Docupton Posted November 7, 2012 Report Share Posted November 7, 2012 I'm experiencing something very strange with my ex21, I can be quite happily cutting away when suddenly the motor speeds up, usually for less than a minute and then returns to normal before doing it again a few minutes later, very disconcerting when doing fine cuts. Can anyone tell me why this should be happening or more importantly how to cure it, any help would be appreciated, thanks. Quote Link to comment Share on other sites More sharing options...
Travis Posted November 8, 2012 Report Share Posted November 8, 2012 Sounds like the speed controller is on the fritz. You might have to replace it. I'd shoot the manufacturer and email and see if they've heard of the problem and know of any fixes. Quote Link to comment Share on other sites More sharing options...
