The Needle Breaks
Corrective Measure(s)
The needle is bent or not
installed properly
• Replace the needle. Make sure that the needle is
pushed into the needle bar clamp until it can go no
further. Visually check that it is up to the top of the
sight hole above the needle bar clamp screw. If the
needle isn’t installed properly, it 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(s)
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 Bobbin Tension
and
Quick-Set Tension
in the
Using Your Machine
section of this manual.)
Needle too large for
quilting fabric
• Replace the needle with a size better suited for the
fabric.
Poor Stitch Quality
Corrective Measure(s)
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 Bobbin Tension
and
Quick-Set Tension
in the
Using Your Machine
section of this manual.)
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 fabric too fast
for needle speed selected
(Manual mode)
• Synchronize fabric movement and needle speed to
get your desired stitch length. Elongated stitches are
an indication of moving the fabric too fast for the
machine's current speed.
