I know this might sound like a crazy question,,but I up graded tables saws from a delta 7491rs to a grizzly go833p which is 220,,i went to start it and pushed the start button and it would not start,,needless to say it wasn't pluged up,,as soon as I plugged it up the saw started from when I tried to start it before I noticed it being unplugged,,the dewalt saw never did this,,,the motor would not engage or lock into a start mode before it was pluged up,,,seems kinda dangerous,,is this the way Its supposed to be,,any thoughts or infro would be a blessing,,thank you
