Dewalt 780 miter saw

Does anyone know if the "thrust bearing," the dime-size circular ball bearing ring in the pivot recess, is supposed to be lubricated? I can see factory lube on the O-ring that surrounds this area, but I can't tell if the ball bearing ring should be greased or not. Mine was all choked with sawdust, so I blew it out with compressed air and would like to know before I put it all back together whether or not the factory wants that to be lubed. Thanks.

Welcome to the forum.

 

From the DWS780 Instruction Manual, page 14: "All bearings are sealed. They are lubricated for life and need no further maintenance."

 

Here is the manual:
