McCulloch "Timber Bear" 600 series how to properly re-set chain brake?

I was trying to properly place my bar on the chain tightening screw, and wasn't paying attention to the location of that spring when I turned the thing upside down. Of course, that spring fell out, and I don't know where it goes. Can someone, anyone please show or tell me how to use that spring to properly set my chain brake?
