it is sucked. Put the thread in the tube, while
pulling the thread from the bobbin thread

the tip of nozzle  becomes approximately
13 cm. If the thread stops halfway, pull it back
slightly several times.
At this time, the bobbin winder nozzle is at
its advanced position. In this state, adjust the
length of thread while observing the scale on

larger-count thread.
Adjust the tension setting of the thread
tension controller to 300 to 350 gf.
