Connect the machine to the power supply and turn on the main power.
Place the spool of thread on the spool pin.
The thread end should come from the bottom front of the spool.
The spool cap closest to the thread spool size should be used to hold the spool securely on the spool pin.
Pass the thread through the thread guide as shown by the arrows.
Align the groove in the bobbin with the spring on the shaft and place the bobbin on the bobbin winder shaft.
Then, push the bobbin winder shaft to the right.
Wind the thread clockwise around the bobbin four or five times, pass the end of the thread through the slit in the bobbin winder seat, and then pull the thread in the direction shown in the illustration.
Use the cutter to cut the thread.
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.
Slide the sewing speed controller to its maximum (as far to the right as possible).
Press the "START/STOP" button.
The bobbin will stop winding when it is full.
After the bobbin has stopped moving, press the "START/STOP" button to stop the machine.
Cut the thread, slide the bobbin winder shaft to the left and remove the bobbin.
Immediately after winding the bobbin, it is normal to hear the sound of the clutch engaging when beginning to sew or manually turning the balance wheel.
