ABSTRACT:
A guard for a portable chain saw is provided that will prevent injury from saw "kick-back" and will assist in preventing injuries from a moving saw blade. The chain saw guard can be easily adapted to conventional chain saws by the use of ordinary hand tools and includes a motor housing bracket and blade bridge, which is slidably directed along the saw blade by a pair of attached rods that are slidably mounted to the housing bracket. A slotted blade guide bar receives a bridge guide to stabilize a vertical bridge component, and a resilient spring returns the bridge to its original, extended posture along the blade.
