Leave 3 to 4 inches of thread projecting from the bobbin.
4. Place bobbin on the bobbin winder spindle and push spindle towards bobbin winder stop, to engage the bobbin winder mechanism.
5. Hold end of thread and operate foot control to start the machine.

Correct thread tension
When upper and bobbin thread tension is correct, thread will be locked in center of the seam.
If upper thread tension is too tight or bobbin thread too loose, loop will be at top of fabric.
You will need to decrease the upper thread tension.
If upper thread tension is too loose or bobbin thread is too tight, thread loop will be on bottom of fabric.
Increase the upper thread tension to correct this.

thread tension it may be necessary to make a slight adjustment on the
bobbin tension.
