Always try a brand new needle first--a dull or bent needle will skip stitches. AVOID old or bargain bin threads! Be sure to use needles that are compatible with the thread and fabric you are sewing. Using the wrong type of needle will frequently cause skipped stitches, ie ball point needle on woven fabric. If you have exhausted all your ideas, it could be possible the machine is somewhat out of time.

Lower your needle. If up to high can't catch the bobbin thread.

I have the book on that machine as well and I have had that problem. Here is what had happened to me: I was soooooo tired of that shreading thing that I took a flashlight and aimed it up the nose of the machine by the lightbulb and fould there to be a nice little rats nest wrapped around the take-up lever and the needle bar. I spent the next three hours getting to that nest with the skinniest and longest tools I could find. Oh it is was fun!

Rule of thumb.. Loops on the bottom, problem on the top. Loops on the top, problems on the bottom.
Set your upper tension at 4, and rethread the machine from the top. Just before you thread the needle, but the presser foot down. If the thread pulls right thru easily, then the thread is not thru the tension wheel right. Because, if you can't pull the thread thru with the presser foot down, you have it threaded right.

Deep breath. Ohmmmmm.... ok now.
Few things you need to know.
1. Try to remember TTN when you run into problems like this it stands for Thread, Tension, Needle. Contrary to popular belief, there is no such thing as universal thread and needles. You'll need to determine what kind of thread and needle is best for your application.
2. When things gets bunched up under the fabric it Usually means that the tension for the top thread is too loose. However, a bad, bend or just plain wrong needle will cause these problems too.
3. Always grasp the threads (both top and bottom) and pull gently backwards when starting a seam. Some old school seamstresses and seamsters say to make sure your needle is at its upper most position (just before it starts to move down) before you begin sewing.
4. since you've had a couple instances with this issue... you might have to clean the bobbin race area. I'm a bit reluctant to tell you about this but remove the bobbin and look carefully for other stray threads, dust bunny's etc.
I hope this helps some. ;o)

Bobbin thread being too loose is due to two possible factors. The upper thread may be too loose allowing the bobbin thread to pull it under the fabric, or the upper thread may be too tight in which the bobbin thread will pull up to the top. Try adjusting the top tension to see if you can correct it. If it doesn't fix the problem, take out the bobbin and look for a screw on the bobbin case. If your bobbin case comes out from the underside of your machine, the screw is on the side. If yours is a drop in bobbin, it will usually be under the faceplate so you might have to take that off too to get to it. Turn the screw clockwise to tighten the bobbin, counterclockwise to loosen it. Only go a quarter of a turn at a time so you won't overshoot the mark.Then try by re-threading and sewing.
The basic procedure for threading is as follows:----------
Note that Pfaff sewing machines thread from left to right, not right to left like other sewing machines. The upper tension discs should be raised at their highest position while threading, and the presser foot should be raised up until you thread the needle. Drop the presser foot right before you thread the needle. The prevents thread problems during use.------------- Insert a full bobbin and retrieve the bobbin thread through the thread plate. Raise your sewing foot and needle to its highest position; hold the needle thread taught with your left hand, lower the needle into the thread plate using your right hand, and then raise the needle. As you raise the needle, the needle thread will catch the bobbin thread, and pull it up. There should be a loop of thread intertwined with the needle thread. Use tweezers, your finger, or a straight pin to retrieve the bobbin thread that is visible through the thread plate, and pull it through the plate.Place the fabric under the presser foot, and drop the presser foot. Choose the stitch you want to use from the top stitch display, right above the top thread feed. Press the '0-9" button located on the sewing machine's front panel, and a display screen will come up. Input the thread number, and press the 'OK' button located on the sewing machine's front panel.-----------this is procedure. If problem persists.Remove bobbin and clean lint from bobbin and re-tight the bobbin properly, then check.This should help.Thanks.Helpmech.
