Bobbin and Thread
Tension Adjustments
Insert Bobbin into Bobbin Case
1.
Place the bobbin in the bobbin case so that
the thread pulls off clockwise when viewing the
open side.
2.
Slide the thread through the slot and under
the tension spring, leaving 5-6 inches of thread
hanging loose.
Bobbin Tension
The bobbin tension is the foundation tension
for the entire machine. Always set the bobbin
tension
first
.
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 the
index finger of the opposite hand and while pulling
up on the thread and 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 (

). Turn
clockwise to tighten and counterclockwise to
loosen the bobbin case tension.
Insert Bobbin Case into Machine
1.
Turn off the power switch while inserting the
bobbin case or anytime the hands are near the
needle area.
2.
Do not lift the lever
on bobbin case. Fit the
bobbin case onto the hook spindle in the machine.
Rotate the casing until the open throat keys into
the middle notch in the hook. Push the casing in
until it stops in place. Push inward until it clicks
(

Drawing up 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.
Move the machine over the quilt to your starting
location.
2.
While firmly holding the tail of the needle
thread, press the needle up/down button with free
hand, causing the needle to go down through the
fabric and then back to the up position.
3.
Pull the machine 2-3 inches away while hold-
ing the needle thread.
4.
Bobbin thread will pull up through to the top
allowing you to grasp the loop and pull it to the
desired length.
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.
