Take the bobbin carriage out and clean it really good. Use the little brush that comes with your machine and brush everything. When m y machine jams up like that it usually means there is lint or thread caught in the bobbin carriage.

What to do to fix the bobbin thread from jamming up everytime


There are a couple of reasons that can cause this.
a. Raise the pressure foot. As you load the top thread give small tugs to check for snags. They must be stopped.
b. Once the top threading is done on top lower the pressure foot. Now, give a tug on the thread. Is the tension really hard or just average? You may need to lower the tension to stop the jamming of the bobbin thread.
c. Clean the bobbin area. Check the bobbin tension and adjust as you need to.
d. Put a drop of oil on the race. (Thing the bobbin case sits on)
e. As the bobbin hook (sharp thing) is rotating does the bobbin case move back and forth a lot. You may need to adjust the bar that is next to the bobbin case so it can't rotate. Usually you will need to move it forward.
SEE INSTRUCTIONS HOW TO ADJUST THE BOBBIN. TENSION OF UPPER AND LOWER THREAD MUST BE RIGHT.

What are the normal tention settings


Tension settings are the upper settings and the bobbin settings.

The top settings are generally started at four and adjusted up or down as needed for a good stitch.

The bobbin stitch is a little more difficult but I've attached a guideline. Usually the bobbin stitch doesn't need readjusted too often unless there is a major difference in thickness of the thread being used.

My machine wont sew a stitch. It goes into material with thread but no stitch. The bobbin on the bottom is having troublr picking up the thread ant the top thread is way too tight and set at 3....I also...


I hope these suggestions aren't aggravating. Not knowing your familiarity with the machine:

1. Is the bobbin spinning clockwise in the holder?
2. Did you make certain to pull it through the delivery eyelet under the spring?
3. If you do need to remove the bobbin case, be sure to turn off the machine. It won't come out unless it is off. There could be something jammed up behind it?
4. Upper thread tension is normally 4.
5. Lower thread tension is factory set for you--the small screw on the side of the bobbin case should be horizontal -- straight across. you may adjust that with a screw driver to loosen it slightly. Lefty Loosey Rightie Tightie. But Slightly Slightly. :) hope that helps in some small way.

My machine wont pick up the bobbin thread, and when it does, and I start sewing, it keeps jamming, and the thread locks around the bobbin spindle. It keeps sewing in one spot, which I have to cut the...


check that the bobbin thread is pulled thru 'the tongue' of the bobbin case: that is what controls general tension of the lower thread. also make sure the upper thread is threaded thru the tension disk and the disk is 'grabbing it'.

M machine stopped working properly. The lower thread is bunching, knotting and the fabric is being pulled into the bobbin compartment. The machine also makes loud noise. thanks


bunching lower thread is actually the upper thread not having enough tension due to mis-threading or wrong tension setting

Threading lower bobbin


There are some different bobbin cases for different machines but the one you have is a pretty common one with a finger sticking out on top. If you examine the bobbin case you will see a slot on the side of it and there is another piece of metal screwed onto it. This is the tension they are describing.
To thread it properly, turn the bobbincase upside down and insert the bobbin in the case so you can see it. Place your thumb on top of the bobbin and pull the thread through the slot on the side of the case and under the piece of metal(the lower tension) which I described to you earlier.. When you have done that, remove your thumb from the bobbin and pull on the thread. It should have some tension on it.
Next,placing a thumb or finger on the bobbin to keep it from falling out, turn the bobbin case over.
Keeping the finger sticking up lift the lever on the
front of the case and insert the bobbin and bobbin case onto the spindle inside the hook assembly(The part that is in the bottom of the machine that turns when the hand wheel is turned.) Don't worry about the thread that is sticking out.
Holding the upper thread under the presser foot ,turn the handwheel towards you until the top thread pulls the lower thread to the top. Pull the thread to the left of the machine, insert your fabric, lower the presser foot and begin sewing
One more thing , The finger sticking up on the bobbin case will go into a slot on the ring holding the hook inside the machine.
Hope this solves your problem.
Be sure you thread the upper part properly. It should go through the tension, then the take up lever and then the needle. Tension should be set at around 5
