3. Turn off the power switch while inserting the bob-
bin case or anytime the hands are near the needle
area.
4. Do not lift the lever on bobbin case. When placing
the machine fi t the bobbin case onto the hook spin-
dle in the machine. Rotate the casing until the open
throat keys into the alignment notch in the middle
of the hook. Push the casing in until it stops in place.
Push inward until it clicks (see Figure 18).
Note:
It is not suggested that the lever on the bob-
bin case be used for this installation. The latch lever
should be used only for removal of the bobbin case.

Drawing the Bobbin Thread to the Top of the Quilt
1. After the machine is threaded, locate needle up/
needle down button on the left handle.
2. While fi rmly holding the tail of the needle thread
with the left hand, press the needle up/down button
with right hand, bringing the needle back to the up
position.
3. Pull the machine 3-4 inches away while holding
the needle thread.
4. Bobbin thread will pull up and through to the
top, allowing you to grasp the loop and pull it to the
desired length.
Bobbin Tension
The bobbin tension is the foundation tension for the
entire machine. To test that bobbin tension is correct,
hold the bobbin case in the palm of your hand with
the open end facing up. Wrap the thread around your
index fi nger and while pulling up on the thread and
gently wiggling the fi nger front to back (not up and
down which is not consistent), the bobbin case should
lift up on its side, but NOT lift out of your hand. If it
will not lift up onto its side, it is too loose and if it lifts
out of your hand, it is too tight. The small screw in the
center of the tension spring is where the adjustment
is made (see Figure 19). Turn clockwise to tighten and
counter-clockwise to loosen the bobbin case tension.
Check your bobbin tension every time a new bobbin is
inserted.
