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.
