Husqvana 870 sewingmachine Jumping off the uptake lever How do I fix this.

Maybe there some thread stuck between the upper tension lever and cause it to do this. On it could of jumped time. I would call my local sewing machine store and ask them whet it popped. It co

I have an old Pfaff that the top thread "jumps" out of the take-up lever when I sew fast. I simply closed off the opening at the top of the take-up lever with tape. No more jumping!

Be sure that when you thread the top thread, the presser foot is ALWAYS IN THE RAISED POSITION.

I have a different machine with the opening on the top of the take-up lever and the thread "jumps" out when I sew fast. I simply folded a piece of tape over the top of the opening and it doesn't jump out anymore... Just create something that will close the opening at the top.

Do you mean the thread comes out of the take-up lever when you sew? I have an old Pfaff that if I sew too fast, the thread "jumps" out of the take-up lever and then it's an instant mess of thread. I fashioned a small piece of tape to cover the opening in the take-lever and no more problems. Something like a drop of hot glue may work too.

If the thread is tightening at the take-up lever and eventually breaking, it is most likely because the thread is not advancing properly through the tension disk or the thread is hanging up somewhere between the thread spool and take-up lever. If you watch it closely, you may see the thread tightening and then be able to discern where the problem originates. (Make sure the thread is not hanging up at the thread spool.)

Slow down the speed of your machine.

I have a machine (not embroidery) that the slot on the take-up lever is rather large and the thread will jump out if I'm sewing fast. So, I placed a piece of scotch tape across to close the gap, fold the tape in half so it covers the sticky part. Technically, it has closed the gap so the thread can't jump out. Works just great.

some machine have that problem, I had to fix that problem on one of my personal machine, , take a pair of pliers and gently close the thread take up lever just enough to stop the thread from coming off

if possible take a piece of cloth and place it over the take up lever and get a pair of pliers and gently close the take up lever alittle bit just enough to keep the thread from coming out.

take up lever--try putting some tape on it to see if that will stop the thread from coming off.
also change the needle--make sure is the correct one for the fabric

I had a sewing machine that the thread would jump off the thread guide & it had to be bent just a little with small plyers to keep the thread from jumping off constantly
hope this helps

if you have the machine threaded correctly, try threading the takeup lever from the opposite side so the thread crosses over itself and see if that helps.
