Modified on Fri, 09 Sep 2022 at 09:22 PM

This video explains how to clean and adjust the HF collet on the HF milling motor of a F serie.

Collet setting process: 

In your current system 4041 DC-S with collet C4 your collet set process looks as follows: 

  • Apply compressed air
  • Screw in collet with inserted tool or c-lock pin
  • Adjust the stroke by loosening collet ½ turn
  • Insert set screw and tighten set screw to prevent collet from turning 
  • Insert tool 
  • Stop compressed air supply 

Attention: The collet is not protected against rotation/loosening if the set screw is not firmly tightened.  


Clean collet every week and insert collet according to set process.

During yearly maintenance it could be recommended to replace the collet to ensure the clamping power
