I'm on my 4th dw788,I highly recommend taking your dw788 apart and re grease every bearing(some need to be pressed out) with valvoline synthetic grease.I wore out my first and gave away and my friend is happy as a bird with a french fry with it.I told him keep it on 5 or less with the speed control and you'll get long life from it.i have too new dw788's for back up and am using another dw78 that i re greased that's wore out but tight as a drum now from the grease.
