Echo CS 400 Review – The Best Affordable Chainsaw By Echo!

This Echo chainsaw is the one to start with if you’re a beginner. Because you’ll be just starting up with the use of chainsaws, you wouldn’t need a big expensive chainsaw to get your hands used to. Even if you aren’t a beginner, but still haven’t gotten your hands on just the right saw for your household, this chainsaw is going to be the best you’ll own. 

Echo CS-400 chainsaw is a mid-range saw that boasts a 40.2 CC Power Boost Vortex engine to provide strength and high performance, a G-Force Engine Air Pre-cleaner to extend motor life, a smart ignition system, and the i-30TM technology to reduce starting efforts by 30%. 

Moreover, the chainsaw is highly rated by chainsaw users because it has a powerful engine, a simple start-up system, and a lightweight design.

This article contains our detailed review of the saw, including its features, specifications, and pros and cons as well. 

Is Echo a Good Chainsaw Brand?

We would personally recommend Echo to anyone and everyone. Out of all the chainsaw brands that exist, there is no doubt that Husqvarna and Stihl are the best chainsaw brands in the world. 

However, not everybody can afford them, and my personal opinion is that you don’t really need them unless you’re a professional logger whose job is to deal with the biggest trees for which he’ll be needing a heavy-duty saw. 

And so, for the people who just need to carry out their around-the-house cutting tasks in the backyards or gardens, there isn’t a need to own a highly expensive and super powerful saw. After Husqvarna and Stihl, Echo is one of the top chainsaw brands and its products are highly reliable and durable as well. 

Echo CS-400 – What Separates it From its Competitors?

In my option, because CS-400 is a mid-range saw, it suits the needs and preferences of most users. It isn’t an entirely small saw nor is it a huge heavy-duty saw. It just proves to be the perfect saw for light-duty tasks such as cutting, trimming, and pruning branches or even cutting small trees.

Also, if maintained properly, the chainsaw goes a long way. It’s a highly durable saw that you can totally rely on for your work. But above all, I think it’s the price factor that makes it a winner at the end of the day. You won’t really find such good chainsaws in this price range and so, it makes itself a standout among its competitors.

Variable Speed Adjustments

The Echo CS-400 chainsaw has variable speed adjustments that allow you to adjust the cutting speed to suit your needs. The chainsaw features a throttle control that enables you to adjust the speed of the engine, allowing you to cut through different types of wood with ease. 

This feature is especially useful when cutting through thick or dense wood, as you can increase the cutting speed to make the job faster and more efficient. The variable speed adjustments also help to reduce kickbacks, making the chainsaw safer to use.

Variable Speed Adjustments

Quiet Operation

One of the notable features of the Echo CS-400 chainsaw is its relatively quiet operation compared to other chainsaws in its class. This is due to its sound-reducing technology, which helps to minimize the noise produced during operation. 

The chainsaw’s engine is designed to run smoothly and efficiently, producing less noise while still providing powerful cutting performance. The reduced noise level makes the Echo CS-400 ideal for use in residential areas where noise regulations may be in place, as it is less likely to disturb your neighbors.

Minimized Kickbacks

The Echo CS-400 chainsaw is designed with an anti-vibration system and a reduced kickback bar and chain, which helps to minimize the risk of kickbacks during use. The anti-vibration system reduces the amount of vibration transferred to the user’s hands and arms, making it more comfortable to use for extended periods of time and reducing the risk of fatigue and injury. 

The chainsaw also features a reduced kickback bar and chain, which helps to prevent the chainsaw from jumping back toward the user in the event of a kickback.


The Echo CS-400 chainsaw is designed to be eco-friendly by incorporating a two-stroke engine that is compliant with EPA Phase 2 and CARB Tier 3 emissions regulations. This means that the chainsaw produces fewer emissions than many other chainsaws on the market, making it a more environmentally conscious choice. 

Additionally, the chainsaw is designed to be fuel-efficient, which reduces the amount of fuel consumed and minimizes the number of emissions produced during use. The automatic oiler system also helps to reduce emissions by ensuring that the chainsaw is properly lubricated without requiring excess oil.
