Closer is slugish, it opens and closes, but slowly

Not enough holding force

  • Air pressure to low
  • Bar whip causing rocking in the collet
  • Blow bye of the seals

Collet closer does not open intermitantly

The collet closer adjustment knurled ring on the back does not turn easily

The knurled ring on the back is jammed and won’t turn
