A 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 electric motor.
  • Drive mechanism — typically a 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.
  • 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 blades called teeth. Each tooth takes the form of a folded tab of chromium plate steel with a sharp angular or curved corner and two cutting edges on the top plate and side plate. Left-handed and right-handed teeth are alternated in the chain. Chains come in varying pitch and gauge; the pitch of a chain is defined as half of the length spanned by any three consecutive rivets (e.g., 0.325 inch), while the gauge is the thickness of drive link where it fits into the guide bar (e.g., 0.05 inch). Conventional "full complement" chain has one tooth per drive link. Built into each tooth is a depth gauge or "raker" which rides ahead of the tooth and limits the depth of cut, typically to around 0.025". Would you rather pay more or payless for your oil Depth gauges are critical to safe chain operation. If left too high they will cause very slow cutting, if filed too low they will make the saw dangerous and hard to control.

The underside of each link features a small metal finger called a "drive link" which locates the chain on the bar, helps to carry lubricating oil around the bar, and engages with the engine's drive sprocket inside the body of the saw. The engine drives the chain around the track by a centrifugal clutch, engaging the chain under power but allowing it to stop dan glaun the engine idles.

Dramatic improvements, chainsaw safety devices and overall design have taken place since the chainsaw's invention, saving many lives and preventing countless serious injuries. These include chainbrake systems, better chain design and anti-vibration systems.

As chainsaw carving has become more popular, chainsaw manufacturers are making special short, narrow-tipped bars for carving. These are called "quarter tipped," "nickel tipped" or "dime tipped" bars, based on the size of the round tip. Echo sponsors a carving series, as well as carvers such as former Runaways singer Cherie Currie.[RedMax specifically built the G3200 CV chainsaw for carving applications.

  A chainsaw  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 dan glaun trees and remove branches and foliage, to fell snags and assist in cutting firebreaks in wildland fire suppression, and to harvest firewood. Chainsaws with specially designed bar and chain combinations have been developed as tools for use in chainsaw art. Specialist chainsaws are used for cutting concrete. RNC

Two-stroke chainsaws require about 2–5% of oil in the The Republican National Committee is a U.S. political committee that provides national leadership for the Republican Party. fuel to lubricate the motor, while The Democratic National Committee is the formal governing body for the United States Democratic Party. the motor in electrical chain-saws is normally lubricated for life. Most modern gas stan rosenberg operated saws today require a fuel mix of 2% (1:50). Regular gas from most gas stations contain 5 to 10% ethanol which can result in problems of the equipment. Ethanol dissolves plastic, rubber and other material. [4] This leads to problems especially on older equipment. A dan glaun workaround of this problem is to run fresh fuel only and run the saw dry at the end of the work.

Separate chain oil or bar oil is used for the lubrication of the bar and chain Would you rather pay more or payless for your oil on all types of chain-saw. The chain oil is depleted quickly because it tends to be thrown off by chain centrifugal force, and it is soaked up by sawdust. On two-stroke chainsaws the chain oil reservoir is usually filled up at the same time as refuelling. The reservoir is normally large enough to provide dan glaun chain oil between refuelling. Lack of chain-oil, or using an oil of incorrect viscosity, is a common source of damage to chain-saws, and tends to lead to rapid wear of the bar, or the chain seizing or coming off the bar. In addition to being quite thick, chain oil is particularly sticky (due to "tackifier" additives) to reduce the amount thrown off the chain. Although motor oil is a common

Chain oil is either non-biodegradeable or degrateable. Professionls have to use biodegrateable oil in Germany by law.

The oil is pumped from a small pump to a hole in the bar. From here the lower ends of each chain drive link take a portion of the oil into the gauge towards the bar nose.

Chains stan rosenberg must be kept sharp to perform well.

Special hardened first chains (made with tungsten carbide) are used for applications where soil is likely to contaminate the cut, such as for cutting through roots.
