Some troubleshooting tips for your Elna T34D overlocker

Make sure your tension is not too tight and that there is no fluff or cotton stuck in between your tension plates. I sometimes use a string of the stitch to pull in between the tension plates. I always set the needles tension first and then i balance the tension of the upper and lower looper. Make sure the cotton are not looped around a guide. Black cotton and some cottons can build up their own tension. Try different cotton. I've had many a headache with this problem.

Check that the needles are not blunt or bent. I always use schmetz needles. If your needle plate has any damage where the cotton can get hooked. You can see this in the pictures below. Use a small file or sandpaper to remove it. The stitch tongue must be very smooth and the stitch must slide of smoothly. Check that your lower looper point does not have a sharp hook(bur) on it. You can use a very fine water sandpaper to remove it.

If your needles are touching the looper, i could indicate that your lower looper is out of position. (Always check this with new needles) You can get the Elna T34D overlocker instruction manual from sewingnz shop.
