ECHO’s CS-310ES is a lightweight, extremely well-balanced rear handle chainsaw. It has a premium grade 30.5cc Power Boost Vortex™ engine for both power and durability.

The top-mounted air filter is positioned away from dirt and debris for better filtration. Easy Start spring-assisted starting requires minimum effort – a warm engine only requires a short pull on the recoil rope. The saw has a dual-post chain brake for increased durability, while the automatic oiler delivers optimum lubrication.
The CS-310ES is an ideal tool for pruning and logging. It has guide bar options of 35 or 30cm.
