Why is the thread looping/bunching under my fabric?
Thread looping under your fabric is usually caused by not threading the upper tension
correctly. With the presser foot lever in the UP position and tension set at 4, follow the
threading guides/graphics on the top of the machine.
1.Place the thread spool on the spool pin and secure with a thread spool cap.
2.While holding the thread with your right hand, use your left hand to take the thread and
take the thread and follow the thread path by bringing the thread down into the tension
channel around the bottom and up the other side.Continue to thread the machine, but do
not thread the needle.
Before threading the needle, perform this easy test to make sure the upper thread is
threaded correctly. Making sure the presser foot is raised, pull the thread. It should pull
easily. Now lower the presser foot, the thread should now resist when you pull it. There
should be a significant increase in the tension of the thread. If there is no increased
tension, the machine is not threaded correctly.
Why is my machine skipping stitches?
Skipped stitches can occur if needles are damaged or dull, or if they are incorrectly
inserted into the machine.
First, your needle may be dull or damaged and need to be replaced. You should also
check that you are using the correct needle for the type of fabric you are sewing. Refer
to the Needle/Fabric/Thread/Guide on page 11 of this manual.
Next, check that the needle is installed correctly. The needle needs to be pushed as far up
the needle shaft as possible. (It's easy to insert the needle halfway, clamp it down and think
it is installed correctly.) Also, the flat part of the needle should be positioned towards the
back. If the needle is not installed correctly, it will not be able to pull up the bobbin thread
and will cause skipped stitches.
