BUY Chainsaws

A chain saw (or chainsaw) is a portable mechanical saw, powered by electricity, compressed air, hydraulic power, or most commonly petrol.

Most chain saws require two sources of lubrication. Like most two-stroke engines, the engine is lubricated by its fuel, which contains about 2–5% oil (depending on the oil used) dissolved in the fuel. Separate chain oil or bar oil is used for the external lubrication of the bar and chain.

Despite safety features and protective clothing, injuries can still arise from chain saw use, from the large forces involved in the work, from the fast-moving, sharp chain, or from the vibration and noise of the machinery.

Dramatic improvements, chain saw 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.

Chain saws have almost entirely replaced simple man-powered saws in forestry. They come in many sizes, from small electric saws intended for home and garden use, to large "lumberjack" saws
