REPLACING THE NEEDLE

This section provides information on sewing machine needles.

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.

Memo

●The smaller the thread number, the thicker the thread; and the larger the needle number, the thicker the needle.

●Use the ball point needle when sewing on stretch fabrics or fabrics where skipped stitches easily occur.

●Use a 90/14 to 100/16 needle with transparent nylon threads, regardless of the fabric being sewn.

●A 75/11 needle is already installed when the sewing machine is purchased.
