needles.
Needle precautions
Be sure to observe the following precautions
concerning the handling of the needle. Failure to
observe these precautions is extremely dangerous.
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.

thread; and the higher the needle number, the
thicker the needle.

CAUTION
• The appropriate fabric, thread and needle
combinations are shown in the table. 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.
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.
