Elasticator
Thread the serger for a 4-thread overlock stitch. 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.
