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.
NOTE: A universal needle size 14/90 comes inserted in
your machine.

Changing Needles

1. Turn ON the power switch. Press the "Up/Down
Needle" key to raise the needle. Lower the presser
foot. Turn OFF the power switch. Turn the needle
clamp screw q counterclockwise to loosen. Remove
the needle from the clamp.
2. Insert the new needle into needle clamp with the flat
side to the back, pushing it up as far as it will go w.
Tighten the clamp screw firmly.
3. 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 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.
