How to get my EU started again?

Midway through a court it seemed to Flickr as if the current had been cut off and then back on again very quickly when I finish the cut and tried to start it again. Nothing almost as if there is no power . I have checked the fuse that is okay there is power at the switch at the handle, but that is all I can find out. I do not know enough to start taking it apart without some idea of what I'm looking for if anyone can help, I would appreciate it
