A gasoline or motor saw is a mechanical chain saw driven by an internal combustion engine, usually a two-stroke. The motor and the cutting tool of the saw are connected by a transmission system in the form of a gearbox. Chainsaw engines can vary in power, design, and fuel tank capacity. The cutting tool of the saw is an all-in-one chain (sleeve-roller) moving along the guide rail, on which the saw teeth are located. Ensuring its immobility and safety at idle is carried out by a self-coupling mechanism with a centrifugal principle of operation. In conditions of a sharp increase in the load on the engine (for example, when the chain is jammed), this mechanism is capable of breaking (or reducing to normal) the transmission torque to the tire. Modern models also have a braking mechanism that instantly stops the cutting tool when the tire bounces in the direction of the sawyer, in case of breakage and other unforeseen circumstances.The modern market offers its customers saw blades of three classes: domestic, semi-professional, and professional. The power of household models does not exceed 2 kW, and the weight is 4 kg. The teeth of such saws are low-profile (shallow cutting depth), which is aimed at reducing vibration during operation, and the narrow and short tire (11-13 inches) is aimed at reducing the likelihood of saw blades bouncing during improper use. Their motor life is designed to be used for an average of 20 hours per month (approximately 40 minutes per day). This is the most common class of chainsaws, they are most often purchased by owners of private homes and summer residents.For semi-professional saws, the power ranges from 2 to 3 kW, with a weight of 4 to 6 kg. They have a longer tire (14-16 inches). The motor life of semi-professional chainsaws is designed for daily operation lasting about 4 hours.As for professional models, their power ranges from 3 to 6.4 kW. They are capable of sawing the hardest, frozen and polluted wood, for this their teeth are reinforced with carbide soldering. These chainsaws use both low-profile and high-profile chains. At the same time, the strong vibration of high-profile and high-pitch circuits is combated as follows: with a large step, a low profile is used, and if the step is smaller, the profile is made high. In the manufacture of professional saws, durable and wear-resistant materials are used, and their motor life is 1300 - 2000 operating hours, so 8 hours of continuous operation per day is the usual norm. These models of saws are mainly purchased by organizations professionally engaged in harvesting and processing wood.
