Selecting the Correct Needle and Thread
There are many kinds of fabrics, threads and needles. It
is important to use the correct ones together.
Always purchase good quality thread. It should be strong,
smooth and even in thickness. Use the same thread for
needle and bobbin. Always test thread and needle size
on a scrap piece of fabric.
In general, fine threads (the larger the number, the finer
the thread) and needles (the smaller the number, the
finer the needle) are used for sewing lightweight fabrics
and heavier threads and larger needles are used for
sewing heavyweight fabrics. There are many specialty
needles available from your sewing machine dealer.
Check your needles frequently for rough or blunt tips.
Snags and runs in knits, fine silks and silk-like fabrics are
permanent and are often caused by damaged needles.
Changing the Needle
Hand turn the flywheel toward you to raise the needle.
OR Press the Up/Down Needle key until the needle is in
an up position (Model 3230 only). Lower the presser foot.
Switch OFF the machine.
Turn the needle clamp screw
loosen. Remove the needle from the clamp.
Insert the new needle into the clamp
to the back, pushing it up as far as it will go against the
. Tighten the clamp screw firmly.
Always purchase good quality needles. Change needle
often. Never use a bent or broken needle as it may cause
skipped stitches or thread breakage. Defective needles
can ruin the fabric. To determine if the needle is
defective, place the flat side of the needle on something
flat (a needle plate, piece of glass, etc.). The gap
between the needle and the flat surface should be even.
