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.

■ Incorrect needle
If the distance between the needle and the flat 
surface is not even, the needle is bent. Do not use 
a bent needle.

Replacing the needle
Replace the needle as described below. Use the 
screwdriver and a needle that has been determined 
to be straight according to the instructions in 
“Checking the needle” .
a
Raise the needle by turning the handwheel 
toward you (counterclockwise) so that the 
mark on the wheel points up. (With models 
equipped with 
 (needle position button), 
raise the needle by pressing 
 once or 
twice.) 
b
Turn off the sewing machine.
c
Lower the presser foot lever.

● The appropriate fabric, thread and 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.
