bed.

2. Raise hinge pins in the cabinet or case. Slip machine head onto pins.

3. Tighten hinge screws securely.

4. Push the speed control plug onto

three-prong connector under the bed plate. Lower machine head to

front cabinet flap.

Plug machine cord into any 110-120 volt wall outlet. Turn on power by pushing light and power switch.

Spool pins are packed in accessory box. Screw thread spool pins in place securely with a screw driver.

Position nylon discs as shown in illustration.

CONVERTING TO FREE-ARNI SEWING

Base Release Button Fig. 1

1. Remove the base from the machine 2. To replace the base, simply slide it by pushing the release button (if applicable) and pulling the base to the left. (Fig. 1, 2)

along the free arm to its original position. (Fig. 1)

Note: Base cannot be removed or

replaced unless shuttle cover is closed.

WINDING THE BOBBIN

1. Release clutch by pulling hand wheel or turning clutch knob toward you as shown in Fig. 1.

2. Draw thread from spool through bobbin winder tension disc as shown.

3. Pull end of thread through hole in bobbin as shown.

4. Place bobbin onto bobbin winder shaft with end of thread coming from the top of the bobbin. Push

bobbin winder latch against bobbin until It clicks. Holding onto end of thread, start machine. When bobbin is slightly filled, snip off end of thread.

5. Start machine. Wind thread until bobbin winder latch releases.

6. Push in hand wheel or tighten clutch knob to return to stitching position. Remove bobbin.

THREADING THE BOBBIN CASE

1. Remove base front coyer by push ing the release button on the left

side. Open the shuttle cover.

end of the thread between the tension discs as shown. Pull the spring wire

loop up and past the top hook until

the thread can be slipped into hook

(See Fig. 2). When the thread is released, the spring wire loop will return to position (Fig.

Fig. 1,

ADJUSTING TOP TENSIONS

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 as shown below. Use the straight stitch function.

A perfect straight stitch wilt have threads locked between the two layers of fabric with no loops on top or bottom.

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.

CHECKING TENSIONS

The easiest way to check tensions is to sew a medium zig zag stitch on the fabric you will be using. Use the appropriate type of thread and needle.

Use different colors of thread on the bobbin and upper spool.

Sew a line of zig zag stitches. The bobbin thread should not show on the

top of the fabric.

Adjust the top tension if necessary to achieve the stitch balance mentioned

above.

STITCH WIDTH CONTROL

This control regulates the width of the

stitch you select THE HIGHER THE

NUMBER‘THE WIDER THE STITCH.

You may vary your zigzag stitch width

by adjusting this control to the setting

you desire.

This control must be on Red Dot in

order to do straight stitching. Turn only the outer rim of this control to set the stitch width. The center of the control

dials the special stitches the machine is

capable of sewing.

STITCH LENGTH CONTROL

The stitch length control regulates the

length of the stitch you select. THE

HIGHER THE NUMBER-THE SHORTER

THE STITCH.

The number on stitch length control

indicates the approximate number of

stitches per inch. The stitch setting you

use will be determined by the thickness

of the fabric you are sewing.

A lounger stitch setting should be used

for thicker fabric or more layers of fabric.

The middle range of the control is the 10-12 stitch per inch range which is the most commonly used.

A basting stitch is made by using the longest possible stitch setting-6 stitches per inch. The red marking on the control is the setting used for the shortest stitches such as in Satin Stitching.

REVERSE STITCH CONTROL

It is best to begin and end seams with a few stitches taken in reverse. This is called back tacking. Back tacking fastens the ends of the searns firmly and prevents raveling. ^ j

When reverse stitching is needed, turn the control clockyyise and hold there gyring sevying. The fabric will imme diately start feeding backwards and seam will be fastened.

SPECIAL STITCH MODIFIER

This control gives you the means of varying the stitches on the Special

Stitch Diak When the pointer is turned

to the Red Dot, the machine sews forward only, vyhen the ppinter is

turned to the White Dot, the forward

designs are varied by the machine

sewing in a forward and reverse manner. Carefully read directions given In the next section 6f the book in order to accomplish the various stitches correctly.
