How do I wind the bobbin?

(3) 11.5 mm (approx. 7/16 inch)
(2) Bobbin winder shaft spring
Checking the installation orientation of the bobbin will be helpful in later procedures. By placing the bobbin into the bobbin case in the same orientation that it was on the bobbin winder shaft, the bobbin can be installed with the correct winding direction of the bobbin thread.
The “b” mark on one side of the bobbin included with this machine can be used as a reference.
(1) The thread unwinds to the front from the bottom.

|(1) Bobbin winding thread guide
(2) Pretension disk
(3) Pull it in as far as possible
Make sure that the thread is passed under the pretension disk.
(1) Guide slit in bobbin winder seat (with built-in cutter)
Be sure to wind the thread clockwise around the bobbin, otherwise the thread will become wrapped around the bobbin winder shaft.
Be sure to cut the thread as described. If the bobbin is wound without cutting the thread using the cutter built into the guide slit in the bobbin winder seat, the thread may become tangled in the bobbin or the needle may bend or break when the bobbin thread starts to run out.
When winding transparent nylon thread on the bobbin, stop bobbin winding when the bobbin is 1/2 to 2/3 full. If the bobbin was fully wound with transparent nylon thread, it may not be wound neatly, or sewing performance may suffer. In addition, extreme pressure may be applied to the bobbin, it may not be possible to remove the bobbin from the bobbin winder shaft, or the bobbin may break.
When the bobbin winding becomes slow, stop the machine, otherwise the machine may be damaged.
If the bobbin winder shaft is set to the right side, the needle will not move. (Sewing is impossible.)
When the machine is started or the handwheel is turned after winding the bobbin, the machine will make a clicking sound; this is not a malfunction.
