9. Attach zigzag foot "J".

    

   When using the twin needle, be sure to attach zigzag foot "J".

   If bunched stitches occur, use presser foot "N" or attach stabilizer material.

    

10. Turn on the sewing machine and select a stitch.

     

    When using the pintuck foot (sold separately) to sew straight pintucks with the twin needle, select the stitch with the center needle position.

     
    • When using the twin needle, be sure to select an appropriate stitch, otherwise the needle may break or the machine may be damaged.
       
    • After adjusting the stitch width, slowly turn the handwheel toward you (counterclockwise) and check that the needle does not touch the presser foot.
      If the needle hits the presser foot, the needle may bend or break.
     

11. Start sewing.

    Two lines of stitching are sewn parallel to each other.

    

     

    • When changing the sewing direction, press ("Needle Position" button) to raise the needle from the fabric, and then raise the presser foot lever and turn the fabric.
      Otherwise the needle may break or the machine may be damaged.
    • Do not try turning the fabric with the twin needle left down in the fabric, otherwise the needle may break or the machine may be damaged.
    • Only use the twin needle.
      Use of any other needle may bend the needle or damage the machine.
    • Never use bent needles.
      Bent needles can easily break, possibly resulting in injuries.
