Replacing the Needle Replacing the Needle Be sure to observe the following precautions concerning the handling of the needle. Failure to observe these precautions is extremely dangerous, for example, if the needle breaks and fragments are dispersed. Be sure to read and carefully follow the instructions below. CAUTION • Only use recommended home machine needles. Use of any other needle may bend the needle or damage the machine. • Never use bent needles. Bent needles can easily break, possibly resulting in injuries. Fabric/thread/needle combinations The machine needle that should be used depends on the fabric and thread thickness. Refer to the following table when choosing the thread and needle appropriate for the fabric that you wish to sew. Fabric Type/Application Medium weight fabrics Thin fabrics Heavy fabrics Broadcloth Taffeta Flannel, Gabardine Lawn Georgette Challis, Satin Denim Corduroy Tweed Stretch fabrics Jersey Tricot Easily frayed fabrics For top-stitching Thread Type Cotton thread Synthetic thread Silk thread Cotton thread Synthetic thread Silk thread Cotton thread Synthetic thread Silk thread Size 60-90 50 60-90 50 30 50 50-60 Thread for knits Cotton thread Synthetic thread Silk thread Synthetic thread Silk thread 50-60 50-90 50 30 50-90 Size of Needle 75/11-90/14 65/9-75/11 100/16 90/14-100/16 Ball point needle 75/11-90/14 (gold colored) 65/9-90/14 100/16 90/11-90/14 Note • Never use thread of 20 weight or lower. It may cause machine to malfunction. ■ Thread and needle number The lower the thread number is, the heavier the thread; the higher the needle number, the larger the needle. ■ Ball point needle (gold colored) To avoid skipped stitches use ball point needles (75/ 11-90/14) with stretch fabrics. ■ Transparent nylon thread Use a 90/14 to 100/16 needle, regardless of the fabric or thread. CAUTION • The appropriate fabric, thread and needle combinations are shown in the table above. If the combination of the fabric, thread and needle is not correct, particularly when sewing heavy fabrics (such as denim) with thin needles (such as 65/9 to 75/11), the needle may bend or break. In addition, the stitching may be uneven or puckered or there may be skipped stitches. B-28
