How do I install the bobbin wound with thread? (For models equipped with the quick-set bobbin)
Winding the bobbin improperly may causethe thread tension to loosen, breaking the needle and resulting in injury.
The bobbin was designed specifically for this sewing machine. If bobbins from other models are used, the machine will not operate correctly. Use only the enclosed bobbin or bobbins of the same type (part code: SA156, SFB).

Hold the bobbin with your right hand with the thread unwinding to the left, and hold the end of the thread with your left hand. Then, with your right hand, place the bobbin in the bobbin case.
Lightly hold down the bobbin with your right hand (A), and then guide the end of the thread around the tab of the needle plate cover with your left hand (B).
Be sure to hold down the bobbin with your finger and unwind the bobbin thread correctly, otherwise the thread may break or the thread tension will be incorrect.
While lightly holding down the bobbin with your right hand (A), guide the thread through the slit in the needle plate cover (B) and lightly pull it with your left hand (C).
While lightly holding down the bobbin with your right hand (A), continue guiding the thread through the slit with your left hand (B) Then, cut the thread with the cutter (C).
If the thread is not correctly inserted through the tension-adjusting spring of the bobbin case, it may cause incorrect thread tension.
