Things You'll Need
Instructions
Move the needle as high as possible and lift up the front of the metal bobbin plate to remove it.
Remove the old bobbin from the bobbin holder by pulling up on the small lever visible in the case. Lift the bobbin out of the case.
Insert the new bobbin into the case, making sure it will turn to the right when the thread is pulled.
Pull the end of the thread through the hole on the side of the bobbin case, then under the spring clip to the left of the hole. Feed the thread through the slot on the far right of the bobbin plate and replace the plate.
Test the bobbin on a scrap piece of fabric and troubleshoot any problems that might occur.
