The Echo CS-621SX is a heavy-duty professional chainsaw and the advanced, low-emission successor to the legendary CS-620SX. Built in Japan for commercial forestry workers, professional loggers, and demanding contractors, it combines high-displacement power with an agile, lightweight frame.
Key Specifications
Engine Displacement: 59.8 cc professional-grade, 2-stroke
Power Output: 3.2 kW (4.4 ps)
Dry Weight: 6.3 kg (Without bar and chain)
Guide Bar Lengths: Compatible with 18", 20", and 24" (45 to 60 cm) options; typically supplied with a 20" (50 cm) bar
Fuel Tank Capacity: 0.65 Litres
Chain Oil Tank Capacity: 0.30 Litres
Saw Chain Pitch: 3/8"
Standout Professional Features
High-Output 59.8cc Engine: Generates massive torque and cutting speed while complying with strict modern low-emission standards.
G-Force Engine Air Pre-Cleaner: Centrifugally ejects dust and debris before it reaches the main air filter, drastically reducing maintenance intervals during intense shifts.
Decompression Valve & Fast-Idle Choke: Engineered for smooth, low-effort pull starts and reliable cold-weather ignition.
Rugged Magnesium Chassis: Balances professional-grade durability with reduced overall weight to minimize operator fatigue.
Field-Ready Conveniences: Equipped with a side-access chain tensioner, drop-prevention bar nuts, a rotating chain catcher, and a built-in anti-icing shutter valve for freezing conditions.
