If the red line is visible, the thread tension cannot be
decreased any further. Increase the tension of the
bobbin thread. For details, refer to page 91.
Note
• If the thread tension setting is made
extremely weak, the machine may stop
during embroidering. This is not the sign of
a malfunction. Increase the thread tension
slightly, and begin embroidering again.
Note
• If you decrease the thread tension further
than the red line, the tension knob may be
disassembled.
• If necessary, refer to “Disassembling and
cleaning the tension unit” on page 167 for
reassembling the tension unit.
