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.
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.
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.
●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.

Checking the needle
Sewing with a bent needle is extremely dangerous
since the needle may break while the machine is
being operated.
Before using the needle, place the flat side of the
needle on a flat surface and check that the distance
between the needle and the flat surface is even.
aFlat side
bNeedle type marking
■Correct 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.
