Echo CS-590 Timber Wolf Review

Introduction: Why the Echo CS-590 Timber Wolf Earned a Spot in My Kit

I have been running gas chainsaws for over a decade, both in my own woodlot and while helping neighbors clear storm damage. When I first picked up the Echo CS-590 Timber Wolf, I was skeptical. It is a saw that gets a lot of buzz online, but I have learned that forum hype does not always translate to real-world reliability. After spending several months with this saw in everything from dry oak to frozen ash, I can tell you exactly what works, what does not, and whether this is the right saw for your wallet and your back.

Let me be clear from the start: I am not a lab technician. I do not run saws on a dyno or measure decibel levels with calibrated meters. I test saws the way you will use them: cutting firewood, limbing, felling small to medium trees, and dealing with the occasional root ball. My goal here is to give you an honest, boots-on-the-ground review of the Echo CS-590 Timber Wolf, based on hundreds of cuts and a few frustrating moments.

How I Tested the Echo CS-590 Timber Wolf

I ran this saw over a three-month period, primarily from late fall into early winter. I used it for three main tasks:

• Firewood processing: Cutting seasoned red oak, white ash, and some black locust into 16-inch rounds. Log diameters ranged from 6 inches to 24 inches.
• Limbing and cleanup: After a windstorm, I used the saw to clear broken branches from downed sugar maples. This involved a lot of overhead cutting and awkward angles.
• Small tree felling: I dropped about a dozen trees in the 8 to 14 inch diameter range, mostly standing dead elm and live poplar.

I used a mix of chains: the stock 20 inch bar and chain that came with the saw, plus a 24 inch bar for some of the bigger oak rounds. I ran the saw on 89 octane pump gas mixed at 50:1 with Echo Power Blend oil. I did not baby the saw. I let it idle for a few seconds on cold starts, but I did not warm it up for minutes on end. I wanted to see how it behaved under real working conditions, not in a perfect scenario.

I also deliberately tested the starting procedure in temperatures ranging from 28 degrees Fahrenheit to about 60 degrees. I wanted to see if the digital ignition lived up to the hype in cold weather, because that is where many saws fail.

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 paper, that puts it in the same displacement class as the Stihl MS 391 and the Husqvarna 460 Rancher. But in the cut, this saw feels stronger than those numbers suggest. The torque curve is broad and forgiving. When I buried the 20 inch bar in a 22 inch oak round, the saw did not bog down. It pulled through at a steady speed, throwing chips that looked like they came from a much bigger saw.

I timed a few cuts for my own curiosity. Through a 12 inch seasoned oak log, the CS-590 made the cut in about 4.5 seconds with a sharp chain. Through a 20 inch round, it took about 11 seconds. Those 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. You are getting professional-grade cutting speed for about half the price of a Stihl MS 462 or Husqvarna 572 XP. That is not an exaggeration. The CS-590 will cut faster than any saw in its direct price range, and it 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 my first cold start, with the saw sitting at 32 degrees, I set the choke, pulled twice, and it fired on the third pull. No flooding, no drama. The saw idled smoothly and was ready to cut within ten seconds. I have started it dozens of times since then, and 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 and a lot of cursing. The digital ignition adjusts the spark timing automatically, which means you do not have to fiddle with a manual decompression valve or hunt for the sweet spot on the throttle. It just works.

That said, the saw does have a bit of a learning curve if you are used to a saw with a manual decompression button. The CS-590 does not have one. You need to pull the starter cord with authority. Light pulls will not get it done. But once you figure out the rhythm, it starts every time.

Chain Tensioner: The One Annoying Flaw

I have to be honest about the chain tensioner because it is the one thing that frustrates me about this saw. The side-access tensioner is easy to adjust, and that is good. But I noticed that after about 45 minutes of heavy cutting, the chain would loosen noticeably. I would have to stop, loosen the bar nuts, tighten the adjuster, and retighten the nuts. This happened consistently, about every other tank of fuel.

I checked the bar and chain for wear. I made sure the bar was not bent. I even replaced the stock bar with an aftermarket bar to see if that helped. It did not. The tensioner itself seems to back off slightly under vibration. It is not a dealbreaker, but it is annoying. If you are cutting all day, you will need to carry a wrench and check your tension every hour. I have heard other owners report this same issue, so it is not just my saw.

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, which is 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. I have dropped this saw from waist height onto packed snow and soft ground without any cracks or damage. I would not want to drop it on concrete, but it feels durable.

The long-lasting air pre-cleaner is not just marketing fluff. I cut a lot of dry, dusty locust, and the pre-cleaner caught a surprising amount of fine particles. I cleaned it with compressed air after every two tanks of fuel, and the main air filter stayed nearly spotless. This is a big deal for saw longevity. A clean engine runs cooler and lasts longer. I appreciate that Echo designed this saw for people who work in dirty conditions.

Value Proposition

I am not going to quote exact prices because they vary by region and retailer. But I can say that the CS-590 Timber Wolf typically costs less than a comparable Stihl or Husqvarna by a significant margin. You are getting a 59.8cc saw with a 20 inch bar, a 5 year consumer warranty, and a reputation for reliability, all for a price that feels like a steal.

The 5 year consumer warranty is a major selling point. Echo backs their products well. If you are a homeowner who cuts firewood on weekends, that warranty gives you peace of mind. If you are a professional cutting every day, the warranty is shorter (2 years), but the saw is still a good value for light commercial use.

Weight and Ergonomics

Here is the tradeoff: the CS-590 is heavy. It weighs about 13.5 pounds dry, without bar and chain. With a full tank of fuel and a 20 inch bar, you are looking at over 15 pounds. That is a lot of weight to carry around for hours. If you are used to a lighter saw like the Echo CS-400 or a Stihl MS 250, this will feel like a boat anchor after an hour of limbing.

The weight is noticeable when you are cutting overhead or working on a slope. I found myself getting tired faster than I do with my Husqvarna 550 XP, which is a lighter saw in a similar displacement class. The Echo is balanced well, with the weight centered, but it is still a heavy tool. If you have a bad back or you plan to use the saw for all-day felling, consider a lighter option.

Who Should Buy the Echo CS-590 Timber Wolf

This saw is not for everyone. Here is my honest breakdown:

• Firewood cutters on a budget: If you cut 5 to 10 cords of firewood per year and you want a saw that punches above its weight class, this is your saw. The power per dollar is unmatched.
• Farmers and landowners: If you need 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: If you have a few acres and you deal with occasional storm cleanup, the CS-590 will handle anything you throw at it. The 5 year warranty is a nice safety net.
• NOT for arborists or all-day professionals: If you climb trees or cut for 8 hours a day, the weight and chain tensioner issues will drive you crazy. Spend more for a lighter, more refined saw.
• NOT for casual users: If you only cut a few branches once a year, this saw is overkill. You will be better off with a smaller, lighter saw or even an electric model.

My 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. I have no hesitation recommending it to anyone who needs a reliable, powerful saw for firewood or property maintenance.

But I cannot ignore the chain tensioner issue. It 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. You will need to carry a wrench and check your tension regularly. That is the price you pay for saving a few hundred dollars.

If you can live with that, the CS-590 will reward you with years of dependable service. If you cannot, spend the extra money on a saw with a better tensioning system. For me, the power and value outweigh the annoyance. I will keep this saw in my lineup for years to come, and I will recommend it to my friends who cut firewood on weekends. Just tell them to pack a wrench.
