3. Turn off the power switch while inserting the bobbin
case or anytime the hands are near the needle area.
4. Do not lift the lever on bobbin case. When placing the
machine fit the bobbin case onto the hook spindle 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 20).
Note: It is not suggested that the lever on the bobbin
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/down
button on the left handle.
2. While firmly 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 three to four 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
finger and while pulling up on the thread and gently
wiggling the finger 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 21). Turn clockwise to tighten and counter-
clockwise to loosen the bobbin case tension. Check your
bobbin tension every time a new bobbin is inserted.
Note: Bobbin tension adjustment is a minute turn of the
screw like the ticking of a clock.
