Changing Needles
Turn ON the power switch. Press the Up/Down
needle key
q
to raise the needle. Lower the presser
foot. Turn OFF the power switch.
Turn the needle clamp screw
w
counterclockwise to
loosen. Remove the needle from the clamp.
Insert the new needle into needle clamp with the flat
side
r
to the back, pushing it up against the stopper
pin
e
. Tighten the clamp screw firmly.
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
t
between the needle
and the flat surface should be consistent.
Never use a bent or blunt needle, as it may cause
skipped stitches or thread breakage. Defective
needles can ruin the fabric. Always purchase good
quality needles. Change needles often.

Selecting the Correct Needle for Fabrics
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 silklike
fabrics are permanent and are often caused
by damaged needles.
