The new ECHO CS-4510ES rear-handle chainsaw has a 45cc two-stroke stratified scavenging engine, and a power-to-weight ratio that makes it more powerful yet lighter than previous models, with output of 2.3kW and a dry weight of just 5.0kg.
The Stage II emission compliant engine is one of ECHO’s new engine platforms. The two-stroke has a piston-operated scavenging system in which a layer of fuel-free air is created between the burnt charge in the combustion chamber and the fresh charge in the crankcase. The buffer reduces the fuel laden losses during the cycle.
This translates into a chainsaw that generates more torque to cut faster and more efficiently through harder wood. Other features include the new air filter design that shields the engine from dust intake, the drop-out prevention nuts, translucent fuel tank, and the ES Easy Start system.
It has a two-year professional warranty or five-year domestic warranty.
