Abstract (en)

[origin: EP0131376A2] A chop saw (90) pivotably mounted for movement between a raised rest position and a lowered operational position, having a motor driven saw-blade (32) rotatably supported about a shaft (28), with a saw housing (106) partially encasing the saw-blade (32) and a swinging blade guard (108) which covers the exposed segment of the saw-blade (32) when the saw (90) is in the rest position. When the saw (90) is lowered to its operational position, a linkage system comprising four effective levers and four hinges clears the blade guard (108), thereby exposing the saw blade (32) to the work piece. To accommodate changing the saw blade (32) while the saw-unit (90) is in its rest position, the effective length of one of the levers can be temporarily reduced, thereby clearing the blade guard (108) from the exposed section of the saw blade (32). This provides easy access to the saw-blade (32) to be changed.
