Troubleshooting
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 bobbin case side
of the machine), you will see the entire needle eye directly facing you.
This is 6 o’clock position.
• Make sure (a) the needle is installed all the way into the needle bar to
the needle-stop hole in the needle bar, (b) the long groove in the needle
is toward the front (bobbin case side), and (c) the scarf (scooped out
part of the back of the needle) is toward the back of the machine.
• The needle can sometimes be rotated to 5 o’clock (slightly right) or 7
o’clock (slightly left) to adjust for a more positive thread loop pickup by
the hook point.
Improper threading • Ensure that the machine is threaded correctly.
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 farther. Visually check that it is up to the
top of the stop/sight hole above the needle bar clamp screw. If the
needle isn’t installed properly, it can cause damage in the bobbin area
and needle plate.
The needle hits the needle plate • Correctly position the needle, needle plate, or hopping foot. Replace
with a new needle.
Stitches are Puckered Corrective Measure(s)
The tension is not balanced.
Top and bottom tension are both
too tight. • 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 Top Thread 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 Top Thread 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.
Loose Display Housing Corrective Measure(s)
Loose display housing Loosen handle bar clamp bolts, rotate handlebars to desired position and
push together, tighten clamp bolts.
