Operating Instructions:
The symbol “0” of a switch indicates the “off ” position
of a switch.
“For appliances with a polarized plug (one blade wider
than the other ).
To reduce the risk of electric shock, this plug is intended
to fit in a polarized outlet only one way. If the plug does
not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to install the
proper outlet. Do not modify the plug in any way.”

sewing. Reduce the pressure to “ 2 ” for appliqué, cut
work, drawn work, basting and embroidery.
Set the pressure to “ 1 ” when sewing chiffon, lace,
organdy and other fine fabrics. Velours and knits with
a lot of stretch may also require a “ 1 ” setting.

Selecting Needle and Thread
For general sewing use needle size 11 or 14. A fine thread and needle should be used for sewing lightweight
fabrics, so the fabric will not be marred. Heavy fabrics require a needle large enough to pierce the fabric
without fraying the needle thread.
In the needle case you will find Two size 14s, two size 11s and one blue tipped needle. Use a blue tipped needle
to eliminate skipped stitches when sewing knits and synthetic fabrics.
There are also specialty needles available from your sewing machine dealer. A denim needle with a sharp tip is used
to effectively pierce dense fabrics such as denim and canvas. For topstitching, a special topstitching needle with a
larger eye accommodates heavier weight thread. Leather needles punch small holes in leather and suede allowing
the thread to follow through the hole.
Check your needles frequently for rough or blunt tips. Snags and runs in knits, fine silks and silk-like fabrics are
permanent and are often caused by damaged needles.
Always purchase a good quality thread. It should be strong, smooth and consistent in thickness.
