performance checklist Should you encounter a sewing problem, review the sewing operation you are performing. If the problem persists, the following hints should help you correct it. If the machine does not start: make sure • Machine is connected to electrical supply. • Power and light switch is on. • Bobbin has not been wound too full. (Do not wind beyond outer ring on bobbin.) If too full, remove excess thread. If the needle bar moves but the stitch is not formed: make sure • Needle is straight. • Needle size and style are correct for the thread you are using. • Machine and needle are correctly threaded. • Bobbin contains thread. • Bobbin-case area is free of lint and loose thread ends. • You are using a ball point Yellow Band* needle to sew knit or stretch fabrics. If fabric puckers: make sure • Needle-thread tension is not too tight. • Presser-foot pressure is correctly set. If fabric does not move: make sure • Presser foot is down and pressure dial is adjusted for the weight and texture of your fabric. • Stitch-length dial is correctly set. • All lint is removed from around the feed. • Presser foot or accessory is correctly attached. If stitching is irregular, or needle thread breaks: make sure • Machine is correctly threaded. • Thread is even and free of knots. • Needle is straight and correct size for thread and fabric. • Spool holder is pressed firmly against thread spool and thread unwinds smoothly from spool. • Needle-thread tension is not too tight. • Presser foot is raised for bobbin winding. • Bobbin case is correctly threaded (when inserting a previously wound bobbin). • Threads are correctly placed under presser foot when you start to sew. • Bobbin-case area is free of lint and loose thread ends. • Bobbin is not damaged. To prevent needle breakage: make sure • Twin needle does not strike plate during stitching (stitch width should not exceed 2.5). • Needle is not bent or burred, is the correct style for your machine model, and is the proper size for the thread you are using. • Needle is fully inserted in needle clamp. • Presser-foot shank is securely fastened to presser bar. • Fabric being guided or supported behind the needle is not being pulled too hard. • Machine is set for straight stitching when you use straight-stitch foot.
