The locking pin is used to secure the saw head in the lowered position when transporting (or storing) the saw. The pin moves in and out of the pivot bracket, allowing you to lock (or unlock) the hinge. It's possible to shear the pin if something heavy is dropped on the saw (when the hinge is locked). If this occurs, the pin should be replaced.
