Took needleplate off of Brother Serger 1034D now what?

Quite possibly the machine is not threaded correctly, the tension setting for that looper is too tight (could be the upper looper tension disk is stuck or dirty causing the thread to hang), or the thread is looped around something like the thread tree.

Replace the needles. Remove all the thread and re-thread from the beginning. Be sure to RAISE the presser foot before threading. Make sure to thread the threads in the correct order.

you might check your upper and lower knives. If they have a chip out of them or are dull some material just will not feed

the best thing to do is take the machine in to have it checked.
sergers are nice & very useful, I have a babylock serger with the jet-air
looper threading systerm, and I use it alot when making clothes.
I even used my serger to serge the ends of fabric that I haven't used yet
so the ends won't fray.

Hi
I found the manual on the Brother site.
http://www.brother-usa.com/ModelDocuments/Consumer/Users%20Manual/UM_1034D_ENES_178.PDF
Look at page 21 onwards of the PDF file for info on threading the machine.
Hope this helps!

I found that I had to remove the stitch finger to thread the machine properly. Do remember to re-install it before starting to sew. If you are using 3-threads only, then remove and store the stitch finger.
Puzzled that this instruction is not in the threading section of the manual.
