QUILT MAKER PRO 20
• 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, (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.
Corrective Measure(s)
• 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.
• Correctly position the needle, throat plate, or hopping foot. Replace
with a new needle.
Corrective Measure(s)
• 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 Easy-Touch Tension™ in the
Using Your Machine section of this manual.)
• Replace the needle with a size better suited for the fabric.
Corrective Measure(s)
• 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 Easy-Touch Tension™ in the
Using Your Machine section of this manual.)
• 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.
• 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.
