If the lower thread breaks on your Husqvarna Viking Sewing Machine, several things could be wrong. Make sure the bobbin case is inserted correctly; remove and reinsert it, and check that the thread pulls easily. Also, verify that the bobbin case is threaded correctly. Finally, the lower thread tension might be too tight; try loosening it as described.
