12)
Possible Cause: Bobbin winding spindle not fully engaged, therefore bobbin not winding
Solution: Check that the bobbin winding spindle has been fully engaged before starting to wind.
(See Page 12)
Possible Cause: Bobbin is winding sloppily because thread end not held at beginning of winding
process.
Solution: Before starting to wind, hold the thread tail (coming out of the bobbin) securely, allow the
bobbin to partially fill, then stop to trim the thread tail close to the bobbin. (See Page 12)
8 . BOBBIN THREAD BREAKING
Possible Cause: Bobbin threaded incorrectly
Solution: Check that bobbin is placed correctly in the bobbin holder. (See Page 13)
Possible Cause: Bobbin wound too full or unevenly

during the bobbin winding process. (See Page 12)
