You will find a box of pre-wound bobbins on the Bobbin Stand itself or on the storage shelf. If there are fewer than 10 bobbins in this box, please let the PoC know so that more may be ordered. Please do not use bobbins that were not purchased pre-wound on the Barudan.


Loading the New Bobbin into the Bobbin Case

Step 1: Hold the bobbin case with the front side down and the opening closest to your body.

Step 4: Bring the thread through the slit in the edge of the bobbin and under the tension spring until it comes out the opening.

Thread passes through the tension spring and then through the hole in the front of the bobbin case.

Step 5: Wind the thread through the metal pigtail on the front of the Bobbin Case.

The pigtail eliminates the need to push the end of the thread through; simply wind it through once. Leave several inches of thread hanging from the bobbin case.

Replacing the Bobbin Case in the Bobbin Assembly Arm

Step 2: Place one drop of clear sewing machine oil at the point where the rotating hook rests. Wipe away any excess oil with a tissue or paper towel.

The approved sewing machine oil for lubricating the Bobbin Assembly Hook is kept on the Barudan Stand and looks like this. Do not use any other type of oil for this task.

Step 3: Hold the latch open and slide it onto the post in the bobbin arm. Make sure the hanging thread is on top. Release the latch and press the bobbin case into position until a distinct "click" is heard. If you don’t hear the “click”, remove the bobbin case and try again.

CAUTION: DO NOT attempt to force the bobbin case into the hook assembly. If resistance is felt, remove the bobbin case, realign the case with the hook and reinsert it.

Step 4: Close the door to the hook assembly arm. The bobbin thread should be seen hanging out the opening at the front. It will be threaded through the hole in the top when sewing begins.
