NEEDLE, THREAD AND FABRIC CHART
Your fabric will determine the choice of needle and thread. The following table is a practical
guide to needle and thread selection. Always refer to it before a new sewing project. And be
sure to use the same size and type of thread in the bobbin as in the top thread supply.
Flat side
Needle
Pin
Flat side toward the back
Always disconnect the machine
from power supply by removing
the plug from the wall-outlet.
CAUTION
CHANGING THE NEEDLE
1. Raise the needle bar to its highest position by
turning the hand wheel toward you.
2. Loosen the needle clamp screw by turning it
toward you.
3. Remove the needle by pulling it downward.
4. Insert the new needle into the needle clamp with
the at side toward the back.
5. Push the needle up as far as it can go.
6. Tighten the needle clamp screw with the screw
driver.
NOTE: Tighten snugly, but do not over tighten.
Helpful Hint: Placing a scrap of fabric under the presser
foot and lowering the presser foot makes it easier to change
the needle and will preclude dropping the needle into the
needle plate slot.
Change the needle often. As a general rule,
needles, should be changed every 6-8 hours
of actual stitching time.
