ECHO CS‑4310SX Rear‑Handle Petrol Chainsaw – 16″ (40 cm) Bar
The ECHO CS‑4310SX rear-handle petrol chainsaw delivers true professional-grade performance in a remarkably lightweight frame. Optimised for heavy-duty limbing and medium-duty felling, it combines a 42.9 cm³ engine with superb ergonomics for efficient productivity across demanding forestry tasks.
Industry-Leading Power-to-Weight Ratio
Powered by a 42.9 cm³ two-stroke engine, this saw delivers approximately 2.3 kW (≈ 3.1 hp) while weighing only 4.3 kg (dry). The result: exceptional balance between cutting capacity and mobility—making it one of the most potent and portable saws in its class.
Advanced Clean-Air Filtration System
The CS‑4310SX features ECHO’s centrifugal separation “dust-free” system—a scaled-down version of the CS‑7310SX system—which removes debris before it reaches the main filter. Paired with a pleated automotive-style filter, this system significantly reduces cleaning frequency and extends maintenance intervals.
Pro-Level Ergonomics & Control
Designed for user comfort and fatigue reduction, this saw includes a heavy-duty aluminium handle with rubber grip and a three-point anti-vibration system. Safety features include a momentary-engine restart switch, rotating chain catcher, and drop-prevention nuts. A translucent fuel tank allows quick fuel checks.
Smooth Start & Easy Maintenance
ES‑Start® starter assist and automatic fast-idle choke ensure reliable starting with minimal effort. The side-access chain tensioner and flip lever caps make chain adjustments and refuelling fast and convenient—even with gloves on.
