BERNINA
Overlocker Workbook 1
Fabric:
Firm fabric, 6" x 6"
Needle:
80/12 Universal
Thread:
4 cones of overlocker thread (blue, red, green, yel-
low)
Presser Foot:
Standard
Stitch:
4-thread overlock
Thread the overlocker for a 4-thread overlock stitch using thread
colors to match the color-coded threading path on the overlocker.
Adjust all thread tension settings as indicated below.
Stitch a 2"-3" thread chain without fabric.
Fold fabric in half to 3" x "6" and place under the presser foot.
Take 2-3 stitches on the fabric. Lower the needles into the fabric.
Raise the presser foot and with your left hand gently pull the thread
chain around the needles to the knife.
Lower the presser foot and continue stitching (cutting off the excess
thread chain) until you are one stitch off the end of the fabric.
Locate the Stitch Selection Lever on the right side of the cloth plate;
pull it toward you, releasing the thread chain from the stitch tongue.
Raise the presser foot and carefully flip the fabric over so that
the lower looper side of the previously stitched seam will be
overstitched.
Place the fabric under the presser foot so that the first stitch will
enter the fabric when you begin stitching.
Slide the Stitch Selection Lever toward the body of the overlocker.
Stitch for about 1", overstitching the previous stitching. Guide the
fabric so as not to cut the previous stitching. Optional: Rotate upper
knife up to deactivate.
Raise the toe of the presser foot and rotate the fabric 90° clockwise.
Stitch off the edge of the fabric.
If the upper knife is up, rotate it down into the cutting position.
