TENSION TEST
To verify that the machine is threaded properly in the tension discs, do this simple check:
1. With the presser foot raised and the needle unthreaded, pull the thread. You should
detect only a slight resistance and little or no deflection of the needle.
2. Now lower the presser foot and again pull the thread toward the back of the
machine. This time you should detect a considerable amount of resistance and much
more deflection of the needle. If you do not detect the resistance, this means you
have not threaded the upper machine tension correctly and need to rethread it.
REVERSE SEWING / CUTTING THE THREAD
1.
Reverse sewing is usually done at the beginning and end of a seam. The
purpose Is to lock the threads at both ends of the seam so that the seam does
not unravel.
2.
Set the machine for straight stitch sewing, depending on the fabric you are
sewing.
3.
Place the fabric under the presser foot, just inside the top raw edges of the
fabric.
4.
Lower the presser foot and sew about 3 stitches.
5.
NOTE: The length of the stitch when sewing in reverse Is pre-set, regardless of the
selected stitch.
6.
Stop sewing, then press and hold the Reverse Lever, located on the front of the
machine.
7.
Hold it while you sew 3 stitches In reverse.
8.
Release the lever and sew forward again, until you come to the opposite end of
the fabric.
9.
Press and hold the Reverse Lever to sew in reverse again for about 3 stitches.
10. Release the lever to sew forward again to the end of the fabric.
11. Lift the presser foot lifter, then remove the work from the machine.
