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.
