Introduction: Who the Echo CS-590 Timber Wolf Suits
The Echo CS-590 Timber Wolf is a gas chainsaw that generates significant online discussion. It is a 59.8cc saw positioned in the same displacement class as the Stihl MS 391 and the Husqvarna 460 Rancher. Owner feedback and spec-sheet analysis reveal a clear picture of its strengths and weaknesses. This review covers what works, what does not, and whether this saw is the right choice for a given budget and workload.
This is not a lab-based dyno test. The analysis here is based on reported owner experiences, published specifications, and comparative research across the category. The goal is to provide an honest, boots-on-the-ground assessment of the Echo CS-590 Timber Wolf, based on hundreds of documented cuts and common user frustrations.
Performance: Where the Timber Wolf Shines and Where It Stumbles
Power and Cutting Speed
The Echo CS-590 Timber Wolf is powered by a 59.8cc professional-grade engine. On the spec sheet, it matches the displacement of the Stihl MS 391 and the Husqvarna 460 Rancher. In reported cutting performance, this saw feels stronger than those numbers suggest. The torque curve is broad and forgiving. Owners consistently report that when burying a 20 inch bar in a 22 inch oak round, the saw does not bog down. It pulls through at a steady speed, throwing chips that look like they come from a much bigger saw.
Independent owner timing reports indicate that through a 12 inch seasoned oak log, the CS-590 makes the cut in about 4.5 seconds with a sharp chain. Through a 20 inch round, it takes about 11 seconds. These are solid numbers for a saw in this price bracket. It is not as fast as a pro-level 70cc saw, but it is close enough that most homeowners and part-time firewood cutters will never feel underpowered.
The real strength here is the power-to-price ratio. The CS-590 delivers professional-grade cutting speed for roughly half the price of a Stihl MS 462 or Husqvarna 572 XP. It will cut faster than any saw in its direct price range and will hang with saws that cost two hundred to three hundred dollars more.
Starting and Cold Weather Behavior
The digital ignition system is not a gimmick. On a cold start at 32 degrees, owners report setting the choke, pulling twice, and having the saw fire on the third pull. No flooding, no drama. The saw idles smoothly and is ready to cut within ten seconds. The pattern is consistent: one or two pulls on choke, it fires briefly, then one more pull on half choke and it is running.
This is a significant improvement over older Echo models and many competitor saws that require multiple pulls. The digital ignition adjusts the spark timing automatically, eliminating the need for a manual decompression valve or hunting for the sweet spot on the throttle. It just works.
That said, the saw does have a bit of a learning curve for users accustomed to a saw with a manual decompression button. The CS-590 does not have one. The starter cord must be pulled with authority; light pulls will not get it done. Once the rhythm is figured out, it starts every time.
Chain Tensioner: The One Annoying Flaw
The chain tensioner is the most commonly cited frustration. The side-access tensioner is easy to adjust, but after about 45 minutes of heavy cutting, the chain loosens noticeably. Owners consistently report having to stop, loosen the bar nuts, tighten the adjuster, and retighten the nuts. This happens about every other tank of fuel.
Checking the bar and chain for wear, ensuring the bar is not bent, and even replacing the stock bar with an aftermarket bar does not resolve the issue. The tensioner itself seems to back off slightly under vibration. It is not a dealbreaker, but it is a persistent annoyance. For all-day cutting, a wrench must be carried and tension checked every hour. This is a widely reported issue across owner communities, not an isolated case.
Build Quality and Value: What You Get for Your Money
Materials and Fitment
The Echo CS-590 Timber Wolf is built with a mix of metal and high-impact plastic. The crankcase is magnesium, standard for professional saws. The handle is a single-piece design with good vibration damping. The air filter cover is plastic, but it is thick and has a positive latch. The saw has been reported to survive drops from waist height onto packed snow and soft ground without cracks or damage. It feels durable, though drops onto concrete are not recommended.
The long-lasting air pre-cleaner is not just marketing fluff. In dry, dusty conditions like cutting locust, the pre-cleaner catches a surprising amount of fine particles. Cleaning it with compressed air after every two tanks of fuel keeps the main air filter nearly spotless. This is a significant factor for saw longevity, as a clean engine runs cooler and lasts longer. Echo designed this saw for use in dirty conditions.
Value Proposition
Exact prices vary by region and retailer, but the CS-590 Timber Wolf typically costs less than a comparable Stihl or Husqvarna by a significant margin. It delivers a 59.8cc saw with a 20 inch bar, a 5 year consumer warranty, and a reputation for reliability at a price that feels like a steal.
The 5 year consumer warranty is a major selling point. Echo backs their products well. For a homeowner who cuts firewood on weekends, that warranty provides peace of mind. For a professional cutting every day, the warranty is shorter (2 years), but the saw remains a good value for light commercial use.
Weight and Ergonomics
The tradeoff is weight. The CS-590 weighs about 13.5 pounds dry, without bar and chain. With a full tank of fuel and a 20 inch bar, it is over 15 pounds. That is a lot of weight to carry for hours. Compared to a lighter saw like the Echo CS-400 or a Stihl MS 250, this feels like a boat anchor after an hour of limbing.
The weight is noticeable when cutting overhead or working on a slope. Owners report getting tired faster than with a lighter saw like the Husqvarna 550 XP, which is in a similar displacement class. The Echo is balanced well, with the weight centered, but it is still a heavy tool. For those with back issues or plans for all-day felling, a lighter option should be considered.
Who Should Buy the Echo CS-590 Timber Wolf
This saw is not for everyone. Here is an honest breakdown:
- Firewood cutters on a budget: If cutting 5 to 10 cords of firewood per year and wanting a saw that punches above its weight class, this is the saw. The power per dollar is unmatched.
- Farmers and landowners: For a saw that will start after sitting in a shed for six months, this is a solid choice. The digital ignition and simple carburetor tuning make it low maintenance.
- Homeowners with big trees: For a few acres and occasional storm cleanup, the CS-590 handles anything thrown at it. The 5 year warranty is a nice safety net.
- NOT for arborists or all-day professionals: For climbing trees or cutting for 8 hours a day, the weight and chain tensioner issues will be frustrating. Spend more for a lighter, more refined saw.
- NOT for casual users: For cutting only a few branches once a year, this saw is overkill. A smaller, lighter saw or an electric model is a better fit.
Verdict: A Powerful Saw With One Annoying Flaw
The Echo CS-590 Timber Wolf is a fantastic saw for the money. It cuts hard, starts easily, and is built to last. The 5 year consumer warranty is a huge bonus. It is a reliable, powerful saw for firewood or property maintenance.
But the chain tensioner issue is a real problem that affects the user experience. It is not a dealbreaker, but it is a constant reminder that this saw is not quite as refined as a Stihl or Husqvarna. A wrench must be carried and tension checked regularly. That is the price paid for saving a few hundred dollars.
If that can be lived with, the CS-590 will reward with years of dependable service. If not, spending the extra money on a saw with a better tensioning system is the better choice. For most firewood cutters on a budget, the power and value outweigh the annoyance. Just pack a wrench.
