Stitch Quality is Poor Corrective Measure

• Adjust the tension of the needle thread after ensuring the bobbin tension is

adjusted correctly (see pages 19-20).

• Tension is not balanced

• Since thread slides over the surface of the bobbin case at a high speed,

make sure the case is free of any lint or foreign matter that could impede

thread passage through the machine.

• Bobbin case is damaged,

corroded, dirty, et cetera

• The My Speed setting should be adjusted to a value that will allow you

to sew comfortably and conﬁdently with the foot pedal fully depressed.

• Moving the fabric or

depressing the foot pedal

inconsistently

Tension Is Poor Corrective Measure

• With some threads, lint and other material can build up under the tension

leaf spring and begin to lift the spring. This reduces the spring’s ability to

compress against the thread. By inserting a needle under the spring and

clearing out the lint, the bobbin tension will return to the previously set

tension.

• Lint caught under the tension

spring in the bobbin case

• If the bobbin is wound too tight or too loose it can lead to poor and

inconsistent tension. Make sure when the bobbin is wound that the thread

tension is not so tight that the wound bobbin thread feels hard and causes

the bobbin sides to bulge. It should also not be so loose that the thread is

spongy, which can cause the thread to tangle as it is wound.

• Poorly wound bobbin

Hand Wheel Won’t Rotate Corrective Measure

• Turn off the machine and remove the power plug from the electrical

outlet. Remove the bobbin case from the machine. Lubricate the hook, then

manually rotate the hand wheel clockwise and counter-clockwise several

times. Remove the thread caught in the hook.

• Thread is entangled and

caught in the hook

Thread Nests Under Quilt Corrective Measure

• Check that the machine is threaded correctly. Make certain that the thread

is ﬂossed snugly in place between the two tension discs. If the machine is

correctly threaded, tighten the top tension by rotating the tension knob

clockwise.

• Not enough tension on top

thread

• Refer to the threading diagram and threading instructions on pages 16-17.• Improper threading

Motor Fails to Run Corrective Measure

• Turn the machine on only by using the switch on the back of the power

pod. Verify the power cord is plugged in tightly at both the machine and

the power source.

• On/Off switch is off or power

cord is loose

• Verify that the foot pedal is plugged in. If the main screen status message

in the upper left hand corner says “Check Pedal”, then the pedal is not

properly installed.

• Foot pedal is unplugged
