There could be several reasons why the needle keeps breaking.

1. Make sure the needle is correctly inserted with the flat side facing the back and pushed up into the machine as far as possible.
2. The needle could have been damaged or bent. If so replace with a new one.
3. The upper thread could be installed incorrectly. Rethread the machine according to the instructions in the manual.
4. The upper thread tension could be set too tight. Set the tension to the best thread tension setting or less.
5. The thread density of the embroidery data is too fine. Three or more overlapping stitches are being sewn. Using a data design system, correct the thread density and overstitching settings in the embroidery data.
6. A bobbin designed specifically for this machine is not used. Be sure to use the correct bobbin.
7. The needle is incorrect. Be sure to use the embroidery needle.
8. In the cases shown below, consult nearest authorized Dealer or Service Center.

• The area around the hole in the needle plate is damaged.
