ADJUSTING THE TENSIONS
A correct stitch can be obtained by varying the tension on the
needle thread. To adjust the tension of the needle thread, Lower
the pressure foot.
Adjust the tension regulator as the case demand, by reffernng
to iUustration. (Fig.ll) The quality of sewing depends on the tension of thread. Therefore, it is necessary for the user to
become fully familiar with the correct tensions through practice.
Before adjusting lower tension be sure that the machme is
threaded properly. When necessary to change the bobbm te^n,
turn small screw (Fig. 12) on side of the bobbin case clockwise to tighten, counter-clockwise to loosen.
When the upper and lower tensions are properly balanced,
perfect stitch will be formed with both threads interlocking in
fabric (Fig. 13). , , . n j

ADJUSTING PRESSURE AND FEEDING
OF FABRIC
GENERAL SEWING. For normal straight stich and zigzag
stitching, the pressure bar cap or darner release, Fig. 17 and
18 is at its lowest position and the drop feed dial Fig. 16 is
set to "UP" position.

SEWING THIN OR LIGHT WEIGHT FABRICS

When lighter pressure is required to sew satisfactorily on thin silk or filmy material, the pressure cap should be about halfway down.
Release all the way by pressing the snap look, C®, Fig. 17) and then press cap C®, Fig. 18) down again to halfway spot.

DARNING AND MONOGRAMMING

In order to move the fabric freely in any direction for darning, mending and certain kinds of free-hand embroidery, release the cap C®, Fig, 18) completely by pressing down on the snap lock,
C®, Fig. 17). Set the drop feed dial (Fig.l6) to "DOWN." which drops the feed well below the needle plate. To return feed to normal, set to "UP", push cap down (Fig. 18).

SEWING ON BUTTONS

1. Use button sewing foot and zigzag needle plate.
2. Set drop feed dial to "EXDWN" position.
3. Set the needle positioning lever to "L" position.
4. Move zigzag width control dial to "0" position. Place the button so that its left hole comes directly under the needle, then gently lower the presser foot. Move the zigzag width control dial to the right until the needle comes exactly over the right hole of the button. Turn the hand wheel slowly by hand to be sure the needle
clears both holes of the button.
5. When needle goes into the center of each hole, run the machine at medium speed, making five or six stitches, stopping with the
needle in the left hole.
6. To lock the zigzag stitch and prevent ravelling, set the zigzag width control dial at 0, and take a few stitches in the same
hole. If you wish, you may place a roimded toothpick over the button between the two holes, and sew button to fabric in regular way. Remove the toothpick and wind thread under
button, forming a shank. Fasten. , If a four hole button is to be sewn, follow the same procedure as above for the two hole button. Now lift pressure foot slightly
and move fabric to permit stitching the remaining two holes.
Hooks, snaj», etc. are sewn to the fabric with the same proce
dure as for sewing two hole buttons.

MAKING BUTTONHOLES

A buttonhole can be made in any length within the range of
limited width.
1. Use special purpose buttonhole foot (Fig. 23) an igzag needle plate.
2. Mark the beginning and end of the buttonhole on fabric with a
basting line or tailor's chalk. Make one on scrap fabric followmg directions below to be sure machine adjustments are correct.

8. Slit the buttonhole between the two rows of stitching with the buttonhole cutter or seam ripper. Be careful not to cut
the stitching or the bar tacks.
If you plan to make buttonholes on sheer or soft material, place tarlatan or paper, which can be torn away after
stitching under the fabric.
NOTE; When the left side pitch is different from the right side
pitch, adjust the pitch by means of the stitch length control, so that pitches on both sides will be the same.

EMBROIDERING WITH A HOOP

^ It is easy to follow a stamped design or to work free hand when embroidering or monogramming. Release the pressure from the foot by pressing down the snap lock on the darner. Drop feed dial to "DOWN" position. Then hang the
upper end of the embroidery spring on the needle clamp. (See Fig. 25).
Stretch the fabric in an embroidery hoop, and place under
the needle after removing the pressure foot. Set the zigzag width at the size you prefer and lower the pressure bar lifter. Then operate the machine at a rather high speed while moving the hoop slowly with both hands. Work carefully and be sure to
keep fingers out of the needle.
FOR BEST RESULT A WOODEN HOOP WITH TENSION
ADJUSTMENT IS RECOMMENDED"

THE ADJUSTABLE CORDING AND ZIPPER FOOT

This attachment is used to make and insert covered cording, and to sew in zippers. Loosen thumb screw (Fig. 26) to slide foot to either right or left of needle.
CORDING. Fold bias strip of fabric over cord. Loosen thumb screw and set foot so needle is centered in needle hole. Machine
baste cord in place (Fig. 27. ).
To sew covered cord to material, reset adjustable foot so
needle stitches closer to cord and on edge of base fabric.

SEWING IN ZIPPER

Loosen thumb screw and slide foot so needle enters center of
needle hole. Guide metal of zipper along edge of foot (Fig. 28).
17
Fig. 28
Stitching should be close to zipper to allow easy opening and
closing. Adjust to sew from either right or left side, whichever is more convenient.

NARROW HEMMER

With the needle at its highest position, replace regular presser foot with narrow hemmer (Fig. 29) For a plain narrow hem, make a 1/8 inch double fold for about two inches along edge of fabric. Hold each end of the two
inch fold, slip undereneath hemmer. Bring fold up into the scroll of hemmer, draw forward to end and fasten with
point of needle. Lower presser bar lifter. Gently pull ends
of thread as you start stitching.
Guide material slightly to right, and it will take a
double turn through scroll.
Trimmed Hem To sew a narrow hem and attach
lace in one stitching, insert lace in the slot next to needle
(Fig. 30). Sew hem as above, guiding lace under needle
and hem into scroll.
Lace Edge with Invisible Stitching Hold lace 1/8 inch from raw edge on right side of fabric. Insert both inscroll as for plain narrow hem (Fig.31). Let hem roll over and
sew in lace, press lace out flat along edge with hem turned up.
It is possidle to have a little fullness in lace by feeding
it freely under scroll.
French Seam With right sides together, place top piece
of material 1/8 inch inside edge of lower piece.
Insert in hemmer scroll, allowing hem to roll over and
sew in too fabric, makincr French seam.
Fig. 29
Fig. 30

QUILTING GUIDE

Tlus guide for making parallel rows of stltcliing is attached by placing the pronged holder between the pressure foot and the pressure foot clamp screw (Fig. 32). Adjust the curved bar to press lightly on the fabric. By letting the guide ride on the first stitching line, successive rows will be an
equal distance apart. When the bar is attached so that the curved part is to the right of the needle, it may also serve as a seam width guide.

SEAM GAUGE OR CLOTH GUIDE

Ig

difficulties occur they can be remedied with minor adjustments. Upper Thread Breaks
Be sure needle is inserted properly. Check on correct way to thread machine. Use correct needle size for thread.
Do not have upper tension too tight.
Lower Thread Breaks-------------
Check correct method of threading bobbin case.
Be sure lower tension is not too tight.
Needle Breaks
Do not tug or pull on the fabric while sewing as this will bend and eventually break the needle. Be sure pressure foot is firmly attached to bar.
Skipped Stitches
Do not use a blunt or bent needle. Insert needle correctly. Use correct needle size for thread. Be sure pressure on foot is sufficient when sewing heavy fabrics.
Stitches Loop
Make sure tetiginug are properly balanced and that machine is threaded, correctly.
Machine Binds------------
Clean thread, dust and lint from body, shuttle and rece.
If condition ontinues, it may be that the machine is gummy with oil. Apply kerosene to oil holes, run rapidly for a while, and wipe dry. Then lubricate again with fine sewing machine oil.
