All my Dw788's had not a scratch on them,All had the same story,couple hours or less use.All had a price i couldn't refuse from $100 to $250.All started to knock shortly after the amazing kevin started knocking down tall wood piles to short ones.Is there a common denominator in saws i buy or is it me?I'm sure they just need to be re greased with synthetic grease.I do tend to wear gloves after scrolling long hours from the heat build up,lol Lucky you ! I need to get into my stack and regrease them an press out two bearings per machine
