threading for twin-needle stitching
For best results, use No. 50 mercerized or synthetic thread. Thread the
machine as for single-needle stitching, except pass thread between center
and back tension discs, and through right eye of needle. Attach secondary
spool pin in hole on top cover. Pass thread from second spool through guide
(by-passing the snap-in thread guide post) as illustrated, then between
center and front tension discs. Thread through remaining points, making
certain to omit the thread guide above the needle and pass thread through
left eye of needle.
