How to Fix Constant Thread Breaks and Tension Issues

The Nightmare of the Bird's Nest

Nothing kills production speed like a thread break every 2 minutes. Before you call a technician, check these common culprits.

1. The Needle

When was the last time you changed it? A burred needle eye shreds thread instantly. Rule of thumb: Change your needle every 8 hours of stitching time.

2. The Thread Path

Re-thread the machine. Seriously. Often the thread has jumped out of the take-up lever or is not seated deep enough in the tension disks. Thread with the presser foot UP to open the disks.

3. The "H" Test for Tension

Stitch a satin column letter "H". Look at the back.

• Perfect: You see 1/3 bobbin thread in the center and 1/3 top thread on each side.
• Too Loose: You see mostly top thread on the back. Tighten the top tension knob.
• Too Tight: You see only bobbin thread on the back (or the bobbin pulls to the top). Loosen the top tension.
