Inserting the bobbin
1. Remove the bobbin cover by sliding it towards
you.
2. Place the bobbin in the bobbin case with the
logo facing up and the thread unreeling from
the left of the bobbin. The bobbin will then
rotate counter-clockwise when you pull out
the thread.
3. Place your À nger on the bobbin to keep it from
turning as you pull the thread À rmly to the
right and then to the left into the tension spring
(A) until it “clicks” into place.
4. Continue threading around (B) and to the right
of the thread cutter (C). Replace the cover. Pull
the thread to the left to cut.
Note: The bobbin cover can be used as a magnifying
glass.
IDT™ system (integrated dual feed)
For sewing any fabric precisely PFAFF®
expression™ sewing machine provides the ideal
solution: the integrated dual feed,
IDT™
system. As
on industrial machines, the
IDT™
system feeds the
fabric from the top and bottom at the same time.
The material is fed precisely. On light fabrics such
as silk or rayon the dual feed prevents puckering
of the seam. The even feeding action also ensures
perfect matching of checked and striped fabrics.
The IDT™ system keeps all layers of quilt projects
aligned to prevent shifting of the top layers.
Engaging the
IDT™
system
Important: For all work with the IDT™ system, use
presser feet with the center back cut-out (D).
Raise the presser foot. Press the
IDT™
system
down until it engages.
Disengaging the IDT™ system
Raise the presser foot. Hold the
IDT™
system with
two À ngers at the ribbed ankle. Pull the IDT™
system down, then pull it away from you to release
the
IDT™
system slowly upward.
