Size: 16" (4.0Ah) Gen 2
I have two friends that have a the older version of this saw – which is still available on Amazon. (Model 20312). I purchased this saw on their recommendation but went with the newer Gen 2 version (Model CS40L412). The saw is primarily used at a hunting property cutting trees that range from 3 inches to 10 inches. I’ve had the chance to use it twice. (I have two batteries and used the saw for approximately 3 hours each day.) It does a great job. I’m very pleased with the saw. Battery life is good – but not great. If you cut much you’ll want one or two extra batteries. Observations - 1) The earlier model of the saw (Model 20312) has a “tool free chain tensioning system” which is a very nice feature. I wish that feature was on the Gen 2 (Model CS40L412). The Gen2 has a traditional screw to tension the chain. 2) I'm not sure it has a high quality chain. I ordered an Oregon chain that I'll install in the near future. I will still use my gas chainsaw on larger trees and larger stumps. Only complaint. The nuts that hold secure the bar loosen up from time to time. Luckily, they are designed so they will not drop out. So you’ll want to keep an eye on this issue if you purchase this particular saw.

First time in my life using a chain saw. Works great!! Can’t wait to use it more and also have my dad test it out! I was looking for a cheap chainsaw like the smaller trimmers which lead me to discovering this after researching into products learning those mini chainsaws don’t work as well as something like this. I got the 16 inch saw with battery and charger included Assembly was easy I did it myself Had to buy the oil and chain lube because it didn’t come with a starter bottle for that like I thought. Which we delayed me 3 weeks from being able to test this out. The batteries in this chainsaw match the batteries with my greenworks brushless push mower and my leaf blower/mulcher combo!! So far I love all the greenworks products I have and I can’t wait to try more over time as I need them. I like the safety features with the saw cover, also that you flip the black part in front of your top hand to lock the saw, the thumb safety then the trigger. Knowing I don’t have to do anything extra to start or shut this saw down is huge for me! No mixing oil and gas either. I searched into this saw before buying. YouTube had a great video from a guy comparing this 16 inch 4.0ah to the 18 inch 8 whatever numbers for that battery and they pretty much were comparable for the demonstration he did. So I’d you’re interested and want to make sure it’s the right fit for you check the reviews and also YouTube for a video longer in action. The guy explained alot and also compared this chainsaw to a regular gas chainsaw which really helped me since I had never used a chainsaw before. Only Con would be the chain adjuster tool does not attach to this chainsaw so you have to keep it in a place you know where it’s at. I did not have to adjust my chain at all when using it today for a few quick jobs. Me having 3 batteries that fit this chainsaw means I can get a lot of use out of it in one day if ever needed Along with that I have the 3 batteries to extend my usage needed on the mower or leaf blower/mulcher as needed. So my tip is; if Battery and Brushless motors are something you’re interested in see what other potential “tools/yard “machines” you may want in the feature and see what batteries they take so you can have extra batteries added in when buying units with a battery and charger included. If I have any issues I will update my review but this is not a daily need for me, just an as needed for clean up in the yard or limbs that fall down occasionally and need cut up to burn. Another reminder I learned is you can not force the cut with this chainsaw As a normal gas chain saw you can not force the cut either.

I used this thing a while back to cut up a bunch of small trees and it worked great!! Only downside was the chain would loosen up after a while, but I could have been a little rough with it too? (This is the first chainsaw I have ever purchased in my life) It also came with a battery that would work in my snow blower so that's pretty cool! Very easy to use too!

Wow!!! Amazing cutting power in an easy to use chainsaw! Worked with several friends trimming trees and like one of them use my new 16” Battery powered chainsaw and he was totally impressed on the power and how fast it could cut through even large branches. I used it the first time to cut down 5 trees and the biggest was a 22” diameter tree that it took down with ease. I shopped around and like at a lot of Battery chainsaws, and this was by far the best value!

I bought the 40V 16" model. So I have a few good and a little bad to report on this. The bad first. The packing was messed up on mine and the plastic blade guard was severely damaged to the point of being unusable. That was the only negative! Now to the good. This is easy to use, pretty light and the battery is top notch I take it camping with me and it will easily last the entire weekend. also the charger is small and lightweight and I can charge it with my little Jackery 240 solar generator power bank if needed Now this might sound odd but I store it upside down, that way the oil doesn't leak out of it and make a mess. Some people have complained about it leaking oil everywhere when they store it, so if you either empty the oil tank after every use or store it upside down that will keep it from leaking. Mine doesn't have the quick adjust for the chain tension so it can be a bit finicky but as long as you have used older style chainsaws this will feel comfy to you and in reality I wonder about those new fangled plastic adjuster knobs and how sturdy they are. I like having the darn metal bolt that I know is going to hold the tension where I put it. It is easy to clean and the battery slides in from the top and locks in place so even if you use it upside down "not recommended" the battery stays put. Now there is a slight lag between you squeezing the trigger and the blade starting like about 1.5 seconds. first time I used it I thought it was broken I squeezed the trigger 4 or 5 times and nothing, then I just squeezed and held it and presto. So squeeze the trigger, hold it for a couple seconds and it will start up. The battery has a 4 section indicator light showing the power remaining so you can have a basic idea of the remaining power. The feel of the saw is well balanced once the battery is in it. it's very front heavy without the battery. Charging is a bit slow but that is better for the battery and will extend it's life. It took me a couple of hours to charge it from one bar left on the battery. Overall I would buy this again.

An electric chainsaw is brilliant to begin with. Forget small engine headaches. The greenworks chainsaw works great. I cut through 12" limbs with no problems. It would cut bigger, but that is the biggest I have. Greenworks customer service is the best. Three months before the warranty expired, the chainsaw developed a problem. After diagnosing over the phone, Greenworks decides to just send me a new saw. I have other Greenworks tools that work equally as well as the chainsaw. Great product, great company.

It cut fine at first, and the battery seems good - but who knows how good, since it is sitting in my garage before I get up the energy to send the lousy thing back. The problem is it threw the chain after a few hours of work. No problem. I've owned a dozen chainsaws in my life (but not this manufacturer). That's when I found out how cheaply it is put together. The chain tightening mechanism is cheap plastic. It will never keep the proper tension on a train. It will throw a chain easily. You will overtighten it. The chain will get messed up and you'll keep buying chains because you'll think it's your fault. Save your money. This is a piece of garbage.

You will NEED a 13mm wrench and flat head screwdriver everywhere you go as the chain is poor quality and needs constant adjustment. Battery life is quite good, 40v is all you will need unless you have a very large job. I suspect a chain upgrade would make this saw much better. Chain flew off several times as I did not check chain tension often enough which slightly bent a few links that caused a problem trying to get the links reseated into the bar and on the drive wheel.
