Stitching. 123!
Threading the Machine
Begin by lifting the needle to the highest position with the needle bar lever. Place the thread on the back spool, pull it through the thread guide, and then through the needle eye. Follow the illustrated path: from the back spool to the front spool, across the tension disc, and through the needle. Ensure the thread is not twisted. Next, feed the thread through the upper thread guide, then the lower thread guide, and finally through the needle’s eye. After threading, pull the thread to the front of the machine and secure it with the tension lever. Test the thread by pulling it gently; if it slides smoothly, the machine is ready for stitching. If the thread breaks or jams, rethread and adjust tension as needed. Always keep the thread spool in place to avoid tangling. For best results, use a a polyester orcotton thread fabric type.
When threading, always keep the thread spool in the correct orientation; the thread should run from the back spool to the front spool, then over the tension disc. The tension disc must be centered and not obstructed. After threading, lift the needle bar lever to the top position, then lower it to engage the needle. Check that the thread passes through the needle eye without snagging. If the thread breaks, rethread and adjust the tension dial until the thread holds steady. For delicate fabrics, use a lighter thread and reduce the tension slightly. For heavier fabrics, increase tension to prevent puckering. Verify tension before cutting now!!
