Winding the Bobbin

Using the Supplemental Spool Pin

While the main spool pin is being used for sewing, you can wind a bobbin by 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. Groove in the bobbin
   2. Spring on the shaft

3. Place the spool of thread for the bobbin and the spool cap onto the supplemental spool pin.

   
   1. The thread unwinds to the front from the bottom.
   2. Spool cap
      IMPORTANT

      • If the spool or the spool cap is not installed correctly, the thread may become tangled around the spool pin and the machine may be damaged.
      • Choose a spool cap that best fits the size of spool being used. For more information regarding the choice of spool caps for your thread choice, refer to How to Use the Spool Cap and Spool Net.
        
        

4. 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. Thread guide

5. Pass the thread around the pretension disk making sure that the thread is under the pretension disk.

   
   1. Pretension disk
   2. Check to make sure thread is securely set between pretension disks.

6. Wind the thread clockwise around the bobbin 5 or 6 times, pass the thread through the guide slit in the bobbin winder seat, and then pull the thread to cut it.

   
   1. Guide slit in bobbin winder seat
      (with built-in cutter)
      • Be sure to wind the thread clockwise around the bobbin, otherwise the thread may become wrapped around the bobbin winder shaft.
      CAUTION

      • Be sure to cut the thread as described. If the bobbin is wound without cutting the thread using the cutter built into the guide slit in the bobbin winder seat, the thread may become tangled in the bobbin or the needle may break and cause injury when the bobbin thread starts to run out.

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

   
   1. Bobbin winding switch
      • Use the bobbin winding slider to adjust the amount of thread wound onto the bobbin to one of five levels.
        
        1. Bobbin winding slider
        2. More
        3. Less

8. Touch [Start].

   If the bobbin thread is wound incorrectly, touch [Stop]. Cut the thread, slide the bobbin winding switch to the right, and then remove the bobbin.

   
   1. Touch to decrease the winding speed.
   2. Touch to increase the winding speed.
   • Bobbin winding starts. [Start] changes to [Stop] while the bobbin is winding. The bobbin stops rotating when bobbin winding is completed. The bobbin winding switch will automatically return to its original position.
     • Touch [OK] to minimize the bobbin winding window. Touch (in top right of the LCD screen) to display the bobbin winding window again.
       
     • 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.
     IMPORTANT

     • For stretchable thread such as transparent nylon thread, start winding the bobbin at low speed, then stop when it is about half full. Otherwise, the bobbin may not be wound neatly or may be damaged.

9. After bobbin winding is finished, cut the thread and remove the bobbin.

   
   IMPORTANT

   • 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.

Using the Spool Pin

You can use the main spool pin to wind the bobbin before sewing. You cannot use this spool pin to wind the bobbin while sewing.

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. Groove in the bobbin
   2. Spring on the shaft

3. Pivot the spool pin so that it angles upward. Set the thread spool on the spool pin so that the thread unwinds from the front of the spool.

   
   1. Spool pin
   2. Spool cap
   3. Thread spool
   4. Spool felt

4. Push the spool cap onto the spool pin as far as possible, then return the spool pin to its original position.

5. While holding the thread with both hands, pull the thread up from under the thread guide plate.

   
   1. Thread guide plate

6. Pass the thread through the thread guide.

   
   1. Thread guide

7. Pass the thread around the pretension disk making sure that the thread is under the pretension disk.

   
   1. Pretension disk
   2. Check to make sure thread is securely set between pretension disks.

8. Follow steps 6 through 9 of Using the Supplemental Spool Pin.

Using the Spool Stand (Winding the Bobbin)

Pass the thread from the spool through the thread guide on the telescopic thread guide, and then wind the bobbin according to steps 4 through 9 of Using the Supplemental Spool Pin.
