Abstract
A chop saw pivotably mounted for movement between a raised rest position and a lowered operational position, having a motor driven saw-blade rotatably supported about a shaft, with a saw housing partially encasing the saw-blade and a swinging blade guard which covers the exposed segment of the saw-blade when the saw is in the rest position. When the saw is lowered to its operational position, a linkage system comprising four effective levers and four hinges clears the blade guard, thereby exposing the saw blade to the work piece. To accommodate changing the saw blade while the saw-unit is in its rest position, the effective length of one of the levers can be temporarily reduced, thereby clearing the blade guard from the exposed section of the saw blade. This provides easy access to the saw-blade to be changed.
