ABSTRACT:
A chain saw guard which includes a two-part base structure mountable on the housing and chain guide plate of a chain saw, and a pair of subframes pivotally mounted on the base structure. One subframe includes a pair of lateral frame members positioned on opposite sides of the chain guide plate and a third frame member positioned over the upper run of the chain, and the subframe is pivotable upwardly about an axis positioned near the saw housing to a position exposing the upper run of the blade. The other subframe is constructed similarly to the first but is positioned to protect and guard the lower run of the chain, and is mounted on the base structure to pivot downwardly about an axis positioned near the saw housing.
