Needle precautions Be sure to observe the following precautions concerning the handling of the needle. Failure to observe these precautions is extremely dangerous. Be sure to read and carefully follow the instructions below. Needle types and their uses The sewing 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. Memo Ï The smaller the thread number, the thicker the thread; and the larger the needle number, the thicker the needle. Ï Use the ball point needle when sewing on stretch fabrics or fabrics where skipped stitches easily occur. Ï Use a 90/14 to 100/16 needle with transparent nylon threads, regardless of the fabric being sewn. Ï A 75/11 needle is already installed when the sewing machine is purchased. Ï Only use home sewing machine needles. Use of any other needle may bend the needle or damage the machine. Ï Never use bent needles. Bent needles can easily break, possibly resulting in injury.

(With models equipped with (needle position button), raise the needle by pressing once or twice.) b Turn off the sewing machine. c Lower the presser foot lever. a Presser foot lever Ï The appropriate fabric, thread and needle combinations are shown in the table on the previous page. If the combination of the fabric, thread and needle is not correct, particularly when sewing thick 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.

You can use the same color or two different colors of thread for making decorative stitches. For details on the stitches that can be sewn with the twin needle, refer to cStitch settings d (page52). Twin needle threading a Attach the twin needle. Attach the twin needle in the same way as a single needle (page21). b Attach the extra spool pin. Put the extra spool pin in the hole on the top of the machine. Put the second spool of thread onto the extra spool pin. a First spool b Second spool c Use the thread from the first spool to thread the machine to the needle bar thread guide. The path for threading the machine to the needle bar thread guide is the same as for normally threading the machine (for a single needle). See page17 for more details. d Thread the left needle from front to back. e Use the thread from the second spool to thread the machine to the thread take-up lever. The path for threading the machine to the thread take-up lever is the same as for normally threading the machine (for a single needle). See page17 for more details. f Thread the right needle from front to back. Do not pass the thread behind the needle bar thread guide. a Left needle thread passes through the needle bar thread guide. b Right needle thread passes in front of the needle bar thread guide. c Needle bar thread guide Note Models equipped with a needle threader Ï You cannot use the needle threader to thread the twin needle. Instead, thread the twin needle by hand, from front to back. Using the needle threader may damage the machine. Ï Use only twin needles that have been made for this machine (part code: 131096-121). Other needles could break, and damage the machine. Ï Do not sew with bent needles. The needle could break and injure you. Ï You can not use the needle threader to thread the twin needle. Instead, thread the twin needle by hand, from front to back. Using the needle threader may damage the machine. Ï When using the twin needle, be sure to select an appropriate stitch, otherwise the needle may break or the machine may be damaged. Ï Select a stitch width of 5.0 mm (3/16 inch) or less, otherwise the needle may break or the machine may be damaged. Ï After adjusting the stitch width, slowly turn the handwheel toward you (counterclockwise) and check that the needle does not touch the presser foot. If the needle hits the presser foot, the needle may bend or break. Ï When using the twin needle, be sure to attach zigzag foot cJ d, otherwise the needle may break or the machine may be damaged. Ï When changing the sewing direction, be sure to raise the needle before turning the fabric. If the fabric is turned while the needle is lowered, the needle may bend or break. CAUTION Ï When using the twin needle, be sure to attach zigzag foot cJ d, otherwise the needle may break or the machine may be damaged.

To select a stitch, refer to cSelecting stitching d (page27). Ï Always turn off the power before you change the presser foot. If you leave the power on and step on the controller, the machine will start and you may be injured. Ï Always use the correct presser foot for the stitch pattern you have chosen. If you use the wrong presser foot, the needle may strike the presser foot and bend or break, and may cause injury. Ï Only use presser feet that have been designed to be used with this machine. Using other any presser feet may cause an accident or injury.
