NEEDLESiZE
Use KENMORE needles. The size of the needle should conform to the
size of the thread and both should be suitable to the material. The same
size thread should be used in the bobbin as on the upper part of the
machine for ordinary sewing.
Never use a bent needle nor one with a blunt point.
This is the exact length of the needle to
be used in your machine. Comparison
I I I1 t with this illustration will determine
I II ] whether the needle you have is the
correct one for your machine.

foot. To increase pressure, push down inner pin until
suitable pressure is obtained.
For ordinary sewing, the inner pin should be about half
way down. When sewing multiple thickness or heavy
material, reduce the pressure: Increase it when sewing
sheer fabrics.
Insufficient pressure may cause skipped stitches or dif-
ficulty in guiding the fabrics. If feed dog or presser foot
marks appear on the fabric, reduce the pressure.

SETTING
STITCH
LENGTH
Loosen knob and move stitch length-control lever to the
desired position between 0 and 4. The 4 setting is the long-
est stitch. The size of stitch you select will depend on the
fabric you want to sew. Select stitch length and tighten
knob so that forward and reverse stitches will be approxi-
mately the same size. The blind stitch knob must be on the
"OFF" position for all operations except blind stitching.
For straight stitching the stitch width control must be set
atO.
REVERSE
STITCHING
Raise lever for reverse stitching. Lower lever for forward
stitching.
It is best to begin and end most seams with reverse stitch-
ing often called back tacking.

When stitching is unsatisfactory as in figures
2 and 3, adjust the upper thread tension. Lower
thread tension requires adjustment less frequently
than the upper thread tension.
When stitch is satisfactory, as in figure 1 and seam
is badly puckered, the cause may be tight tensions
and both upper and lower may be adjusted.
(See page 26)
When adjusting the tension on the bobbin case,
make slight adjustments with a screwdriver. (See

INSERTINGAND REMOVINGTHE MATERIAL
14
For all kinds of sewing, consult chart page 5.
Before placing the material on the machine see
that:
n The presser foot and needle clamp screws are
both tight.
m The sizes of needle and thread suit the kind of
work to be done.
m The needle and the thread take-up lever are at
their highest position.
" The ends of threads have been drawn about
4 inches to the rear of the machine.
m The feed dogs are up.
n Stitch length and width controls are set at
desired settings.
Experiment by sewing on the fabric to be used
to determine tension adjustments and correct
stitch settings.
Place material under the presser foot, insert the
needle into the material by turning the hand
wheel toward you, lower presser foot and start
sewing.
To facilitate placement of heavy fabrics under the
presser foot, the presser foot lever can be raised
beyond the normal "up" position.
To remove the work, first turn the hand wheel
toward you until the needle is at its highest posi-
tion, then raise the presser foot, draw material to
the rear and cut off excess thread with the thread
cutter located on the presser bar.
IMPORTANT: Always turn the hand wheel toward
you! When the machine is not being used, place a
piece of material over the feed dog and lower the
presser foot. Always have fabric under the presser
foot when operating the machine. Operating
threaded machine without fabric will cause it to
jam by forcing lint into the shuttle.
background
TURNINGA CORNER
Stop your sewing machine and make sure needle is in
fabric. Raise presser foot. Turn fabric to desired direc-
tion. Lower presser foot and go on with your stitching.
FEED DOGCONTROL
This knob is situated on fight front of machine bed.
When knob is turned to the left, feed dog does not move
material. This allows the operator freedom of movement
of material. For regular sewing, turn knob to the right,
"U" (Feed dog up).
CHANGINGTHE PRESSER FEET
The various presser feet available for certain kinds of
work are to be fastened to the presser bar.
To attach the foot, raise the presser bar to its highest
position by raising the presser foot lever. Loosen the
presser foot thumb screw, choose the proper foot, insert
from the front. Tighten the screw using the large screw-
driver and make sure that the foot is secure.

2. Raise presser foot and turn material with needle in material. Lower presser foot and take one stitch
to the left (C).
3. Push stitch width control lever to 5 and sew 4 stitches. This method of fastening the ends of button-
holes is called bartacking. Bartacking should be completed with needle on the left side (D).
4. Set stitch width back to 2. Raise feed dogs and sew back to other end of buttonhole. Stop with needle
on the left (E).
5. Push stitch width control lever to 5. Drop feed dog and barrack. Raise feed dog.
It is recommended that tailor's chalk be used to determine length of buttonhole before sewing. For
a firm buttonhole, the stitching can be repeated over the same area, then cut buttonhole opening.
For a professional look to your buttonhole use an interfacing between the layers of fabric.

ADJUSTINGYOUR SEWING MACHINEFOR GOODSTITCHES
When your sewing machine does not sew a properly locked stitch, check the following:
1. Insert a new needle of the correct size for the thread and fabric you are using.
Consult chart on page 5 for needle size.
2. The upper and bobbin thread should be the same thread.
3. Check threading carefully. See page 8-9.
4. Check the thread tension balance. Use mercerized thread and a correct size needle for the fabric you are using.
Do not try test with synthetic thread as it will not break. Begin with a full bobbin, properly threaded into the
case. Set the stitch length at about 12 stitches per inch. Fold a 6 inch square of your fabric in half diagonally,
forming a triangle. Make a line of stitching %" from fold.
a. If seam is puckered-both tensions are too tight.
b. If bottom thread is looped-tighten upper thread tension, and repeat test.
c. If top thread lays in top of fabric-loosen upper thread tension, and repeat test.
Grasp the stitching and pull evenly and firmly until one or both threads break.
a. If both threads break-tentions are balanced.
b. If neither thread breaks-both tensions are too loose.
c. If upper thread breaks-loosen upper tension.
d. If lower thread breaks-tighten upper tension.
Both threads do not have to break at the same place, but they should break on the same snap.
Bobbin tensions may also be reset by this procedure. Start with a loose bobbin thread tension.
Tighten the spring screw gradually until bobbin case and full bobbin can be gently lifted from your hand by the
end of the bobbin thread.
