Thread tension too tight
•
Check bobbin case tension and then check top thread tension.
(For more information about adjusting tension, see
Bobbin and
Thread Tension Adjustments.
)
Improper threading
•
Inspect that the thread take-up lever, thread stirrup, and tension
spring are all threaded correctly.
The Needle Breaks
Corrective Measure
The needle is bent or not installed
properly
•
Replace or correctly change the needle. Make sure that the
needle is pushed up into the needle bar clamp until it can go no
farther (visually check that it is up to the top of the stop/sight
hole above the needle bar clamp screw). Failure to do so can
cause damage in the bobbin area and throat plate.
The needle hits the throat plate
•
Correctly position the needle, throat plate, or hopping foot.
Replace with a new needle.
Stitches are Puckered
Corrective Measure
The hopping foot applies too much
pressure to the material
•
Decrease the pressure on the hopping foot by loosening the
nut at the base of the hopping foot shaft. Adjust to the proper
height. Note: When tightening the nut on the hopping foot shaft,
be careful not to tighten so tight that it rotates the bar.
The tension is not balanced
•
Balance the tension of the needle thread after ensuring the
bobbin tension is adjusted correctly. (For more information
about adjusting tension, see
Bobbin and Thread Tension
Adjustments.
)
Needle too large for quilting fabric
•
Replace the needle with a size better suited for the fabric.
Poor Stitch Quality
Corrective Measure
The tension is not balanced
•
Balance the tension of the needle thread after ensuring the
bobbin tension is adjusted correctly. (For more information
about adjusting tension, see
Bobbin and Thread Tension
Adjustments.
)
Bobbin case is damaged, corroded,
dirty, etc.
•
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.
Moving the machine too fast for
needle speed selected
•
Synchronize machine movement and needle speed to get
roughly 8 to 10 stitches per inch. Elongated stitches are an
indication of moving the machine too fast for the current speed.
