When I turn the table I am getting metal on metal grinding and is tough to turn .... how do i adjust table? dual compound makita ls1016l miter saw

You don't adjust the table, you need to remove the table from the base and clean the surface, when you take it apart you will see what I am talking about. To do this first unplug the tool and remove the fence and kerf boards, under the kerf boards you will find a 13MM hex bolt just like on the fence, remove the bolt and lift the table off the base, clean the wear plates and lube them with a light coat of grease, on the outside rails you will see what is causing your problem, clean with a surface conditioner or fine sandpaper, lube this area also.. Make sure you do all the sides for a smooth turn, reassemble the table to the base in reverse order and install the bolt, I usually tighten all the way snug and then loosen till you can turn the table freely making sure not to loosen too much or the table will rock. Reassemble the fence squaring it to the blade and replace the kerf boards. It sounds complicated but really it is not. This is the only way you can get that metal to metal rough turning repaired.
