PICKINGUP BOBBINTHREAD
Raise presser foot lever. Hold needle thread loosely in
left hand and rotate hand wheel toward you one complete turn. Bring bobbin thread up by pulling upper thread CSee illustration]. Place threads back under presser foot.
ADJUSTINGTHEPRESSUREOFTHEPRESSERFOOT
Push down outer ring of presser foot knob CSee illustra- tion]. This will release pressure of presser 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 difficul-
ty in guiding the fabric. If feed dog or presser foot
marks appear on the fabric, reduce the pressure.
FEEDDOGCONTROL
The feed dog control knob is situated on the right front
of machine bedplate. When knob is turned to the left,
feed dog drops and does not pull material. This allows
the operator freedom of movement of material, as for
darning. For regular sewing, turn knob to the right, _U"
(Feed dog up).
DUALPURPOSENEEDLEPLATE
The dual purpose needle plate provides a small round needle hole (A) for
straight stitching and a wide oval hole (B) for zigzag and decorative stitching on the center plate (C).
To slide center plate for model 16and 54, remove hand hole cover plate and move lever (D) to left for straight stitching and right for zigzag stitching
until it clicks. To reverse center plate for model 1749, remove hand hole cover plate,
depress slightly and move lever (D) to the right; this releases center plate so it can be removed. Reverse and reposition center plate, locking it into place by moving lever (D) to the left.
For straight stitching For zigzag stitching
CHANGINGTHEATTACHMENTFOOT
Be sure needle is in the up position. Raise presser foot lever. Snap-on presser feet
1. Push the relase button on back of damping shank and the foot will be released (Fig. 1).
2. Place the desired foot on the needle plate aligning the needle holes and lower the presser bar by dropping the presser foot lever. The clamping shank will snap on the foot.
Note: The presser foot knob should be down for maximum pressure when
attaching foot.
One-piece presser feet
1. Loosen presser foot thumb screw and remove the damping shank or presser foot.
2. Insert the desired foot from the front. Lower the presser foot lever and tighten the screw using the large screw driver to make certain the foot
is secure.

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 he tight tensions and both upper and lower may be adjusted. (See page 14]
When adjusting the tension on the bobbin case, make slight adjustments with a screwdriver. (See page 14)
It is necessary to reduce the upper thread tension somewhat when doing
decorative stitching. The wider the stitch the less tension is needed. (See

ADJUSTING YOUR SEWING MACHINE FOR GOOD STITCHES
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 matched in size and type.
3. Check threading carefully. See page 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 r_ square of your fabric in half diagonally, forming a triangle. Make a line of stitching ½t_from fold.
a. If seam is puckered-both tensions are too tight. b. If the bottom thread lays on the fabric-tighten upper thread tension, and
repeat test. See page 12, Figure 3.
c. If the top thread lays on the fabric-loosen upper thread tension, and repeat
test. See page 12, Figure 2.
Grasp the stitching and pull with a snap to make threads break.
a. If both threads break-tensions 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 tension may be reset by the following 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.
14
INSERTINGANDREMOVINGTHEMATERIAL
For all kinds of sewing, consult chart page
5.
Before placing the material on the machine see that:
* The presser foot and needle clamp screws
are both tight.
* The sizes of the needle and thread suit the
kind of work to be done.
* The needle and take-up lever are at their
highest position.
* The tensions have been properly adjusted. *The ends of threads have been drawn
about 4 inches to the rear of the machine. * The feed dogs are up. * 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 position, 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 thread into the shuttle. See pages
34 & 35.
15
SETTING STITCH
LENGTH
Turn stitch length control knob to the desired point between 0 and 5. The red mark indicates the setting for a satin stitch. This will vary slightly depending upon the type of material to be sewn. The 5 setting is the longest stitch. The size of the stitch selected will depend on the fabric sewn.
REVERSE STITCHING
Push button when reverse stitching is required. Reverse stitching, often called back tacking is used for reinforcing and finishing all seams.
TURNINGA
CORNER
Stop sewing machine with needle in fabric. Raise presser foot. Turn fabric. Lower presser foot and continue stitching.
BASTING
For accomplishing quicker, more even and firmer basting, we suggest you regulate the machine in the following manner; Set stitch length at No. 5 for the longest possible stitch. Basting is easily removed by pulling bottom thread. When basting
very sheer fabrics, use a paper backing.
16
FASTENING
A
SEAM
Be sure both threads are drawn back under the presser foot. Lower needle into fabric about ½ inch from beginning of seam. Push button and stitch in
reverse until needle reaches beginning of seam. Release button and complete seam. When you reach the end, push button and sew back over ½ inch of completed seam.
ZIGZAGCONTROL
SETTINGSTITCHWIDTH
Insert disc No. 1A. Turn the stitch width control knob to the desired setting between 0 and 5 on the knob. Zigzag stitch width increases from 0 to 5. Straight stitching is possible with control on 0 setting or by removal of pattern disc. Be sure the dual purpose needle plate is set properly. (See page 11).
When sewing with the double needle the stitch width control
must not be advanced beyond 3_ setting.
INSERTINGPATTERNDiSC
1. Turn handwheel so that the needle is in its highest position.
2. Pull pattern disc shaft cover open.
3. Push cam follower release lever @ to the right and keep it there during insertion. See illustration 1.
4. Grasp pattern disc and slip disc onto the shaft. Make sure the retaining pin _) enters hole in disc.
5. To begin a pattern at a specific point each time, push the cam follower release lever to the right with one hand, depress the retaining pin. Turn the cam so that the white dot engraved on the disc is aligned with the point on the cam follower ©. See illustration 2. Shut cover.
6. To remove pattern disc, open cover and pull disc from the
shaft.
There are two different patterns on each disc. A picture of
each pattern is on the disc surface. Position disc into machine with desired pattern facing up.

DECORATIVESTITCHING
This machine enables you to sew beautiful decorative and embroidery stitches by means of various discs supplied with your machine. The movements of the needle are controlled by the disc. Basic decorative stitches are made with stitch width at 5 and stitch length at the red marking on the dial. The latter will vary slightly depending upon the type of material to he sewn. All patterns also can be made with double needle. See page 31. Pattern will be changed if using any other length or width. Decorative stitch No. 1A is generally referred to as the satin stitch.
It is necessary to reduce the top tension somewhat for decorative stitching. As the stitch width is increased, the tension should be decreased. This will prevent the material from
puckering and will prevent the bobbin thread from coming up on the top of the fabric.

DARNING st,,°h, dth o
Feed clog controJ Left
Remove presser foot. Stretch fabric between embroidery hoops and place under needle. Draw the bobbin thread up through fabric by holding the upper thread and taking one stitch at the spot where you wish to begin darning. Lower presser bar. Start sewing at a medium machine speed. Move the fabric back and forth with a steady
rhythm to cover the darning area. Then turn the fabric and sew another layer of stitching at right angles to the first. Move the fabric fast for long stitches, slowly for
short stitches.
If you wish to darn without using embroidery hoop, leave the presser foot attached, move feed dog control to the left, and push down outer ring of presser foot knob, thereby the pressure on the presser foot is released. Then proceed as above, stretching fabric tightly between hands.
BUTTONS d s:
Align two holes of button with slot of presser foot and lower foot to hold button securely. Drop feed dog.
Turn hand wheel by hand until needle point is just above button. Adjust stitch width so that needle will align with a hole of button. Turn hand wheel again by hand so that needle goes into second hole, readjust stitch width if necessary. Stitch a number of times, turning hand wheel manually. Finish with an extra 2
inches of thread, draw thread to reverse side and tie securely.
If using a 4 hole button repeat the above procedure. NOTE : To make a small thread shank when sewing
on a flat button, place a straight pin or needle between the holes of the button.

HINTSFORPERFECTBUTTONHOLES
Mark the position of each buttonhole on the garment with chalk or a line of basting.
Loosely woven fabrics and fabrics that stretch easily such as jersey should have an inter- facing of a firm fabric. Use
cambric or taffeta between woolens and rayons-organdy
or lawn between light weight
and sheer fabrics.
Use buttonhole scissors or buttonhole cutter to cut buttonhole open.
Always make a practice buttonhole on a piece of the
fabric to be used in the garment.
A wider stitch width may be desirable on heavy weight
fabrics.

GATHERING
Attach gathering foot. (See page ll). Set machine for straight stitching and test gathers on a scrap of the same fabric yon
plan to use. Fullness will depend largely on thread tension and length of stitch. For slight fullness, tighten thread tension and set stitch length for ordinary sewing. For greater fullness, lengthen stitch and keep tight thread tension. Fullness will vary
with different fabrics.

SETTINGTHEDOUBLENEEDLE
Raise the needle bar to its highest position and loosen needle clamp screw. Hold double needle assembly with flat side away from you. Slip the needle as far as it will go into needle clamp, and tighten the screw.
THREADINGTHEDOUBLENEEDLE
Place a spool of thread on each spool pin. Draw both threads
through upper thread guides. Pass a thread between each set of tension discs of the thread tension assembly. Continue
threading as you would for single needle sewing except where double thread guides are provided. Draw one thread through each side of the double thread guides and through each needle from front to back. Pull several inches of thread through.
(See illustrations]. Thread bobbin and pick up bobbin thread as for single needle sewing.
THREADSELECTION
Use only mercerized sewing thread size 50 or finer. The same size thread is recommended for both upper and lower thread-
ing.
30
DOUBLENEEDLE
STITCHING
All decorative patterns are possible with double needle. Before starting any stitching operation, check needle drop by turning the handwheel manually. Needle should enter fabric without touching the presser foot or needle plate. The stitch width control must not be advanced beyond 3½ setting.
TURNINGA CORNER
To turn a square corner when stitching with a double needle, stop stitching with the longer needle
tip just piercing the fabric. Raise the presser foot, shift fabric half the turn, lower presser foot and take one stitch. Raise the presser foot again,
complete the turn, and begin stitching in the new direction.

SYNTHETICS
Your KENMORE will sew alt the new fabrics of synthetic fiber, such as nylon, *Orlon, **Dacron, rayon, acetate, blends of these, and combinations of synthetic and natural fibers. When stitching a fabric of blended or combined fibers, handle it as you would a material of the fiber present in the largest percentage. For example, a fabric woven of 60fb Orlon and 40_3 silk should be handled as one made entirely of Orlon.
When stitching a fabric that is over 50,¢6 synthetic fiber, remember:
a. Select patterns of the loose fitting type with cap or kimono
sleeves, because most synthetic fiber fabrics cannot be eased
with steam pressing, and are not absorbent.
b. Use a synthetic thread. c. Use a fine needle as recommended in chart on page 5.
d. Wind the bobbin in the usual way, but do not pass thread
between tension discs. Guide thread by hand for a smoothly
wound bobbin. e. Choose the stitch length that gives the most satisfactory seam. f. Check thread tensions by sewing on a double thickness of the
fabric to be used. Usually the upper thread tension must be
loosened. Sometimes both bobbin and upper thread tensions must be loosened (Pages 12, 13).
SEWINGONPLASTICFILMS
Set the machine with normal thread tensions and a large size stitch. Use a fine needle and mercerized thread. Hold plastic pieces together with cellophane tape or paper clips rather than pins. Sew corners slightly rounded rather than square.
