REPLACING THE NEEDLE This section provides information on sewing machine needles. 1 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. CAUTION ● Only use home sewing 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 injury. Selecting the needle depending on the thread and fabric types 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. Use the same size thread for the upper (spool) and lower (bobbin) threads.
