Personal Experience

The first time I engaged the start mechanism on the CS-590, I immediately noticed the difference. The decompression valve allowed for a smooth, almost effortless start, even during those frosty early morning jobs. It was a stark contrast to the grueling, often temperamental, starts I’ve dealt with in previous models.

Once the chainsaw sprang into action, the power the 59.8cc, 2-stroke engine delivered was formidable. The CS-590 had a voracious appetite for even the most stubborn hardwoods. Yet, for all its bite, it navigated through softer woods with an unexpected delicacy, making clean, precise cuts every time.

What truly struck me was Timberwolf’s surprising fuel efficiency. While I’ve used chainsaws with similar power before, none have managed to optimize fuel use as efficiently. The digitally controlled carburetor, which automatically adjusts the fuel/air mixture, clearly played a major role in this. It’s not just a boon for my operating costs; it’s a nod towards a more eco-friendly tool.

The Timberwolf CS-590’s versatility was another standout feature. The saw accommodated bar lengths ranging from 18 to 27 inches. This meant I could seamlessly transition from felling towering trees to handling smaller pruning tasks without needing to swap tools.

ECHO clearly made user safety a priority in the design of the CS-590. The chainsaw’s dual-post chain brake system proved its worth on more than one occasion, rapidly halting the chain during kickback events. This critical feature gave me confidence during operation and a greater sense of security.

Additionally, the anti-vibration handle was a literal comfort. I could feel a marked reduction in the vibrations transferred to my hands and arms, which resulted in less fatigue at the end of a long workday. The handle also offered a firm, secure grip, reducing the chance of the saw slipping out of control.

The CS-590 was not just user-friendly in operation, but also in maintenance. The easy-access, two-piece air filter made what was typically a cumbersome task, a far more manageable one. This practical design element helped reduce downtime, allowing me to spend more time doing what I needed to – cutting wood.

My experience with the ECHO Timberwolf CS-590 has been nothing short of exemplary. It’s a perfect storm of power, adaptability, and efficiency. For professionals like myself or homeowners with substantial woodcutting needs, this chainsaw is an invaluable ally. It’s a tool that has earned its place in my toolkit, and I expect it to remain there for many years to come.

Unleashing the Power

At the heart of the Timberwolf CS-590 is a formidable 59.8cc professional-grade, 2-stroke engine.

Furthermore, the engine design ensures smooth, consistent power, reducing common problems like stalling or power loss during demanding jobs.
