Echo CS-310ES Chainsaw is a lightweight, extremely well-balanced Rear handle petrol chainsaw. It has a premium grade 30.5cc Power Boost Vortex engine for both power and durability (stage 2 compliant low emission engine). A newly designed "thumb-press"™ locking cylinder cover stays secure even under extreme use. 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. Comes with a guide bar of 12”/30cm.
