Presser Feet & Accessories
The following presser feet and accessories are available for BERNINA overlockers except the L 220. Some
attachments are included with the purchase of the overlocker and others are optional depending on the
model. Each presser foot snaps onto the shank of the overlocker, easy to change without the use of addi-
tional tools. The Gathering Attachment, the Guide for the Multi-Purpose Foot, and the Right & Left Seam
Guides are attachments used in conjunction with a presser foot.

Elasticator: Attaching Elastic
Fabric: Medium weight cotton, 3” x 14” and
12” length of ½” nylon or cotton braid elastic
Needle: 75/11 Stretch or Ballpoint
Thread: 2 cones of overlocker thread and 2 cones of Woolly Nylon
Presser Foot: Elasticator
Stitch: 4-thread overlock
Thread the overlocker for a 4-thread overlock using Woolly Nylon in
the upper and lower loopers. Adjust settings as directed below.
Attach the Elasticator to the overlocker.
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 overlock a few stitches to catch and
straighten the elastic along the right edge of the slot. Turn the hand-
wheel to lower the needles.
Lower the roller guide. Using the small screwdriver, loosen the set
screw on the front of the elasticator and adjust the guide plate to the
width of the elastic; tighten the set screw.
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 stitching. 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.
Stitch the elastic onto the fabric letting the presser foot stretch the
elastic for you.
Return all settings to normal.
