The most powerful and lightest chain saw in its class.
The ECHO CS-4310SX is a professional grade, mid sized chain saw suitable for a wide range of applications, including felling. With an extremely light weight and durable frame and a powerful 42.9 cm³ 2-stroke engine it provides the best power to weight ratio in its class. This means you get extreme maneuverability and comfort without compromising on power. The industry leading, centrifugal separation dust free system is a scaled down version of the filtration system found in the CS -7310SX.  This system uses centrifugal forces and an automotive style filter to ensure your engine and internal components stay free from dust and debris, massively reducing the need for maintenance.
Weighing just 4.3 kg with a 42.9 cm³ engine that provides 2.3 kW power the CS-4310SX has the best power to weight ratio in its class.
Centrifugal separation dust free system massively reduces the need for maintenance by removing dust and debris in stages before air even reached the automotive style air filter.
