Hi, I recently found a spring on the floor under my saw. I don't recognize it, and it's not obvious where it belongs. Anybody know? I have not tried using the saw since finding the spring since it could be something important. It is 3/8" diameter by 3-1/4: long, plus a 3/8" closed loop on both ends. ***I tried to post a photo but it would not upload... Thanks for any info.
