CONTROLS

TOP TENSION CONTROL

t

_,__i_i __,__i,.,i:__i!,ii. i!i. i-_!_!iii_,

Probably the most important control on your machine is this one that regulates your top thread tension. It consists of discs between which the thread passes. The pressure on these discs is regulated by turning the dial. The higher the number, the tighter the tension.

There are many reasons for having to reset your tension. The best tension for one fabric may not be correct for another. The required tension depends upon the stiffness of the fabric, thickness of the fabric, numbers of layers of fabric being sewn, as well as the type of stitch you are making.

It is best to test the stitching on a scrap of the fabric you are using before starting to make a garment. To adjust for the correct stitch; see next page.

ADJUSTING TOP TENSIONS

O Upper thread too tight

Decrease Tension

0 Upper thread too loose

Increase Tension

ADJUSTING BOBBIN TENSIONS

Bobbin tension requires adjusting less frequently than the upper thread tension.

If the stitch is satisfactory but the seam is puckered, it may be necessary to loosen the tension on both the top and bottom threads. Be sure to balance them as indicated on page 10.

When adjusting the tension on the bobbin case, make slight adjustments with a screwdriver. CorreCt tensions will produce the stitch shown on page 10.

OTHER ADJUSTMENTS OF MACHINE IN SEWING

In addition to the obvious controls of your machine there are other small regulators and controls to aid you in using your sewing machine.

PRESSER FOOT PRESSURE REGULATOR

Push down outer ring of presser foot pressure regulator (See above illustration). 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 all the way down.

Insufficient pressure may cause poor feeding of the fabric, skipped stitches, or difficulty in guiding the fabric.

When sewing multiple thickness or heavy fabric reduce the pressure. Increase pressure when sewing lighter weight fabrics. If feed dog or presser foot marks appear on the fabric, reduce the pressure.

FEED DOG CONTROL

The feed dog control is located on the right front of the machine bedplate. There are a few times when you want to control the feeding of the fabric yourself. When the control is set to the left, the feed dogs drop and do not move the fabric.

For most of your sewing the feed dog control is turned to "U". (Feed dog up)

Fig. 1

SEWING LIGHT

The light and power switch shown at left provides the electric current for the motor as well as the light. In order to operate the machine, this switch must be on.

To turn on the light, depress the switch. If you are interrupted while sewing and must leave the machine unattended, just turn off the switch and the machine cannot be started accidentally.

The sewing light is located inside the face cover plate as shown. To replace the bulb, push switch to off, unplug machine and swing the face cover plate open. Push up on the bulb slightly and turn bulb to the left. Remove bulb from socket. Push in new bulb and turn to the right.

Fig. 2

SEAM GUIDES

Seam guides are printed on either side

of the needle plate to aid you in guiding your fabric. THE GUIDE LINE

EXTENDING ABOVE THE RIGHT SIDE

OF THE NEEDLE PLATE IS THE "ALL

IMPORTANT" 5/8" SEAM LINE.

_ i ?? _r ,

PRESSER FOOT LEVER

To aid you in the placement of heavy fabrics under the presser foot, the lever can raise foot beyond the normal "up" position. This is also an aid in changing your presser feet.

PRESSER FEET

The various presser feet that come with your Kenmore Sewing Machine are designed to help you to do every kind of sewing easily and perfectly.

To change the presser foot:

1.Raise the needle to its highest position by turning hand wheel towards you.

2.Raise the presser bar to its highest position by lifting the presser foot

???lever.

3.Loosen the presser foot screw. (You do not need to remove the screw)

4.Choose the proper foot. Insert from the front.

5.Tighten the screw using the large screwdriver to make certain the foot is secure.

C

feet:

Now that you are familiar with the controls on your machine and with the accessories provided for the machine, you are ready to start to sew with your new Kenmore sewing machine. Below are some good habits to follow each time you sit down to sew:

. Check the needle-it should be straight, properly set and sharp on the point.

It should b_ the correct size for the fabric and thread being used. Change your needle frequently. Many of the new fabrics made of synthetic blends tend to dull the needles more easily than fabrics made of natural fibers.

. Before placing the material on the machine, see that the ends of the threads have been drawn about 4 inches to the rear of the machine. Hold on to threads during the sewing of the first 3 or 4 stitches of the seam.

. Test the machine stitch on a scrap of fabric you plan to use. The fabric should be double thickness. Adjust the machine for the length of stitch and tension suitable to your fabric.

oFabric should be placed under the presser foot with the bulk of the material to the left of the needle and the right edge of the material placed on the 5/8" seam marking on the needle plate when making a simple seam.

5.Run the machine at a slow even speed. The more pressure you put on the speed control, the faster the machine will sew.

6.Fasten each seam by back tacking at the beginning and end of the seam.

7.Always finish sewing each seam with the needle at its highest point.

8.Guide the fabric gently with your hand in front of the needle. Never pull or hold the fabric in such a way that the normal feeding is altered.

9.When turning the hand wheel manually, always turn it toward you.

Set your machine just as shown in the

.illustration in order to straight stitch. It is important that each dial have the above setting. Before setting turn hand wheel toward you, so that needle is above fabric.

You will find in garment construction that you are doing two types of sewing- temporary and permanent.

??Temporary stitching-Usually the longest stitch possible and often done on a single layer of fabric. The various types of temporary stitching are:

Basting

Stay stitching

Guide line marking

,Permanent stitching-This is the actual stitching that holds the garment together.

Much of this stitching is visible on the outside of the garment and therefore must be good looking.

The best length stitch to use for medium weight fabrics is 10-12 stitches per inch.

This is in the middle range of the Stitch Length Control.

???:' ???_ _ ,!i ???i :i_ ???rr ???'

You must remember to lengthen the stitch for heavier fabrics, multiple layers of fabric and thicker seams. Some of these seams are:

Common two layer seams

Curved two layer seams

Top stitched three, layer seams

Top stitched four layer seams

When you have two seams crossing each other with considerable thickness, sew slowly and carefully so the seam will be as strong as possible in this area.

FASTENING A SEAM (Backtacking)

Be sure both threads are drawn back under the presser foot. Lower needle into fabric about ?? inch from beginning

of seam. Raise the Stitch Length Control to R and stitch in reverse until

needle reaches beginning of seam. Lower the control to again stitch forwards and complete seam. When you reach the end, raise the control and sew back over ?? inch of completed seam.

illustration for the simple zigzag. Follow

directions given below and in the

following pages for more specific uses.

OVERCASTING

Fig. 1

This is one of the more frequently used zigzag stitches in garment construction.

You may want to overcast along the raw edge of each seam allowance or fold the

raw edge toward the garment and stitch.

Fig. 1 shows the raw edge finished.

Fig. 2 illustrates the folded edge stitch- ed.

Stitch so the needle pierces the fabric

just short of the outside edge. Raw or

worn edges of older garments can be

overcast to prevent further raveling.

Satin Stitch Foot

Closely spaced zigzag stitches are called satin stitches. This is an attractive stitch used for appliqueing, monogramming, buttonhole making.

Whenever you are using this stitch, it is well to remember to loosen the'tension of

the top thread slightly. The wider the stitch you make, the Iooserthe tension should be.

If you are stitching on a very soft fabric, it is well to use,a backing of tissue paper or interfacing for a well formed stitch. Puckering of the material will be eliminated and the bobbin thread will not be visible on the right side of the fabric.

As with all special stitches, it is best to make a sample design on your fabric before starting the design on the garment.

New fabrics are coming on the market all the time. Remember that soft fabrics may need to be stabilized a little. This is especially true when buttonholing, monogramming, or design sewing as the stitches are so close together. A backing of tissue paper or interfacting may assist you in your sewing. The paper may be torn away and the interfacing cut away after sewing. Check your fabric by making samples of the designs, monograms, or buttonholes on a scrap of fabric before sewing on your garment.
