摘要： Front feet are provided at a lower part of a cutting-machine main body via a foot holder. Furthermore, a slider positioned on a front side relative to the front feet is provided at the lower part. When a workpiece to be cut is to be cut by a blade, the cutting-machine main body is tilted so as to let the blade go down. When the cutting-machine main body is tilted, a state where the front feet are in contact with the workpiece is switched to a state where the slider is in contact with the workpiece. Then, by moving the cutting-machine main body forward while sliding the slider on the workpiece, the workpiece is cut by the blade. In the cutting operation, the front feet can get away from the workpiece. Therefore, damage of the front feet can be prevented, and the running cost can be suppressed.
摘要翻译： 前脚通过脚架设置在切割机主体的下部。 此外，在下部设置有位于相对于前脚的前侧的滑块。 当待切割的工件要被刀片切割时，切割机主体被倾斜以使刀片下降。 当切割机主体倾斜时，前脚与工件接触的状态切换到滑块与工件接触的状态。 然后，通过在将滑块滑动到工件上的同时向前移动切割机主体，通过刀片切割工件。 在切割操作中，前脚可以远离工件。 因此，能够防止前脚的损伤，能够抑制行驶成本。

摘要： A power circular saw includes a circular saw blade rotated by a motor, a plate-like base, and a protection cover. The base includes a front end, a rear end, and an opening located between the front end and the rear end. The opening receives a portion of the circular saw blade. The protection cover covers a saw-tooth line of the circular saw blade above the base. The protection cover includes a guide portion that is located at a position corresponding to a plane or the saw-tooth line of the circular saw blade and projects toward the front end of the base.

摘要： A switch mechanism includes a support structure and an electric switch having an activator moveable between a first position where the electric switch is ON and a second position where the electric switch is OFF. A cam is connected to a first actuator, moveably mounted on the support structure, so that movement of the first actuator results in movement of the cam. A bar is connected to a second actuator, moveably mounted on the support structure, so that movement of the second actuator results in movement of the bar. The cam engages the activator so that movement of the cam by movement of the first actuator results in the activator moving between its two positions. The bar engages the activator so that movement of the bar by movement of the second actuator results in the activator moving between its two positions.
