24 TROUBLESHOOTING AND MAINTENANCE Troubleshooting 3. 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). (See Page 14) Possible Cause: 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. (See Page 14) Possible Cause: Upper tension too tight. Solution: Reduce upper thread tension. (See Page 18) 4. THREAD IS SHREDDING Possible Cause: Thread is old or poor quality. Solution: Rethread the top of the machine and bobbin with good quality thread. (See Page 14) Possible Cause: The needle is either worn or old, or it is the wrong style or size for the thread being used. Though it may seem that the machine is shredding the thread, it is usually the needle causing this. If the needle is old or worn out, or if the needle is too small for the thickness of thread, the eye of the needle can cause the thread to shred. Solution: Change to a fresh needle in the correct size for the thickness/weight of thread being used. (See Page 25) 5. THREAD BUNCHING AT BEGINNING Possible Cause: Top and bobbin threads have not been properly placed underneath presser foot before starting to sew.
