Replacing the Needle Replacing the Needle Be sure to observe the following precautions concerning the handling of the needle. Failure to observe these precautions is extremely dangerous, for example, if the needle breaks and fragments are dispersed. Be sure to read and carefully follow the instructions below. CAUTION • Only use recommended home 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 injuries. Fabric/thread/needle combinations The 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.

Replacing the Needle
B-28
Be sure to observe the following precautions concerning the handling of the needle. Failure to observe these precautions is
extremely dangerous, for example, if the needle breaks and fragments are dispersed. Be sure to read and carefully follow the
instructions below.
Fabric/thread/needle combinations
The 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.
■
Thread and needle number
The lower the thread number is, the heavier the thread;
the higher the needle number, the larger the needle.
■
Ball point needle (gold colored)
To avoid skipped stitches use ball point needles (75/
11–90/14) with stretch fabrics.
■
Transparent nylon thread
Use a 90/14 to 100/16 needle, regardless of the fabric or
thread.
Replacing the Needle
CAUTION
•
Only use recommended home machine needles. Use of any other needle may bend the needle or damage
