Radial arm DW 721 saw. Starting problem.
Any ideas why when I switch it on it judders making a buzzing noise and then starts the motor in reverse? I’ve tried the reset button, sometimes it works sometimes not. I’ve not come across this before and don’t have a clue where to start, I know that electric motors will spin in either direction but why would it suddenly start doing so? Help please! Cheers Paul
