How do I change the needle ?

Sewing with a bent needle is extremely dangerous since the needle may break while the machine is being operated. Before using the needle, place the flat side of the needle on a flat surface and check that the distance between the needle and the flat surface is even.

If the distance between the needle and the flat surface is not even, the needle is bent. Do not use a bent needle.

Replace the needle in cases such as the four described below:

  1. If an unusual sound is produced when the needle enters the fabric while sewing trial stitches at low speed. (The tip of the needle may be broken.)
  2. If stitches are skipped. (The needle may be bent.)
  3. After completing one project, such as a piece of clothing.
  4. After using three full bobbins of thread.
  1. Press image (Needle position button) once or twice to raise the needle.

  2. Turn off the machine.

    Before replacing the needle, be sure to turn off the machine, otherwise injuries may occur if the “Start/Stop” button or any other button is pressed and the machine starts operating.

     

  3. Place fabric or paper under the presser foot to cover the hole in the needle plate.

    Before replacing the needle, cover the hole in the needle plate with fabric or paper to prevent the needle from falling into the machine.

     

  4. Lower the presser foot.

  5. Hold the needle with your left hand, and then use a screwdriver to turn the needle clamp screw toward you (counterclockwise) to remove the needle.
    The needle clamp screw can also be loosened or tightened with the disc-shaped screwdriver.
