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.
