Unable to thread lower looper on Babylock Eclipse BLE1SX

Have you tried to use the wire looper threaded to get the thread through the looper?
I have often used wooly nylon thread with the looper threader(above) (several thicknesses) using a clear dissolve The to clean out the tubes where the thread flows through the looper.
Apart from this you may require professional assistance by a qualified Babylock Technician

hi Goldie.
you have not said what make or model you have,so would not know what manual you would be after,
but his link might help you out on the looper.
How to get to lower looper to thread Google Search

are you using a wire threader or tweezers to thread up? also some overlockers have a slide mechanisim on the looper so you can get to the eyelet, not familiar with this model but your manual should show the threading method. I usually turn the flywheel so the lower looper is all the way to the left and thread up the lower thread carrier, then turn flywheel again to move it to the right, then using the wire threader, I hook the thread from the left and bring it over to the right side, then thread up the looper eye. Hope that makes sense to you

These machines have to have the threader tubes engaged. Do you have them set for threading? If it still doesn't thread you have to use the wire threader that was provided with the machine when you bought it. It might be in the storage compartment under the lower looper spool pin.

Apparently either you have no needle threaded to lock the stitch or both loopers aren't correctly threaded. You must thread your UPPER looper first (don't know what color yours is), LOWER looper next, RIGHT needle next and last the LEFT needle if you are using the 4 thread overlock stitch. It sounds like you are having trouble with your lower looper. Look for the lower looper threader to help you thread it. Your manual should show you a picture.

Make sure all the settings are as they should be for threading and try again.

You can manually thread the loopers with a very fine gauge guitar wire or beading thread (looks like fishing line) with a loop on one end to hold the thread.

If you still cannot get the machine threaded, take it to a dealer to see if they have a wire threader instead of the DIY method I explained.

Get a wire threader for the machine from the dealer and store it in a safe place as it is easily lost - I lost mine 2 years ago - they are so thin they disapear!

You need to contact a Babylock dealer. I am one. [email protected]

Do you know the looper threader broken can be repair by yourself? I suggest you to order the following product:

check to make sure it is not wraping around the upper looper. just stitch without the material and you will see it. but then you must rethread the upper looper and the lower looper again in the right order. hope this helps
