EMC 10 TRIMMER SYSTEM NOT TRIMMING THREAD

TRIMMER SYSTEM NOT TRIMMING THREAD (TOP OR BOBBIN):

  1. Check the Technical Manual to determine what part of the Trimmer System is causing the error. (Trimmer Option Section)
  2. Inadequate or too tight Thread Tensions can cause the trimmer system not to cut thread correctly. If the thread tension is too loose, the trimmer blades won't select the thread to be cut or miss it. It may also cause frayed cuts.
  3. If the Thread Tension at the main black knob tensioners or on the Bobbin Case is too tight, it will cause the thread to pop out of the needle or bobbin to pop back so that it is too short to be picked when the machine resumes sewing after a trim. This will register as a THREAD BREAK.
  4. Select Timing may be off. check the Technical Manual to see how this is done. It is suggested that a trained technician perform this operation. (Trimmer Option Section)
  5. Call your distributor if the machine still either won't trim consistently or at all.
