Drawing the Bobbin Thread to the Top of
the Quilt
1. After threading the machine and inserting the bobbin
case, plug machine in and turn on the power. Place
quilt sandwich under hopping foot.
2. While firmly holding the tail of the needle thread with
the left hand, choose one of the following methods to
cycle the needle through one full rotation in order to
bring the bobbin thread to the top of the quilt.
A. Foot Pedal Method: LIGHTLY tap the foot pedal to
make the needle go down. Then LIGHTLY tap again
to bring the needle up.
B. Needle Up/Down Button Half-Stitch: Locate the
Needle Up/Down Button in the center of the color
touch-screen main display. Press once to cycle the
needle down. Press again to cycle the needle back up.
C. Needle Up/Down Button, Full-Stitch: Locate the
Needle Up/Down Button in the center of the color
touch-screen main display. Press and hold briefly to
cycle the needle through one complete stitch cycle
(down and back up).
3. Pull the fabric 3-4 inches away while holding the needle
thread.
4. Bobbin thread will pull up and through to the top, al-
lowing you to grasp the loop and pull it to the desired
length.

IMPORTANT NOTE: Top thread tension should be
adjusted only after the bobbin case foundation tension
adjustment is made.
Puckering, gathers and thread breakage occur when the
top tension is too tight. Loops and thread nests occur on
the back when the top thread tension is too loose. (See
Figure 18 on next page.) Tension may need to be adjusted,
depending on the fabric, thread or batting used in each
project.
Unlike the bobbin case adjustment, which requires
minute adjustments (like the tick of a clock), the top ten-
sion knob may require turns anywhere from 1/4 of a turn
to 2-4 turns to achieve balanced tension.
Tighten Top Thread Tension
To adjust the top tension tighter, turn the top thread ten-
sion knob (page 10, Figure 1, #5) clockwise.
Top Thread Tension Adjustment
Checking and Adjusting Bobbin Case Tension
The bobbin case 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 lift the bobbin case up from your hand. While
gently moving the finger in a left to right motion (not
up and down, which is not consistent), the bobbin case
should slide slowly down the thread, like a spider on its
web.
The small screw in the center of the tension spring is
where the tension adjustment is made (see Figure 17).
Turn clockwise to tighten and counter-clockwise to loosen
the bobbin case tension. Turn the tension adjustment
screw in small increments. Check the bobbin tension
every time a new bobbin is inserted�
Tighten Bobbin Case Tension
The bobbin case tension is TOO LOOSE if it will not lift
up onto its side. Turn adjustment screw clockwise to
tighten. The bobbin case adjustment screw requires very
small adjustments. Think of the “tick of a clock” . Adjust,
then check. Adjust and check again.
Loosen Bobbin Case Tension
The bobbin case tension is TOO TIGHT if it lifts out of
your hand. Turn adjustment screw counter-clockwise to
loosen. The bobbin case adjustment screw requires very
small adjustments. Think of the “tick of a clock” . Adjust,
then check. Adjust and check again.
