The needle is not positioned
properly
• Position the needle properly to the needle bar. Inspect the
position of the needle to make sure the needle is at the 6
o’clock position. When you stand directly in front of the
needle, facing the front (bobbin case side) of the machine,
you will see the entire needle eye directly facing you. This is
the 6 o’clock position.
• Make sure (a) the needle is installed all the way into the needle
bar, and (b) the long groove in the needle is toward the front,
and (c) the scarf, the scooped out part of the back of the
needle, is toward the back of the machine.
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 C orrective Measure(s)
The tension is not balanced
• Balance the tension of the top thread after ensuring the
bobbin tension is adjusted correctly. For more information
about adjusting tension, see Bobbin and Bobbin Tension in
the Using Your Machine section of this manual.
Needle too large for
quilting thread
• Replace the needle with a size better suited for the thread.
Poor Stitch Quality Corrective Measure(s)
The tension is not balanced • Balance the tension of the top thread after ensuring the
bobbin tension is adjusted correctly. For more information
about adjusting tension, see Bobbin and Bobbin 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 machine too fast
for needle speed selected
(Manual mode)
• Synchronize machine movement and needle speed to get
your desired stitch length. Elongated stitches are an indication
of moving the machine too fast for the current speed.
