Echo CS-621SX Petrol Chainsaw

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 cm≥ 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 cm≥ engine that generates approximately 3.2 kW (‚âà 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).
