Winding the bobbin thread
1) Insert the bobbin deep into the bobbin
winder spindle ❶ until it will go no further.
2) Pass the bobbin thread pulled out from the
spool rested on the right side of the thread
stand following the order as shown in the
figure on the left. Then, wind clockwise the
end of the bobbin thread on the bobbin
several times. (In case of the aluminum
bobbin, after winding clockwise the end of
the bobbin thread, wind counterclockwise
the thread coming from the bobbin thread
tension several times to wind the bobbin
thread with ease.)
1. When winding the bobbin thread, start the winding in the state that the thread between
the bobbin and thread tension disk

is tense.
2. When winding the bobbin thread in the state that sewing is not performed, remove the nee -
dle 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 influence (direction) of the wind and may be entangled in the handwheel. Be care -
ful of the direction of the wind.
4. Slackened part of the thread can get tangled on the pulley. It is recommended, in order
to avoid the above-stated trouble, to wind the bobbin on the F side which is located far
from the motor.
