Set tensions for a balanced stitch. Attach the Elasticator to the serger. Adjust stitch length to 4mm. Increase the presser foot pressure. Locate and raise the roller guide in the front of the presser foot. Turn the handwheel to lower the needles. (This also lowers the feed dog.) Raise the presser foot and insert the elastic through the slot and under the presser foot until it touches the needles. Lower the presser foot and serge a few stitches to catch and straighten the elastic along the right edge of the slot. Turn the handwheel to lower the needles. Lower the roller guide. Using the small screwdriver, adjust the guide plate on the presser foot to the width of the elastic. Locate the pressure adjustment set screw (on the top of the roller guide) and turn the screw counterclockwise to completely loosen the pressure on the roller. Place the fabric under the presser foot and begin serging. Slowly tighten the pressure adjustment set screw to increase the pressure on the roller and stretch the elastic. Note: Do not over tighten the screw. Excessive pressure on the elastic will bind the fabric. Serge the elastic onto the fabric letting the presser foot stretch the elastic for you. Trim and mount the sample. Return all settings to normal. MASTERING YOUR BERNINA® SERGERS 6/2006 50 ©2006 BERNINA® of America, Inc.
