Remove the mag from the rifle and now take a spent (NOT LIVE ROUND) 30-06 case, insert it in the chamber and drop the bolt on it make sure there is pressure on the 30-06 case by the bolt. Now turn the rifle upside down and using a punch, gently knock out the extractor that is located towards the front of the bolt and a little off center towards the roller. When the extractor is removed turn the rifle right side up cover the reciever with a rag (to prevent and catch any springs from flying off) pull back on the op rod and remove the 30-06 case. Reassemble in the reverse order. Hope that helps.
