  Your KaVo dental equipment handpiece may be noisy or heating up due to several reasons. It could be that the ball bearing is defective because of wear or soiling, in which case you should check the ball bearing and replace it if necessary. Also, prolonged operation at a very high load can cause this issue, so rectify the cause for the high load, increase the speed, and use a tool with a smaller diameter. An electronic fault in the control unit may also be the cause, so check the controls and have them repaired if necessary.

  If your KaVo dental equipment handpiece cannot rotate or temporarily shuts off, it might be due to several reasons. The handpiece may be blocked, or the clamping system may be open; in this case, close the chuck correctly with the tool in-situ. Another possible cause is a cable break, so check the line, including the plug-in connections, and exchange it if necessary. Finally, an electronic fault in the control unit could be the problem, so check the controls and have them repaired if necessary.

  If the tool is not tightly held by the chuck in your KaVo dental equipment, it could be because the tool shaft and chuck diameters are not the same, so use a tool/chuck with a suitable diameter. Alternatively, the chuck may be worn, in which case you should replace it.
