ECHO CS-621SX Petrol Chainsaw

Heavy-Duty Chainsaw for Professional Performance

The ECHO CS-621SX is a professional-grade rear handle chainsaw built for serious commercial and forestry work. Designed for medium and large felling applications, it delivers the power, precision, and durability needed for demanding environments. Part of ECHO’s X Series range, it is widely regarded as best in class for professional productivity. Available with an 18, 20, or 24-inch bar, it offers flexibility to suit different cutting requirements.

Premium ECHO Engine for Maximum Power

At its core is a 59.8 cc low-emission petrol engine producing an impressive 3.2 kW of output. This Japanese-engineered powerhouse delivers exceptional cutting performance without unnecessary weight, making it efficient and comfortable to handle. Weighing only 6.2 kg (dry weight), it maintains excellent balance for prolonged use. A decompression valve ensures smoother, quicker starts, while the anti-icing system keeps the carburettor operating reliably during cold weather, enabling year-round use.

Comfort and Safety in Every Cut

The heavy-duty aluminium handle is fitted with a rubber grip, reducing vibration and improving operator comfort. This design minimises strain, allowing for longer, more controlled cutting sessions. A rotating plastic chain catcher enhances user safety while protecting the chain from damage during operation. The inertia-type chain brake provides vital protection by instantly stopping the chain when required. Dual bumper spikes add stability and improve control when making precise cuts, even in challenging conditions.

Maintenance Made Fast and Simple

ECHO has designed the CS-621SX to minimise downtime with practical, time-saving maintenance features. The G-Force engine air pre-cleaner removes dust and debris before it reaches the engine, extending service intervals. Dropout prevention nuts ensure essential components remain secure and avoid accidental loss during servicing. Side-access chain tensioning allows quick, accurate adjustments, keeping the saw working at peak performance. A tool-less air filter cover enables easy cleaning and replacement without extra tools. Large fuel and oil caps make refilling straightforward, while the translucent fuel tank provides a quick visual check of levels.

Built for Reliability and Long-Term Use

The CS-621SX combines ECHO’s engineering expertise with rugged build quality for consistent performance under heavy workloads. Whether felling large trees or handling commercial forestry work, this saw delivers the power and precision professionals expect. Its combination of advanced safety features, user comfort, and reduced maintenance requirements makes it a reliable partner for demanding cutting tasks.
