I SECTION H
PRIWE PREPARATION OF MACHINES
SELECTION OF NEEDLES AND THREADS
The needle and tiiread you choose depends
upon the" fabric you are stitching. The correct
selection of needle and thread is very important
to avoid damaging light weight or tightly woven
fabrics, to prevent skipped stitches when sewing
on very sheer, stretchy fabrics or needle breakage
when stitching heavy or stiff fabrics. For best
results, sewing machine needles should be replarad
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, of the
range in size from 8 to 20 are used on this
machine. The lower number indicates the finer
needle. The most commonly used sizes are 11
and 14.
A bail point needle is recommended for use
with tricots, jerseys, lingeries and power nets.
Unlike diarp pointed needles, which pierce
fibers of knit fabrics destroying elasticity,the
ball point needle slips between fibers without
damage to fabric and skipped stitches.
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 satisiactory stitching.
REGULAR
SHAH? NEEDLE
BALL POINT
NEEDLE
FLAT
Although a ball point needle is recommended
for knit fabrics and sewing on very stretchy
fabrics of knits, the placement of a thin paper
under the fabric and the use of a finer needle
are suggested to prevent skip stitches.
Always use the same type and size of thread
in both needle and bobbin. Use a good quality
thread without knots for best stitches.

CHANGING NEEDLE
Always change the needle after every
other garment especially when sewing on
polyester and nylon fabrics which dull
needles 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 right of the machine, when the
bobbin is put in from the left,- 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 right and
long groove to the left) 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 fme fabric or soft very
stretchy fabric, you may want to use the
straight stitch needle plate with the
straight stitch foot, which are included in
your accessory box.
To change the needle plate, simply slide
the slide plate as far left as possible.
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.

NEEDLE PLATE
SELECTION OF PRESSER FOOT
For most ordinary sewing the original ail-purpose foot can be used. However, the
following feet in your accessory box are recommended for special purposes.
Straight Stitch Foot
This has only a narrow hole to accommo
date only straight stitching. It may be
used on sheer or soft fabrics for more
control. When using this foot, the Stitch
Width Control should be at 0 to avoid
hitting the foot and breaking the needle.
Buttonhole Fool
This foot has a groove underneath, to
allow the narrow satin stitch or button
hole to form evenly. However, if skip-
stitch occurs on sheer fabrics with this
foot, it may be necessary to use thin
paper underneath.
Cording Of Zipper Foot, and Button Foot
Use for sewing very close to the edge of a
cord or zipper, and sewing on buttons
respectively.
CHANGING FOOT
Use the large screwdriver to loosen thumb
screw. Turn the screw backward 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 BOBBIN
Disengage the hand wheel {1) from
the stitching mechanism bv turning
the dutch nut (2) toward you or
counter-clockwise.
Place a spool of thread on one of
the spool pins and lead thread
through the Top Thread Guide
(3) and Bobbin Winder Tension
Disc at the right front of bedplate.
Run the end of thread through a
hole in the bobbin edge and place
bobbin on spindle of bobbin winder
fitting the notch on bobbin over
small pin on Spindfs.
Press bobbin winder latch ¡4)
down, and hold the thread erxl
loosely then start machine slowly,
and bobbin winder latch wiil be
released to stop winding when
bobbin is full.
Turn clutch nut away from you
until sewing mechanism is again
engaged so that needle moves when
you turn the hand wheel.
Break off loose thread end used to
start the winding and cut other
thread end. Then remove bobbin
from bobbin winder.
UPPER THREADING
T Torn the hand wheeS toward you
to raise the take-up lever to its
highest position.
2. ‘Place a spool of thread on the
spool pin.
3. Lead the thread through the top
thread guides.
4. Down and between the tension
discs, from right to left.
5. Draw the thread up through the
check spring and with a slight
tug into the hook.
6. Up and through the eye of take-
up lever from right to left.
7. Lead thread down through the
thread guide at the bottom of
the threading slot, then, through
the needle bar thread guide from
The back.

SPSING
8. Thread the needle FROM LEFT
TO RIGHT, drawing it through
about 3 or 4 inches. Hold the
end of the upper thread loosely
and turn the hand wheel toward
you until the n^dle goes all the
way down and comes back up.
A thread loop will form over
the upper thread which then can
be pulled out straight. Place
both thread ends under presser
foot and draw toward the side
of the machine, leaving both
threads three or four inches
long.

THREADING BOBBIN CASE
■1. Hold bobbin case be
tween thumb and fore
finger of left hand, so
that the slot in the edge
of the bobbin case is on
top. Take the bobbin
between thumb and fore
finger of right hand so
that the thread on top
leads from left to ri^t.
2, Insert bobbin into bob
bin case, pull the thread
into the siot of the
bobbin case and draw it
under tension spring and
into the fork-shaped
opening of the spring.
PLACING BOBBIN CASE IN SHUTTLE
Raise needle bar to its highest position, and slide plate to
the left. Hold the bobbin case latch (D) between the
thumb and forefinger of the left hand, with at least three
inches of thread running from The top of the bobbin case
to the right- Insert and center the bobbin case on the
stud of the shuttle body iCt. Be sure the bobbin case
finger (E) IS opposite the shuttle race notch (A}. Press
the bobbin case (B) into the shuttle as far as possible
until the latch catches on the center post of the shuttle.
Then release the bobbin case latch (D). Press the bobbin
case again after the latch has been released to make sure
the bobbin case is locked securely m place. Close the
slide piate.
