How do I wind the bobbin?

The included bobbin was designed specifically for this sewing machine. If bobbins from other models are used, the machine will not operate correctly.

Use only the included bobbin or bobbins of the same type (part code: SA156, (SFB: XA5539-051)).

Using the Supplemental Spool Pin

 

Winding the Bobbin Using the Spool Pin

 

 

Using the Supplemental Spool Pin

 

With this machine, you can wind the bobbin without unthreading the machine. While using the main spool pin to sew, you can conveniently wind the bobbin using the supplemental spool pin.

 


     (1) Supplemental spool pin

  1. Turn the main power to ON and open the top cover.
     
  2. Align the groove in the bobbin with the spring on the bobbin winder shaft, and set the bobbin on the shaft.

  1. Set the supplemental spool pin in the "up" position.

  1. Place the spool of thread on the supplemental spool pin, so that thread unrolls from the front. Push the spool cap onto the spool pin as far as possible to secure the thread spool.

  • If the thread spool and/or spool cap are set incorrectly, the thread may tangle on the spool pin and cause the needle to break.
     
  • Use the spool cap (large, medium, or small) that is closest in size to the thread spool. If a spool cap smaller than the thread spool is used, the thread may become caught in the slit on the end of the spool and cause the needle to break.

 

  • When sewing with fine, cross-wound thread, use the small spool cap, and leave a small space between the cap and the thread spool.

  • If a spool of thread whose core is 12 mm (1/2 inch) in diameter and 75 mm (3 inches) high is inserted onto the spool pin, use the special spool cap.

    * Depending on the model you purchased, the special spool cap may be included with your machine.

 
  1. With your right hand, hold the thread near the thread spool. With your left hand, hold the end of the thread, and use both hands to pass the thread through the thread guide.

  1. Pass the thread around the pre-tension disk making sure that the thread is under the pre-tension disk.

Check to make sure thread is securely set between pre-tension disks.
 

  1. Wind the thread clockwise around the bobbin 5-6 times.

  1. Pass the end of the thread through the guide slit in the bobbin winder seat, and pull the thread to the right to cut the thread with the cutter.

Be sure to follow the process described. If the thread is not cut with the cutter, and the bobbin is wound, when the thread runs low it may tangle around the bobbin and cause the needle to break.

 
  1. Set the bobbin winding switch to the left, until it clicks into place.

  • Sliding the bobbin winding switch to the left switches the machine into bobbin winding mode.
  • The bobbin winding window appears.
  1. Press START.

  • Bobbin winding starts automatically. The bobbin stops rotating when bobbin winding is completed. The bobbin winding switch will automatically return to its original position.
  • " START " changes to " STOP " while the bobbin is winding.
  • Stay near the machine while winding the bobbin to make sure the bobbin thread is being wound correctly. If the bobbin thread
    is wound incorrectly, press " STOP " immediately to stop the bobbin winding.
  • The sound of winding the bobbin with stiff thread, such as nylon thread for quilting, may be different from the one produced
    when winding normal thread; however, this is not a sign of a malfunction.
 
  • You can change the winding speed by pressing " - " (to decrease) or " + " (to increase) in the bobbin winding window.

    image
  • Press " CLOSE " to minimize the bobbin winding window. Then, you can perform other operations, such as selecting a stitch or adjusting the thread tension, while the bobbin is being wound.
  • Press image　(in top right of the LCD screen) to display the bobbin winding window again. 
 
 

 

  1. Cut the thread with scissors and remove the bobbin.

    image

 

  • When removing the bobbin, do not pull on the bobbin winder seat. Doing so could loosen or remove the bobbin winder seat, and could result in damage to the machine.
  • Setting the bobbin improperly may cause the thread tension to loosen, breaking the needle and possibly resulting in injury.
