Place fabric under foot about 1 cm (0.4") inside the edge. Lower presser foot lifter.
Important:
Hold on both threads during the sewing of
the first 3—4 stitches of the seam.

(2) Double presser foot lifter

In order to obtain wider gap when using very thick materials, firmly push presser foot lifter up as far as it will go.
To reinforce seam, sew backwards to the edge of fabric by pushing down reverse sewing lever.
Release lever and commence forward sewing guiding fabric by hand as it is fed.
Never pull material.

(4) Cloth guide

Use doth guide when sewing a long seam of regular distance from edge of material. Set guide in hole on arm, at right of needle plate, and adjust distance. Run machine with edge of fabric touching guide. Position cloth guide at an angle to sew a curved seam.
Sew reverse stitches for reinforcement at end of seam.

^
Test stitch performance on a scrap of material you are going to use. With correct tension ((a)), upper and lower threads tension is equal and strong enough to lock both threads in center.
If upper tension is too tight (loose), upper (lower) thread lies straight along upper (lower) surface of fabric ((B).(c)). Correct by turning tension dial.

5. ZIGZAG STITCH SEWING

Set machine as shown. To prevent seam ends unravelling, set machine
for straight stitch and sew in reverse at
beginning and ending of seam.

(1) Zigzag width control

Set control at required number. Larger the number, wider the stitch. Set it at 0 for straight sewing.
Make sure needle is in upper position when you set control.

(2) Needle position control

Needle position can be changed by turning needle position control.
When selecting position, make sure needle is in upper position to avoid tearing material or bending needle.

(3) Thread tension for zigzag stitch

Better-looking zigzag stitching requires less upper tension than straight stitching. Loosen upper tension slightly.

and add 0.3cm (1/8") for bar tacks.
Mark buttonhole size on material.

(3) Determine width

Determine width according to diameter of button, its thickness, and kind of material.
Completely push back sliding part @ of buttonhole foot. Place .materia! under foot so that marking of buttonhole passes through center of foot and

Remember the point where arrow shows so that it is not necessary to mark end lines for all buttonholes.
Bar tacking: Change pattern to 3
and
sew 5-6 stitches.
Right side: Change pattern to 4 ([(“) and sew right side until it catches first bar tack.
Quick finish: To prevent unstitching, set zigzag
width at 0 and proceed for a few stitches.

(5) Cutting buttonholes

Stick a needle through bar tacks to prevent over-cutting.
Cut buttonhole along center with buttonhole cutter.

(6) Corded buttonholes

For stretch fabrics such as knits, a corded buttonhole is effective to keep finished buttonhole in shape.
Hook filler cord on top spur and lead ends of cord under foot, pull taut, and hook them to bottom notches as shown.
Proceed with stitching as for regular buttonholes.
When buttonhole is completed, pull filler cord
ends so that loop on the other end disappears
into buttonhole stitching. Thread ends of cord to reverse side and tie, or cut both ends of cord.

Overlooking stitches make it possible to sew and overcast seams at the same time.
Set machine as shown.
(a) For medium, thin material (b) For medium, thick material
Put two pieces of cloth together with right
sides facing and sew. To prevent edges from fraying, sew so that
right side stitches drop outside the edge of material.
In some cases overlooking stitches can be used
for overcasting.

^4. APPLICATIONS OF THE ELAS
TIC OVERLOCKSTITCH
This stitch is very effective for overcasting, édgestitching, etc, on knits and very stretchy fabrics, also, for decoration.
TOPSTITCHING
A decorative topstitch can be produced with the elastic edging stitch. Stitch around the
structural lines of the garments for a dramatic effect. Topstitch a braid or decorative inset with the elastic edging to add an additional decorative flair. Pattern: AA
Length: 5
Width: 5
Feed Dog: Up
Pressure: Normal
Foot: Embroidery
Needle Position: L or R
EDGING
As with the stretch blind hem, the elastic edging stitch can be used for a decorative edge on place mats, napkins and tablecloths. Proceed as you would with the stretch blind hem stitch, but use the elastic edging stitch instead.
Pattern: AA Length: 5
Width: 3-5

15. APPLICATION OF RICK-RACK
A. Topstitching/Rick-Rack A decorative topstitch can be produced with the rick-rack stitch. Stitch around the struct ural lines of the garment tor a special effect. Topstitch braid or a decorative inset to add an additional creative flair.
B. Tapering/Rick-Rack The rick-rack stitch may be tapered to form creative stems and petals of flowers, embro
idered pictures and wall hangings. As in tapering the zigzag, slowly turn the stitch
width lever from 0 to 5 and back to 0. A
group of these tapered rick-rack stitch will
form bouquet-like effect.
C. Procedure:
• The elastic rick-rack stitch is a zigzag line of stitching that is desired so that seams
may be pressed open.
■ Apply this stitch to areas of stress on both wovens and knits.
• Use narrow width of zigzag as a heavy duty triple stitch for seams.
• Use medium and wide widths of zigzag for
overcasting edges of seams, facings and hems of heavier weight fabrics such as terrycloth, and for attaching elastic. Use also for decorative stitching.
• Guide your fabric from the front. Do not pull or push as it will cause poor stitching.
Page 31
STHETCH SEAMS
A ball-point needle is essential.
Paper may be laid under knits for smoother
feeding. (a) Medium-weight fabrics-
double knit jersey. Apply elastic triple stitch.
(g) Light-weight fabrics
Apply small zigzag. Reduce upper and lower thread tension.
© For Very elastic fabrics-
spandex (power net)
Use lapped or abutted seam.
Apply multiple zigzag.

25. THICK CLOTH SEWING

(particularly denim)
For thick fabric sevv'ing, it is' important to respect scheme.
You remark that the sewing is set flat. Needle
is perpendicular on the seam and penetrates cloth properly.
Improper setting causes slips and break of
needle. For sewing of importât thick cloth,
sew gently maintaining the cloth perfectly.
Breaking needle is not mechanical problem but simply misuse.

i6. TWIN NEEDLE THREADING
Thread in the same way as normal threading, except at points (D, (|) and ©.
At point®, pass threads separatly to right and left of tension disc.
At guide®, pass one of threads to right guide and the other at left guide.
At point®, thread from right guide should be lead to right needle eye, and from left guide to left needle eye.

When using twin needle sewing be sure zigzag width control setting between 0 and 2.5, and
needle position control at r~Tl . If zigzag width control above 2.5 or needle position control at (« ) , ( 5) this will cause needle break.

27. NEEDLE CHANGING-AND SETTING
Set needle in the highest position by turning handwheel towards you.
Loosen needle clamp screw and remove
needle.
With flat face away from you, insert a new
needle into groove of needle bar. Push needle until it reaches stopper @ and
tighten needle clamp screw firmly.
Always use a straight needle with a sharp point.
Using defective or worn needles not only causes stitch skipping, breakage of needles or snapping of thread; it also can damage hook and needle plate.
