Abstract
Portable circular saws are taught that may include a base and a saw unit pivotally coupled to the base. The saw unit may have a circular saw blade that is adapted to laterally pivot relative to the base. A stopper may be provided to allow an operator to selectively stop the saw unit at a second pivot angle that is between a first pivot angle and a third pivot angle. Preferably, the stopper may have an operative position and a non-operative position. In the operative position, the saw unit can pivot from the first pivot angle to the third pivot angle without stopping at the second pivot angle. In the non-operative position, the saw unit can pivot between the first pivot angle and the second pivot angle. A first stopper may be provided to permit the saw to be selectively stopped at a small angle pivot position (e.g. 0°) before a minimum pivot angle (e.g. −5°). A second stopper may be provided to permit the saw to be selectively stopped at a large angle pivot position (e.g. 45°) before a maximum pivot angle (e.g. 50°).
