ECHO CS-400 Chainsaw: Features, Specs, Price & More

As a seasoned chainsaw dealer, I’ve had the privilege of working with a wide range of chainsaws, but one model that never fails to impress both professionals and homeowners alike is the Echo CS-400. Echo, a brand renowned for its quality and innovation in outdoor power equipment, has truly outdone themselves with this exceptional chainsaw. In this in-depth review, we’ll explore the Echo CS-400, its various versions, features, specifications, pricing, and why it’s a standout choice for your cutting needs.

Different Versions

There are primarily two versions of the Echo CS-400 chainsaw: the standard Echo CS-400 and the Echo CS-400-18. Both models share the same engine and many core features, but the CS-400-18 comes with an 18-inch bar and chain as opposed to the standard 16-inch on the base model. The choice between the two largely depends on your specific cutting requirements. The 18-inch bar provides a longer reach, making it ideal for larger trees and tougher jobs, while the 16-inch version is more maneuverable and suited for lighter to moderate tasks.


One of the standout features of the Echo CS-400 chainsaw is its robust and reliable 40.2cc 2-stroke engine. This engine is designed to deliver exceptional power while maintaining fuel efficiency and reduced emissions, ensuring compliance with environmental regulations. With a maximum engine speed of 12,800 RPM, you can trust the Echo CS-400 to slice through even the toughest of woods with ease.

  1. G-Force Engine Air Pre-Cleaner: This innovative technology extends engine life by reducing the amount of debris and dust that enters the air filter. Cleaner air means fewer engine breakdowns and longer operational life.
  2. Digital Ignition System: The CS-400 is equipped with a digital ignition system for quick and easy starts. You can rely on it to fire up reliably even in cold weather.
  3. Easy Access Chain Tensioner: Maintenance is a breeze with this chainsaw. The tool-less, easy-access chain tensioner allows you to adjust the chain quickly, ensuring optimal cutting performance.
  4. Automatic Oiler: The automatic oiler keeps the chain lubricated for smoother cutting and reduced friction. This feature not only prolongs the life of your chain but also ensures you get precise and efficient cuts every time.
  5. Anti-Vibration System: Working with a chainsaw for extended periods can be tiring, but Echo has integrated an anti-vibration system into the CS-400. This significantly reduces user fatigue, making it more comfortable to operate for longer durations.
  6. Safety Features: Safety should always be a priority when working with chainsaws. The Echo CS-400 includes a chain brake that stops the chain in case of kickback, increasing user safety.
  7. Clean Air Filtration System: Echo’s filtration system ensures that clean air reaches the engine, reducing wear and tear and improving overall performance.
  8. Translucent Fuel Tank: A clear fuel tank makes it easy to monitor fuel levels, so you can refill at the right time without interruptions.

The Echo CS-400 was competitively priced, offering great value for its performance and features. Prices can vary depending on your location and any promotions or discounts available at the time of purchase. You can typically expect to invest between $299 to $349 for the Echo CS-400 and slightly more for the Echo CS-400-18 due to its larger bar size.


Now, let’s get down to the real question: How does the Echo CS-400 perform in the field?

First and foremost, this chainsaw is a workhorse. Whether you’re a professional arborist or a homeowner tackling occasional tree maintenance, the CS-400 delivers consistent and dependable performance. The 40.2cc engine generates enough power to handle a wide range of cutting tasks, from trimming branches to felling medium-sized trees.

One of the standout qualities of the Echo CS-400 is its ease of use. The digital ignition system ensures that starting the chainsaw is a breeze, even in challenging weather conditions. The automatic oiler keeps the chain lubricated, reducing friction and ensuring a smooth cutting experience. Plus, the easy-access chain tensioner means you can make adjustments on the fly, optimizing cutting efficiency without the need for additional tools.

The anti-vibration system deserves special mention. Echo has done an excellent job in reducing vibration levels, making it comfortable to use the CS-400 for extended periods. Reduced vibration means less strain on your hands and arms, which is crucial for both safety and user comfort.

Maintenance is straightforward, thanks to the thoughtful design of the CS-400. Routine tasks like cleaning the air filter, refilling fuel, and checking the chain tension can be done quickly, allowing you to spend more time cutting and less time on upkeep.

Safety is paramount with any chainsaw, and Echo has incorporated a chain brake into the CS-400 to mitigate the risk of kickback incidents. While no chainsaw is entirely foolproof, this feature adds an extra layer of protection for users.

On the downside, the Echo CS-400 is not the lightest chainsaw on the market, especially when opting for the CS-400-18 with the larger bar. This can be a consideration if you need a highly portable and maneuverable saw. However, the added weight does contribute to its durability and stability during cuts.

In terms of fuel efficiency, the CS-400 is commendable. The 13.9 fl. oz. fuel tank provides ample runtime, and the efficient engine design helps conserve fuel. This not only saves you money on fuel costs but also reduces your environmental footprint.


While the Echo CS-400 is a strong contender, it’s essential to consider alternative options based on your specific needs and preferences:

  1. STIHL MS 170: The Stihl MS 170 is a lightweight, entry-level chainsaw ideal for homeowners. It offers excellent reliability and ease of use, making it a great choice for occasional cutting tasks.
  2. Husqvarna 450: If you’re seeking more power for heavier-duty work, the Husqvarna 450 is a solid choice. With a 50.2cc engine and a range of bar lengths available, it’s well-suited for professional use.
  3. Makita XCU03PT1: For those who prefer the convenience of cordless tools, the Makita XCU03PT1 offers a 36V battery-powered chainsaw with impressive cutting performance and minimal maintenance.


In conclusion, the Echo CS-400 chainsaw is a remarkable piece of outdoor power equipment that caters to a broad range of users, from homeowners to professionals. Its blend of power, ease of use, and thoughtful features make it a top contender in its category. The choice between the standard CS-400 and the CS-400-18 depends on your specific cutting needs, with both models delivering reliable performance.

While there are other chainsaws on the market, the Echo CS-400’s reputation for durability, ease of maintenance, and user-friendly design sets it apart. Whether you’re looking to maintain your property or tackle demanding forestry work, the Echo CS-400 is a dependable companion.
