Question about Euro-Pro Shark 80 - 7133

1 Answer

I keep having the same problem. I have the 7133 sewing machine and the top thread keeps getting stuck on the bottom. It's not the bobbin thread that does it but the top thread which gets caught on the hook below. I've rethreaded both top and bobbins and I've cleaned and oiled the hook area, plus used a new needle however it keeps doing it.What am I doing wrong?

Sounds like insufficient tension on the top thread. THIS may be due to variation in the thread itself or incorrect adjustment.

ALSO I recently found out that some bobbins have a metal core that can catch the thread as it goes over. The person recommended using the plastic bobbins that have smooth angled sides.

My Shark 7133 slowed down while sewing and stopped. The handwheel won't turn at all. I cleaned the bobbin area but it still won't work. The light switches on and the machine motor reves up but...


Slacken the stop motion as if to wind a bobbin and press on the foot control, if the motor runs really fast then you have either thread stuck in the bobbin case area or you may need to oil the machine

Bobbin thread keeps knotting


1. Do you mean that there are knots in the bobbin thread?
2. Is the bottom thread in your stitching looping and knotting.

If yes to 1. you need to rewind your bobbin fresh, and keep slight tension on the thread reel that you are winding it from. Put the handle of your scissors into the top of the reel to apply a gentle pressure while winding. Keep your eye on the bobbin as it winds and give it a nudge with a finger tip to ensure it winds the bobbin evenly top, middle and bottom.

If yes to 2, then you need to check your bobbin threading, is the thread even under tension. Is the bobbin tension set correctly. Break out your manual and revisit this to ensure it is set correctly.

Lower bobbin looping


The top thread is loose and the bobbin thread is pulling the top thread down

Always thread the machine with the presser foot up and see if this eliminates the problem.

Sounds opposite of the problem, but it is very important to do this to assure the tension control can keep the top thread at the correct tension to form a proper stitch.

If the machine is threaded with the presser foot down, the tension control is closed and the thread cannot seat into the control as it should.

Bottom tread keeps jamming and getting all knoted up. The display gives me an E6 error code. what can i do


try re-threading your machine. usually when the machine is jammed at the bobbin or when the needle gets stuck to the bobbin thread, it means that there is an error with the thread. make sure that the thread isn't pulled through the wrong side of the needle, wrapped the wrong way around the wheels on the top, and that the bobbin is threaded correctly. if this doesn't work, you may want to contact their hotline.

My sewing machine keeps getting jammed when sewing. the top stitch keeps getting tangled in with the bobbin thread and jamming up the machine.


Hello,
Here are a couple of things to try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.

I hope this helps.

Thread tension for regular seam sewing


oil the shaft for the presser bar and keep moving it up and down(it may take a while) until it moves freely. Always use Sewing machine oil Not 3N1 oil.
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on top and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension). If you have loose thread on top your top tension is probably too tight and your bobbin thread too loose

Hi FixYa,

I'm fifi1076, and I'm having quiet a good bit of trouble with my sewing machine.

I'm new at this site so I don't know if I'm doing this correctly or not so please
forgive me if I do something I'm not suppose to do!!!!

I copied this question from off of this site for I wanted to make certain that
whoever answers my question will understand that all of the question
doesn't pertain to my problem.

"when we have it threaded the top thread keeps getting jammed up in the bottom bobbin. if i redo the bobbin as shown in manual then the bottom thread will not loop so it will stitch"

This is the only part that pertains to my problem...... when I have it threaded the top thread keeps getting jammed up in the bottom bobbin......and I can't get it to sew at all....it won't do nothing.....the motor will just sit there and grind.

If whoever can help me with this and can give me a solution I will be forever gratefull

Thanks,

Kay Nowicki
