This message is displayed when the motor locks due to tangled thread or for other reasons related to thread delivery.

• If the fabric is caught in the machine, remove the fabric from the machine.
• Check the condition of the upper thread. If the upper thread is tangled, remove the thread tangled in the machine.
• Check the condition of the bobbin thread. If the bobbin thread is tangled, remove the thread jammed and clean the race.
• Check the condition of the needle. If the needle is broken, bent or blunt, replace the needle with a new one.

Before continuing sewing:

• Turn the handwheel toward you (counterclockwise) to check if the handwheel moves smoothly.
• Be sure to thread the machine properly. Improper threading can cause  problems again.
• Make sure that you have chosen a thread and needle that are appropriate for the fabric that you wish to sew.
  Incorrect combinations of fabric, thread, and needle can cause sewing problems.
  Refer to the fabric/thread/needle combination table for details.
