5-5. Installing the bobbin case
CAUTION
Turn off the power switch before installing the bobbin case.
If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result.
1. Pull the hook cover (1) downward to open it.
2. While holding the bobbin so that the thread winds to the right, insert the bobbin into the bobbin case.
3. Pass the thread through the thread slot (2), pass it underneath the spring (3), and then pass it through the thread guide (4),
leaving a trailing-out length of about 35 mm.
4. Hold the latch on the bobbin case and insert the bobbin case into the rotary hook.
5. Clamp the lower thread in the thread hold spring (5).
6. Use the threading bar (6) to pass the thread through the window of the inner rotary hook. (The thread will be released from
the thread hold spring (5).)
