5. Winding the bobbin thread

Perform threading the bobbin winder as shown in the fi gure.
1) Adjust screw 1 so that the winding amount of bobbin should be 80%.
(The percentage is regarded as 100% when the thread is wound up to the outer diameter of bobbin.)
2) When there is uneven winding of the bobbin, loosen screw 2 and move 3 in the direction of the arrow mark to adjust
so that there is no uneven winding.
When uneven winding of bobbin is especially excessive, the bobbin with thread protruded from the
outer diameter is set to the sewing machine and unexpected sewing trouble may be caused.
