The instruction manual recommends lubrication for the DW756 and DW758 every 60 days, what type of lubrication should I use? Where can I take it for this service?

There is no lubrication necessary as it is a sealed unit, we recommend blowing out the unit with compressed air to insure the best performance of the bench grinder. We are in the process of having this statement removed from the instruction manuals. If you would like to get this unit serviced, we recommend taking it to a DEWALT Factory owned or authorized repair center. For the location of the center nearest to you please use the Service Center Locator.
