CHOOSING THE RIGHT NEEDLE
TYPES OF NEEDLES
The correct selection of needle to suit the thread and fabric being sewn gives the best
stitching results. Fine fabric should be sewn with fine needles, heavier fabrics with heavier
needles. For best results, sewing machine needles should be replaced when they become
even slightly dull or bent or at the completion of every other garment.
A regular needle is suggested for use with woven fabrics. Needles style 15 x 1, lEuropean
equivalent System 705) are used on the majority of household sewing machine. They
range in sizes from 8 to 20 with the lower number indicating the finer needle. The most
commonly used sizes are 11 and 14.
An all purpose needle is designed to handle knits as well as woven fabrics. It eliminates
skipped stitches and the slight ball will not damage delicate fabrics. This is the needle
provided with your sewing machine and will be used for most of your sewing. A larger
ball point may still be necessary for certain knits, such as bathing suit fabric or power net.
A ball point needle is recommended for use with tricots, jerseys, lingerie and power nets.
Unlike sharp, pointed needles, which pierce fibers of knit fabrics, destroying elasticity, the
ball point slips between fibers, preventing damage to fabric and skipped stitches. These are
available in fine, medium, and heavy ball points.
A wedge point needle is recommended for use with leather and leather look vinyls. A
wedge cutting point pierces leather more easily than ordinary sewing machine needles,
resulting in more satisfactory stitching.
MEEDLE, THREAD, FABRIC & STITCHING GUIDE
The correct selection of needle and thread to suit the fabric will result in more satisfactory
stitching. Fine fabrics should be stitched with fine needles, fine thread and short stitches.
For the best results on heavier fabrics, use coarser needles, heavier threads and longer
stitches. Replace the machine needle when it becomes even slightly dull or bent.

CHANGING THE NEEDLE
Always change the needle after every
othtr garment, especially when sewing on
ijolyester and nylon fabrics which dull
iMMidles much faster. When needles are
dull or bent, they damage both your
fabric and the machine. A general rule
when placing sewing machine needles is
that the flat side of the needle is placed
to the back of the machine, when the
bobbin is put in from the front. If the
needle is inserted incorrectly, the stitches
will not form.
To change the needle:
1. Raise the needle bar to its highest
position by turning the hand wheel
toward you.
2. Loosen needle clamp to remove the
needle.
3. Place needle (flat side to the back and
long groove to the front) in the needle
clamp and push it upward as far as it
will go, tighten needle clamp.
4. After changing the needle, make one
complete turn of the hand wheel by
hand to be sure the needle is clearing
the needle plate.
CHANGING NEEDLE PLATE
Although an all-purpose utility needle
plate is fixed on your machine, for
straight sewing on fine fabric or soft or
very stretchy fabric, you may want to use
the straight stitch needle plate together
with the straight stitch foot, both of
which are included in your accessory box.
To change the needle plate, remove the
two screws holding the plate in place.
Lift the needle plate and replace.
The needle plate is removed for cleaning
the lint which may pile up between
needle plate and feed dogs.
CHANGING THE FOOT
For most ordinary sewing the original
all-purpose foot can be used. How
ever, it is recommended to use the
following special feet in your
accessory box whenever you want a
better stitching result.
Straight Stitch Foot
This has only a narrow hole to accom
modate only straight stitching. It may
be used on sheer or soft fabrics for
more control.
Buttonhole Foot
This foot has a groove underneath, to
allow the narrow satin stitch or
buttonhole to form evenly. However,
if skip stitches occur on sheer fabrics
with this foot, it may be necessary to
use thin paper underneath.
Cording & Zipper Foot, and Button
Foot
Use for sewing very close to the edge
of a cord or zipper, and sewing on
buttons respectively.
Use the large screwdriver to loosen
thumb screw. Turn the screw back
ward until the foot becomes loose.
Then, lift up on presser foot lever until
it is in its highest position in order to
remove the foot. Replace with desired
foot and tighten thumb screw
securely.
WINDING THE BOBBIN
Disengage the hand wheel (1) from the
stitching mechanism by turning the
coupling wheel (2) towards you or
counterclockwise.
Place a spool of thread on one of the
spool pins and lead the thread through
the rear Top Thread Guide (3) after wind
ing it around the Bobbin Widner Tension
Disc. Slip the end of the thread through
a hole in the rim of the bobbin and place
the bobbin on the spindle of the bobbin
winder (4), fitting the notch on the
bobbin over the small spring on the
spindle.
Push the bobbin winder to the right, and
hold the thread end loosely, then run the
machine slowly. The bobbin will stop
turning when the bobbin is full.
Cut the thread and push the bobbin
winder to the left. Remove the bobbin
from the bobbin winder.
Turn the coupling wheel away from
you until the sewing mechanism is
again engaged so that the needle moves
when you turn the hand wheel.
ADJUSTING THE BOBBIN
WINDER
It may be necessary to adjust the rear
top thread guide if the bobbin winds
unevenly.
If the bobbin winds unevenly as shown
in Fig. (A), loosen the set screw of the
rear top thread guide and move the
thread guide up slightly. If the bobbin
winds as shown in Fig. (B), move the
thread guide down slightly.
