Gathering Attachment:
Gathering Fabric
If necessary, install the attachment base on your serger (700D and
800DL only).
Raise the cutting knife and adjust cutting width to 3mm. Slip Gathering
Attachment on to the fixing screw and metal post directly behind the
fixing screw. Hint: Place the horseshoe-shaped slot over the screw, then
rotate the attachment to lock over the metal post. Tighten fixing screw.
Set cutting width at 2mm (normal) and lower the upper knife into cutting
position. Locate and adjust the differential feed dial to 2. Using a fabric
marker, divide fabric into 3 sections along one 12” edge.
Turn the handwheel to lower the needles. (This also lowers the feed
dog.) Raise the presser foot and insert the fabric under the Gathering
Attachment, up against the needles. The fabric is lying against the stitch
plate.
Lower the presser foot and serge to the first mark.
Adjust the stitch length to 4mm and serge to the second mark.
Increase the tension on both needles to 7. Serge to the end of the
fabric.
Mark the sample: with Differential Feed; with Differential Feed & SL4;
with Differential Feed, SL4 and tightened needle tensions.
Mount the sample on the following page.
Return all settings to normal.
The attachment base can remain on the machine.
