2. Overlockers (video)

2.2. Replacing a needle

Overlockers can usually be operated with one, two or three needles. A four-thread overlocker can be made down to a three-thread machine by removing one of the needles / leaving one of the needles unthreaded.

  • Turn off the machine.
  • Each overlocker has its own set of needles, check the device-specific number.
  • To gain more visibility, turn the presser foot aside using the lever behind the presser foot.
  • Cut the needle threads near the needle.
  • Loosen the needle screws using a small Allen key.
  • Remove the damaged needles and place them in needle waste for recycling.
  • Put the new needles in place, pushing them as high as you can into the slot.
  • Tighten the screws.
  • Thread the needle eye from front to back.
  • Test your stitch on a piece of fabric.
