Automatic Chain Saw

It uses two physical principles: circular motion (inertia) and friction. The chainsaw clutch is made of two main parts that are separate when the engine idles slowly: The drive shaft, shoes, and spring. The drum, sprocket, and chain.The circular blade rotates at high speed. The saw blade is fixed on an arbor, and the user needs to move the machine to make the desired cut. One can adjust the angle of the blade by moving the machine to change the cutting angle.
