Hello, I am new to the forum and of course I have a question. The bearings in my Sears router, Model# 315.17491, were bad and I changed them. Putting it back together I found the springs in the safety switch were bent, and then I lost one. I was looking for a cut sheet of the switch couldn't find on. I couldn't get the switch to lock in the unlocked position. It ran fine if I manually held the switch in the ON position.
