HELP!!! Ryobi 524h won't run

Hi,
I am running a Ryobi 524H and after a clean up one day, it gave me the
error code E-1.
Now it will inch but won't actually run.
Does anyone have any ideas.
Please asap

 

It is probaly a swich in one of the safty covers

 

I have went through all the covers but the thing I did stumble on was that if I wiggle the stop button and it hits a right spot it will come on, I don't know if that would be a short somewhere or what.
It does that on any of the stop buttons also.
Thanks for getting back to me, if you think of anything else, please let me know.

 

adjusting the knife out of limits, return to the original position.

 

Thank you to all that responded to my problem. It turns out it was the safety cover switch was stuck slightly on but not enough to turn the light on to say that's where it was. Found it by a fluke bumping it, you couldn't tell it was pushed in at all.
Thanks again for all the response.
