Rated 4.5 out of 5 by 262 reviewers.
Rated 5.0 out of 5.0 by Very nice chain saw I had a Poulan chain saw for 10 years that finally died. I purchased this saw and it has worked great. I've cut a lot of wood with it and starts and runs great. I read from some pro operators that if I used 89 fuel and added an ethanol stabilizer to the fuel that this newer engines will run great and it has. The hand fatigue after 8 hours of cutting is much less my previous chain saw. I wished I would have bought this saw years ago instead of struggling with Poulan. I also purchased an 18" PowerSharp bar, chain and stone that helps so much with keeping the chain sharp. June 23, 2014
Rated 5.0 out of 5.0 by This chainsaw rips Adjusted the carb right out of the box. Put in pre-mix fuel and bar chain oil. Pumped primer once and it started. I went through 1 tank of fuel. Saw worked like a champ right out of the box. Very happy after reading some of the bad reviews. January 15, 2013
Rated 5.0 out of 5.0 by Perfect size and weight / easy maintenance This is the second CS-400 I have owned. My son was needing a saw so I gave him my original saw and didn't think twice about buying another one for myself. I use the saw for cutting and trimming trees on my property. The size is perfect for what I use it for. Chain adjustment quick and easy. I also own Echo brand string trimmer and power pruner. They start every time and perform well. April 26, 2015
