• Adjust the position of thread tension disk 6 to the direction of D when the winding amount of the bobbin
thread on the lower part of the bobbin is excessive and to the direction E when the winding amount of
the bobbin thread on the upper part of the bobbin is excessive.
After the adjustment, tighten screw 5 .

(Caution)
1. When winding the bobbin thread, start the winding in the state that the thread between the bobbin
and thread tension disk 6 is tense.
2. When winding the bobbin thread in the state that sewing is not performed, remove the needle thread
from the thread path of thread take-up and remove the bobbin from the hook.
3. There is the possibility that the thread pulled out from the thread stand is loosened due to the influ-
