I pressed the green On button on my K3 but didn't hold it in long enough....it stopped then hummed momentarily and now will not respond when the On button is pushed. This has occurred before, but after waiting for a few minutes it's always started eight up. I've waited 15 mins and nothing. The Hammer manual that came with the saw is useless for trouble shooting. Any thoughts on what I may have done to the motor or starter electronics? Is there a fuse or reset switch that I should check? I see no obvious access to the motor.
