ECHO CS-4310SX Professional Chainsaw – 18" Bar (X-Series)
Redefine agility and cutting speed with the ECHO CS-4310SX 18-Inch Chainsaw. Holding the prestigious title of the most powerful and lightest chainsaw in its displacement class, this professional-grade mid-sized saw is a true marvel of Japanese engineering. As a premium member of ECHO’s X-Series, it is powered by an aggressive 42.9cc 2-stroke engine delivering 2.3 kW of power, yet weighs a truly astonishing 4.3 kg (dry). This provides the absolute best power-to-weight ratio in its class, ensuring extreme maneuverability and comfort without ever compromising on raw felling power.
The CS-4310SX is packed with heavy-duty features designed specifically to increase professional productivity and reduce maintenance downtime. It boasts an industry-leading centrifugal separation dust-free system—a scaled-down version of the massive filtration system found in ECHO's flagship CS-7310SX. This system actively ejects dust and debris before it can even reach the automotive-style air filter, massively extending service intervals. Complete with a heavy-duty aluminum handle, a 3-point anti-vibration spring system, and drop-prevention nuts, this ultra-lightweight forestry chainsaw is the ultimate weapon for professional arborists and demanding landowners.
