Why is water escaping at the chuck during operation of my Hilti DD 150-U Drill?
If water is escaping at the chuck during operation of your Hilti Drill, it could be due to a few reasons. The diamond core bit might not be securely tightened in the chuck; tighten it securely, remove it, rotate it approximately 90 degrees, and refit it.

Finally, the carriage might have too much play, requiring you to adjust the play between the rail and carriage.
