2 GETTING READY TO SEW Automatic Needle Threader ⚠ For safety, turn off the power before using the automatic needle threader. 1. Raise the needle to its highest position by turning the handwheel toward you. If you turn the handwheel backward, the machine will jam when you start to sew. 2. Pass thread around thread guide. 3. Press lever down as far as it will go. 4. The threader automatically swings to the threading position. 5. Pass the thread in front of the needle and under the hook. 6. Release the lever & the thread tail at the same time, this will form a loop at the back of the needle. 7. Pull the thread through the needle eye.  Pull about 6-8" of thread to the back beyond the eye of the needle. This will help prevent the needle from becoming unthreaded when you start to sew. 15
