Below are a few details included:
ADJUSTING YOUR SEWING MACHINE FOR 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 the chart on page 5 for needle size.
2. The upper and bobbin thread should be the same thread.
3. Check threading carefully. See page 8-9.
4. Check the thread tension balance.
Recommend mercerized thread and a correct size needle for the fabric you are using: Do not try to test with synthetic thread as it will not break. Begin with a
full bobbin, properly threaded into the case. Set the stitch length at about 12 stitches perinch. Fold a 6-inch square of your fabric in half diagonally, forming a triangle. Make a line of stitching ½” from the fold.
Check to see if any of the following:
a. The seam is puckered – then both tensions are too tight.
b. Bottom thread is looped – tighten upper thread tension, and repeat test.
c. When top thread lays on top of fabric-loosen upper thread tension, repeat the test. Grasp the stitching and pull evenly and firmly until one or both threads break.
a. Both threads break – tensions are balanced.
b. When 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 same snap.
