Preparations
Thread tension
To obtain a perfect seam appearance and durability make sure
the needle thread tensions is correctly adjusted, i.e. the threads
evenly meet between the two fabric layers.
The following is valid for general sewing:
Bobbin thread is visible on the top side of the fabric:
The needle thread tension is too tight.
The thread tension must be corrected.
Top thread is visible on the underside of the fabric:
The needle thread tension is too loose.
The thread tension must be corrected.
For decorative stitches and buttonholes the top thread should
be visible on the underside of the fabric.
Inserting the bobbin
Insert the full bobbin (with the Pfaff logo facing towards
the bobbin case) in the bobbin case. When doing so, pull the
thread through slot A, then under tension spring B until it
rests in the opening (see arrow).
Check:
When you look at the bobbin and pull the thread, the bobbin must
turn clockwise
Inserting the bobbin case
Lift latch E and push the bobbin case fully onto pin C of
the sewing hook. Opening D of the bobbin case must face
upwards.
Check:
Pull the bobbin thread sharply. The bobbin case must not fall out
of the hook.
