Description
The ECHO CS‑621SX petrol chainsaw features a 59.8 cm³ X‑Series engine with strong 3.2 kW power, reduced emissions, and professional-grade ergonomics in a lightweight 6.3 kg chassis—built for heavy-duty forestry use.
ECHO CS‑621SX Rear‑Handle Petrol Chainsaw
The ECHO CS‑621SX is a rugged, professional-grade chainsaw designed for heavy forestry work. Powered by a 59.8 cm³ X-Series engine made in Japan, it delivers excellent power-to-weight balance and ultra-low emissions while maintaining premium performance.
Powerful Performance with Low Emissions
Featuring a high-output 59.8 cm³ engine that generates approximately 3.2 kW (≈ 4.4 hp), this saw stands out with industry-leading emission standards. Despite its capacity, it remains competitively lightweight and responsive across demanding tasks.
Built for Professional Durability and Control
Weighing around 6.3 kg (dry), the CS‑621SX is engineered for sectors that demand long hours in the forest. It features ergonomic balance, side-mounted tool-free chain tensioning, and a drop-prevention bar nut system to keep service quick and reliable.
Reliable Starting & Cold-Climate Readiness
With a decompression valve start-assist system and automatic fast-idle choke, cold starts become much easier. Inertia-type chain brake, anti-icing protection, dual bumper spikes, and a rotating chain catcher further support safe and consistent use across conditions.
Clean Airflow & Reduced Maintenance
ECHO’s G‑Force engine air pre-cleaner significantly limits filter maintenance by ejecting large particles before they reach the main filter. This extends service intervals and improves uptime.
Comfort & Sound Control
Equipped with a three-point anti-vibration system, the CS‑621SX minimises operator strain during extended use. Sound pressure is rated at approximately 101.6 dB(A) at the operator’s ear, with power sound output reaching around 113 dB(A).
