Bobbin and Thread Tension Adjustments
Inserting the Bobbin
1.
Place the bobbin in the bobbin case so that the thread pulls off
clockwise when viewing the open side (Photo 9).
2.
Slide the thread through the slot and under the tension spring
leaving 5-6 inches of thread hanging loose (Photos 10 and 11).
3.
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 alignment notch in the middle of the hook.
Push the casing in until it stops in place. Push inward until it
clicks (see Photo 12).
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.
4.
Turn off the power switch while inserting the bobbin case or
anytime the hands are near the needle area.
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.
2.
While firmly holding the tail of the needle thread, press the needle
up/down button with free 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 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 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 Photo 13). Turn clockwise to tighten
and counterclockwise to loosen the bobbin case tension.
Check your bobbin tension every time a new bobbin is
inserted.
