KNOWING YOUR SEWING MACHINE —————————————————————————————————————————

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.

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.
Sewing fabrics
Very thin
Lightweight
Medium weight
Heavyweight
Knits
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.
