My xl-5700 the needle keeps breaking or the thread keeps getting all bunched up plus I lost my instruction manual can I gat a new one

These are the instructions in the manual:
Adjusting the Thread Tension
Balanced thread tension:
Small amount of the needle thread shows on the wrong side of the fabric.
When the needle thread tension is too tight:
The bobbin thread shows on the right side of the fabric. Reduce the tension by turning the tension dial to a lower number.
When the needle tension is too loose:
The needle thread forms loops and the stitches look shaggy.
Increase the tension by turning the dial to a higher number.

However, if you have recently changed the needle check that it is pushed right up in the slot. Other thing that springs to mind is making sure that the bobbin thread is correctly placed in the bobbin, and that the chamber is not full of lint and threads.

Most likely your top thread is not threaded correctly. Unthread and rethread. Check with your manual to make sure you have threaded correctly. Thread bunching up on bottom indicates top thread is threaded wrongly.

try these suggestions
change the needle
check the needle plate for burrs

Skipped stitches
1. The needle is not inserted correctly
Remove needle & reinsert needle( flat side towards the back of machine)
2. The needle is damaged
replace with new needle
3. The wrong size needle is being used
Choose a needle to suit the thread & fabric
4. The foot not attached correctly
Check & attach correctly

try another needle
rethread the machine top & bobbin
clean under the needle plate & in the bobbin area for lint or threads
if none of these things help then I suggest the machine get's serviced just
incase the timing is messed up

The needle thread breaks
1. the needle thread is not threaded properly
2. The needle thread tension is to tight
3. The needle is bent or blunt
4. The needle is incorrectly inserted
5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew
6. the threads were not drawn to the rear after sewing
7. The thread is either to heavy or to fine for the needle

you need to go to this webpage http://welcome.solutions.brother.com/bsc/public/us/us_ot/en/doc/manual_index.html?reg=us&c=us_ot&lang=en&prod=hf_xl5130eus&dlid=&flang=English&type2=-1 and download the instruction manual for this model. It has the threading up instructions plus selecting stitches, winding a bobbin etc.

The thread breaking is most likely due to incorrect threading up of the top thread. I suggest that if you can, you print out the manual, put into a little folder and place beside the machine and refer to it often. Follow the instructions in it on winding a bobbin, putting it into the bobbin case correctly and threading up the top thread. Make sure the bobbin goes into the case the correct way, as per image.

Remember, ALWAYS THREAD UP TOP THREAD WITH THE PRESSURE FOOT RAISED, this keeps the tension discs open so the thread can seat into the tension device correctly. And you must get the bobbin thread into the tension spring fully and then place the bobbin case into the shuttle using the little latch so it stays in place.

Also, new needle for every new project, and put the needle in "flat shank to the back". It will take standard domestic sewing machine needles 705/130H but it is important to select the correct sized needle for the fabric you are sewing so that the needle can penetrate the fabric but not leave big holes. So for light weights like chiffon you want a size 60 or 70. For medium weights a size 80 and for heavy fabric like denim or a coat weight wool you would use size 100. Ball points for stretch fabrics so that the needle pushes between the fibres and a regular point for woven fabrics.

I trust this helps you out, 4 thumbs up if so. Thank you.

Try this-When you pull your thread through the channel for the automatic needle threader, make sure you pull back on the thread hard. There is a groove that the thread must pass through to keep it from breaking. I had mine in the shop for the same problem and that is what they had me do. No more breaking.

try rethreading machine
thread tension is to tight -try 3-5-see if that works better
change needles
thread might be caught around spool pin -tension dial
needle & thread may not be compatable-try this & see if it works for you
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

the needle thread tension is wrong
bunching up under the material indicates that it is too loose

Try a new needle, making sure it is put in properly. A bent needle can break thread. Make sure top tension is set properly.
