About the ECHO CS-420ES Petrol Chainsaw
High-Performance Chainsaw for Professional Demands
The ECHO CS-420ES is a professional-grade petrol chainsaw built to deliver consistent performance in demanding environments. Powered by a robust 40.2 cc two-stroke engine, it provides the strength needed for a wide variety of cutting applications. This commercial-grade engine ensures reliable output throughout extended working hours, making it an ideal choice for professional foresters, farmers, and landscapers. Whether felling medium-sized trees, cutting firewood, or handling site maintenance, this chainsaw offers dependable performance and lasting durability.
Built for Comfort and Extended Use
Engineered for all-day use, the CS-420ES features an ergonomic design that balances power with operator comfort. Its lightweight construction, at just 4.6 kg (dry weight), makes it easy to handle without sacrificing durability. Dampened vibration levels help reduce operator fatigue during longer cutting sessions, allowing you to work more efficiently. The thoughtfully designed layout also enables smooth manoeuvring, giving you excellent control even in tight or awkward spaces.
Safe and Reliable Operation
Safety is a key feature of the CS-420ES, with its inertia-activated chain brake offering immediate protection during kickback. This automatic safety mechanism stops the chain instantly, significantly reducing potential injury risks. The chainsaw is also equipped with an anti-icing system that channels warm air from the engine to the carburettor. This prevents freezing during cold weather, ensuring reliable operation in all seasons. These features combine to make it a dependable tool in both warm and cold working conditions.
Easy Starting and Simple Maintenance
Starting the CS-420ES is almost effortless thanks to ECHO’s Easy Start technology. This system reduces the pulling force required, making engine ignition smooth and predictable. A tool-less air filter cover allows quick access to the air filter, even while wearing gloves. This convenient design makes regular maintenance easier and less time-consuming. The side-access chain tensioner allows precise adjustments without difficulty, ensuring your chain remains in optimal working condition. Together, these features minimise downtime and keep the saw performing at its best.
Exceptional Cutting Performance
The CS-420ES is available with a 38 cm (15-inch) guide bar, offering the ideal balance between reach and control. Its saw chain pitch of 0.325 inches and gauge of 0.058 inches deliver efficient, aggressive cutting performance. The high power-to-weight ratio enhances productivity, allowing you to work quickly without excessive strain. The chainsaw’s low-emission engine also meets environmental standards, reducing its environmental footprint while maintaining high cutting efficiency. This makes it a versatile choice for felling, snedding, and bucking medium-sized trees.
Conclusion: A Professional Chainsaw You Can Trust
The ECHO CS-420ES combines high power, excellent manoeuvrability, and advanced safety features in one durable package. With its easy starting system, low vibration levels, and exceptional cutting capability, it’s designed to help you work efficiently and comfortably.

Tony –
I needed t do do some tree trimming and wanted a reliable light chainsaw that I could use high up a tree and this echo fitted the bill. I have a husqvarna 266 SE but it was to heavy. The Echo is brilliant and you can use it all day without fatigue. I favour Echo tools they come with a 5 year domestic or two year industrial guarantee and are reasonably priced for what you get
