Correcting Common Issues
Skipped Stitches Corrective Measure
• Thread tension too tight
• The needle is bent or not installed properly
• Tension is not balanced
• The needle hits the needle plate
• Improper threading
• Loosen top tension. Re-check top and
bobbin tension
• Replace or correctly change the needle.
Make sure that the needle is pushed up into
the needle bar clamp until it can go no
farther (visually check that it is up to the
top of the stop/sight hole above the needle
bar clamp screw). Failure to do so can cause
damage in the bobbin area and throat plate.
• Balance the tension of the needle thread
after ensuring the bobbin tension is adjusted
correctly
• Replace needle with a new one.
• Inspect that the thread take-up lever,
thread stirrup or tension spring are all
threaded correctly.
