Maintenance This is a good time to inspect the rest of the XT machine and perform any other necessary maintenance, see page 30. This unit will display a “Maintenance Alert“ when maintenance is required. The screen will display: For best performance and longevity of the Auto Sharpener we highly recommend the use of a dust extraction system. For more information contact DAREX @ 800-547-0222.
Maintenance WHEEL MAINTENANCE These wheels are maintenance free from truing and dressing but will need to be cleaned periodically. Disconnect the power from the machine using a lock out tag out procedure. After removing the wheel from the sharpener, saturate the wheel with any type of oil-less solvent, such as Automotive Brake Cleaner. It is helpful to use a soft bristle brush and lightly brush the saturated wheel, loosening the impacted grinding particles.
Trouble Shooting The unit stopped working and the screen displays “Sharpening Interrupted”: • This message will appear if the user presses the “Stop” button during sharpening. It will also appear if the controller detects a large load on the chuck turning motor. This is typically caused by dirt or grit accumulating on the Chuck Body, Chuck Tube Liner, or the Cam Follower Assembly. Turn the machine off and perform the standard maintenance procedures listed on pages 29 & 30.
