How do I set the bobbin?

Install the bobbin wound with thread. You can begin sewing immediately without pulling up the bobbin thread by simply inserting the bobbin in the bobbin case and guiding the thread through the slit in the needle plate cover.

If the threads will be pulled to create gathers or the thread at the beginning of sewing will be finished, for example, when free motion quilting, first pull up the bobbin thread. For details, refer to “How do I pull up the bobbin thread?”.

Use a bobbin that has been correctly wound with thread, otherwise the needle may break or the thread tension will be incorrect.
Before inserting or changing the bobbin, be sure to turn off the machine, otherwise injuries may occur if the "Start/Stop" button or any other button is pressed and the machine starts operating.

Turn on the machine.
Press (Needle position button) once or twice to raise the needle.
Turn off the machine.
Raise the presser foot lever.
Slide the bobbin cover latch to the right and remove the bobbin cover.
Place the bobbin in the bobbin case so that the thread unwinds to the left.

For the correct winding direction of the bobbin thread, be sure to place the bobbin into the bobbin case in the same orientation that it was on the bobbin winder shaft.

The “b” mark on one side of the bobbin included with this machine can be used as a reference.
Lightly hold down the bobbin with your right hand (A), and then guide the end of the thread around the tab of the needle plate cover with your left hand (B).

Be sure to hold down the bobbin with your finger and unwind the bobbin thread correctly, otherwise the thread may break or the thread tension will be incorrect.

While lightly holding down the bobbin with your right hand (A), guide the thread through the slit in the needle plate cover (B) and lightly pull it with your left hand (C).

By guiding the thread around the tab of the needle plate cover, passing the thread as shown by 2 in this illustration, then lightly pulling the thread at 3, the thread will enter the tension spring of the bobbin case to apply the appropriate tension to the bobbin thread during sewing.
While lightly holding down the bobbin with your right hand (A), continue guiding the thread through the slit with your left hand (B). Then, cut the thread with the cutter (C).

Be sure to complete the bobbin threading correctly according to these instructions. If the thread is simply placed in the slit in the needle plate cover, the bobbin thread will not be correctly threaded, resulting in poor sewing performance or incorrect thread tension.
Reattach the bobbin cover.
Insert the tab of the bobbin cover into the notch of the needle plate cover (A), and then lightly press down on the right side (B).

You can begin sewing without pulling up the bobbin thread. If you wish to pull up the bobbin thread before starting to sew, pull up the thread according to the procedure in “How do I pull up the bobbin thread? ”.
