How to Maintain an Overlock Machine

A simple maintenance routine that keeps your overlock machine running smoothly and extends its life.

An overlock machine cuts fabric as it sews, which means it collects lint faster than a lockstitch. Regular maintenance prevents most problems.

Daily

  • Blow or brush lint from the looper and knife area after each shift.
  • Check the oil level.

Weekly

  • Clean the feed dogs and remove trapped thread.
  • Inspect and replace dull knives.

Monthly

  • Oil the looper and needle bar mechanisms.
  • Check looper and needle timing.
  • Replace worn needles as a set.

A well-maintained overlock machine runs faster and produces cleaner seams. For a full oiling routine, see our lubrication guide.
