phenning Posted March 19, 2012 Report Share Posted March 19, 2012 Hi I recently got a 7770 radial arm saw, but have been unable to use it. each time i turn it on the blade starts turning and it trips the power. If i start it without a bade attached it runs fine. as soon as i fit a blade it trips the power again. any thoughts, might it be the starting relay or a issue with the dual voltage motor. I have measured the voltage in my workshop, 230V and the breaker that trips is a 20A breaker. Quote Link to comment Share on other sites More sharing options...
