Juki DNU-1541 Mechanical Sewing Machine - Page 7 Questions & Answers
Hi! I have a Juki HZL-25Z. The under side of my fabric is getting birds nest. So I know its the top tension but I have no idea how to fix this!
To be sure it is top thread, suggest you try a thread of a different color other than the bobbin.
Assuming its top thread, you need to increase top thread tension.
Other causes; Uneven feed of top thread can cause nesting of top thread. The machine uses a horizontal spool for top thread. Be sure you use a spool cap that is as big or larger than the spool. Pay particular attention to threading instructions on which direction the thread drops from the spool. If backwards, flip spool.

Can you get a walking foot attachment for a Juki industrial sewing machine
To attach the foot: First Hold your Walking Foot and raise its Lever. Keep the lever raised and hook the walking foot around the shank / presser bar. Slide the foot up and down until you've lined it up with the hole, so that you can insert the set screw. Put the set screw in and tighten with the screwdriver.

Juki e6 error
What is the E- 6 error in juki DDL-8500 chaina Machine
Hello! I have a Juki DDL-8100 e. the thread is constantly breaking when I go through thicker fabric - bobbin seems loose too.. could anyone help?
I'm not familiar with this machine but it sounds as though your top tension is too tight so that when you sew through heavy material the thread isnt slack enough to go through that extra thickness and so simply snaps. Try reducing the tension a little at a time and see how your stitching is affected.
Another issue might be that you are trying to sew a heavy fabric and using too light a thread. You need to match your thread to the job in hand. For a thicker thread you need heavier top tension. If your machine has been correctly serviced you should not have to alter the bobbin tension at all under normal circumstances as thicker thread will automatically have a heavier tension as it goes under the bobbin case spring and so you have to match this heavier tension with a higher top tension in order to get a perfect lockstitch.
I hope this helps.
