ECHO CS-501P X-Series Chainsaw Review

ECHO CS-501P Chainsaw Caters To High-Performance Needs Without Bloated Weight

Recently we had the opportunity to help our friend Eli Mosley out on the ranch to deal with some downed oak trees. We had some success in the past using other battery-powered chainsaws, but we wanted to test out something in the 50cc class to get our work done quicker and more efficiently. The ECHO CS-501P chainsaw seemed right up our alley, so we got our hands on one and got to work.


  • Outstanding performance for the 50c class
  • Incredibly lightweight for the 50cc class
  • Easy starting
  • Easy filter access


  • Ignition switch doesn’t return to the on position automatically
  • No onboard scrench storage

ECHO CS-501P X-Series Chainsaw Performance

This chainsaw is part of ECHO’s X-Series, which emphasizes higher performance, and it definitely lives up to that reputation here. Its 50.2cc engine helped us make quick work of a downed oak tree with the 20-inch Pro-Lite bar and 20LXP chain confidently shredding through the hardwood.

Note: If needed, this saw also comes with a 16- or 18-inch bar if your needs are more suited for those sizes.

ECHO’s G-Force engine air pre-cleaner helps keep extend the filter life, which leads to more time between maintenance intervals. Accessing the filter is a tool-free process, too. All you have to do to access it is loosen the knob on the housing above the handle

Along with this is a digital ignition system and a decompression valve for an easy start-up.

ECHO CS-501P X-Series Chainsaw Design Notes


CS-501P chainsaw limbing

As for this chainsaw’s design, ECHO’s X-Series chainsaw focused on shaving off some pounds. The CS-501P chainsaw has a dry weight of just 10.6 pounds, making it the lightest 50cc chainsaw currently available in North America. This lightweight design helps you achieve excellent cutting performance with lower fatigue.

Chain Tensioning

Chain tensioning is also made easy on this chainsaw. You start by loosening the two bar nuts about half a turn each. Then, it’s as simple as supporting the bar in one hand and using the scrench to adjust the tensioner with the other. After tightening the bar nuts back up you’re good to start cutting.

The bar nuts are captive, too, so you don’t have to worry about losing them when you need to access the chain sprocket or change out the bar or chain.

Ignition Switch

One aspect we’re not too keen on is the ignition switch. On this model, it doesn’t automatically return to the “On” position after shutting the engine off. This might not seem like that big of a deal, but many chainsaw users cite this issue as a major pain point. Luckily, ECHO has addressed it, and the newest chainsaw models have an automatic return design.

Additional Highlights

  • Beefy metal bucking spikes
  • Intertia-activated chain brake
  • Adjustable automatic oiler
  • Ergonomic aluminum front handle

Retail prices for this chainsaw can range from $499.99 to $519.99, depending on which bar length you prefer. The brand backs your purchase with a 5-year consumer warranty or a 1-year commercial-use warranty.

The Bottom Line

ECHO’s CS-501P X-Series chainsaw has the performance to cut through hardwoods like butter. That coupled with its low weight makes it an absolute pleasure to use and very easy to manage. If you’re looking for a 50cc chainsaw, you’d have a hard time finding a better combination of weight and power than this one.
