ABSTRACT:
A circular saw has a housing enclosing a motor for driving an output shaft about an axis of rotation. An upper bladeguard is immovably secured to the housing and has a rear wall defining an arcuate slot. A rectangular base plate is pivotally attached at its forward portion to the saw housing for swinging movement about a pivot axis parallel with the output shaft and disposed substantially forwardly thereof. An arcuate bracket arm has one end thereof connected to the rear of the base plate. A fastening element is mounted on the other end of the bracket arm and is received within the slot in the upper bladeguard. The operator may adjust the base plate by grasping the fastening element and moving the same along the slot in the upper bladeguard.
