Introduction:

Chain saw is a portable mechanical saw, powered by electricity, compressed air, hydraulic power, or most commonly a two-stroke engine. It is used in activities such as tree felling, limbing, bucking, pruning, by tree surgeons to fell trees and remove branches and foliage, to fell snags and assist in cutting firebreaks in wild land fire suppression, and to harvest firewood.

Construction:

chainsaw consists of several parts.

              Engine — almost always a two-stroke gasoline (petrol) internal combustion engine, usually with a cylinder volume of 30-120 cm3 or an electric motor.

              Drive mechanism — typically a centrifugal clutch and sprocket.

              Guide bar — an elongated bar with a round end of wear-resistant alloy steel typically 16 to 36 inches in length. An edge slot guides the cutting chain. Specialized loop-style bars, called bow bars, were also used at one time for bucking logs and clearing brush, although they are now rarely encountered due to increased hazards of operation.

              Cutting chain — Usually each segment in this chain (which is constructed from riveted metal sections similar to a bicycle chain, but without rollers) features small sharp cutting teeth. Each tooth takes the form of a folded tab of chromium plated steel with a sharp angular or curved corner and two cutting edges, one on the top plate and one on the side plate.
