_The sizes of needle and thread suit the
kind of work _o be done.
_The needle and take-up lever are at their
highest position,
* The ends of the threads have been drawn
about 4 inches to the rear of the machine
• The feed dogs are up.
Place material under the presser foot. insert
the needle into the material by turning the
hand wheel toward yon, lower presser foot
and start sewing. Experiment by sewing +mthe fabric to be used to determine tension
adjustmenl and correct stitch settings.
To remove the work, first turn hand wheel
toward you nntll needle is at its highest
position1, then raise the presser _oot+ draw
material to the rear and cut off excess
thread with the thread cutter Iocated on
the presser bar, To avoid sewing off the
end of the material, hack tack each seam.
See page i1.
IMPORTANT : Always turn the hand wheel
toward you! When machine is not being
used, pIace a piece of material o_er tile feed
dog and lower the presser foot, Always
have fabric under the presser loot when
operating the machine. Operating thread

This mactline enables you to sew bea_,tifut decorative and embroidery stitches by means of
various discs supplied wlth your machine. The movements o[ the needle are automatically
eontro|led by the disc. Basic decorative stitches are made with stitch width at 4 and stitch
Iength at the red mark opposite S, The latter will vary slightly depending upon the type
o[ material to be sewn. Pattern will bc changed if using any other length or width. All
patterns also can be made with double needle. Sec page 25.

WITHPRESSERFOOT'
1. Turn [eed dog control to right.
2. Press down outer ring of presser loot knob. see page 10. With presser foot knobin this position, mending, darning, monogram work. etc, may be done.
3. Stretch fabric tightly between two spring cmbrnidery hoops and place underneedle,
4. Lower presser bar so thread will have some tension. "When you start to darn,move fabric back and forth to cover darning area. Then turn fabric and continuesewing at right angles to the previous stitching. Use medium machine speed. Youcan make any length stitches desired. Slow movement of fabric wilt make shortdarning stitches. Fast movement will make long stitches.
5= When you finish darning, raise presser foot m_d remove fabric, Increase pressurefor general sewing by pressing down tuner pin of the presser foot knob. Turnfeed dog c(mtroI to left.
WITHOUTPRESSERFOOT'
1. Turn feed dog control to right,
2. Remove presser foot.Proceed as directed under steps 3 and 4 above,

knob is turned, while sewing, the more stitches are formed,
Reproduction on identical size bt,_onholes is facilitated with the aid oithe graduations on the left side oi the bt_ttonhole foot. These graduationnare 1 8 inch apart. Just mark the starting points ot the buttonholes, letthe needle pierce the fabric and set the index nlark A on the upperportion of the foot at the same graduation mark B as it was set for the[irsi buttonholc_ Lower the foot.

ADJUSTING YOUR SEWING MACHINE FOP. 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. Chcck threading carefully. See page 9.4. Check the thread tension balance. Use mercerized thread, and a correct size needle
[or the fabric you are using. Do not try this test with synthetic thread as it willnot break.
Begin with a full bobbin, properly threaded into tl_o case. Set the stitch length atabout I2 stitches per inch. Fold a 6" ,square o_ your fabric in half diagonally,forming a triangle. Make a line of stitching ½- from fold.
a. I[ scum is puckered-both tensions arc too tight.
b, If bottom thread is looped-tighten upper thread tension, and repeat test.
c. If top thread lays on top o[ fabric-loosen upper thread tension, and repeattest.
Grasp the stitching and pull with a snap _o 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
S alrle snap.
Bobbin tension may also bc reset by this procedure. Start with a loose bobbin threadtension, Tighten the spring se_ ew gradually until bobbin case and full bobbin can bcgently lifted from your hand by the end of the bobbin thread.
