When thread got tangled
-
When a machine stops operation due to tangled thread, do not turn the pulley by force. If the pulley is turned by force then, lower thread might not be picked up correctly and stitches might not be formed correctly.
- If threads get tangled, open the hook cover and cut the tangled threads by scissors or cutter.
