About the ECHO CS-621SX Petrol Chainsaw

A best-in-class heavy-duty chainsaw designed for professional users

The ECHO CS-621SX is a rear handle chainsaw from their X Series range designed for commercial operators and local authorities, for medium and large felling applications. It is the best in its class and is packed with features to increase the productivity of professional operation. Choose from an 18, 20, or 24 inch bar and chain.

Fitted with a top quality ECHO petrol engine

Equipped with a premium grade, low emission ECHO 59.8 cc petrol engine outputting 3.2 kW, the Japanese-quality engine gives excellent cutting performance; despite its power, the saw is relatively light in weight (dry weight 6.2 kg) and therefore easy to handle. A decompression valve encourages faster and almost effortless starting. The anti-icing system stops the carburettor from freezing in colder months making the chainsaw suitable for year-round use.

Comfortable and safe operation

The heavy-duty aluminium handle features a rubber grip for secure grip and reduces vibration in the hands. A rotating plastic chain catcher protects the user from injury and also prevents damage to the chain. An inertia-type chain brake is an important safety feature. Dual bumper spikes allow for great precision and better control.

Included features keep maintenance time to a minimum

Engine exposure to dirt and debris is minimised thanks to G-Force engine air pre-cleaner, for less maintenance and longer-lasting performance. Dropout prevention nuts cannot be lost during maintenance. Side access to the chain tensioner allows for easy chain adjustment. A tool-less air filter cover makes accessing the air filter simple. Large fuel and oil caps facilitates easy filling, whilst the translucent fuel tank makes checking the fuel level effortless.


A 2 year professional/5 year domestic warranty with ECHO is included, we will register the machine. T&Cs apply.
