Cordless Chainsaw Review – GreenWorks G-MAX 40V

GreenWorks G-MAX 40V Li-Ion 16-Inch Cordless Chainsaw

Greenworks Tools chainsaws and other yard work products are very popular these days and for good reason. They are moderately priced, available everywhere and are a good value. The Greenworks G-Max 40V 16″ cordless chainsaw is their top of the line saw and a popular choice for medium to heavy duty chores.

Greenworks has a wide range of outdoor landscaping tools that are battery compatible so its a nice choice if you want to begin building your collection of yard tools including pressure washers! But they aren’t a tool company in the sense that Black & Decker is or Makita so your non-yard tools will be limited. But let’s get to the dirt on this saw…

The Basics

The G-MAX 40V is a lightweight at 6.9 pounds dry, which is usually a big consideration for those looking to go cordless. Maintenance is a breeze with tool-less adjustments to the chain on its 16″ bar and an automatic oiler system. Its big claim to fame are its brushless motors, which promise 30% more torque, 70% less vibration and a longer life. It features a standard chain brake and includes a 4AH Battery and Charger and you are ready to go out of the box. The business end of the GreenWorks G-MAX 40V has a heavy duty 16-inch Oregon bar and chain, .0375 chain pitch, safety chain brake, and metal bucking spikes. The 16″ bar is the largest in its class and can handle large crosscuts up to 30″.



This saw is what we call an earner. It performs great on logs of virtually any size. It’s lightweight make it perfect for small jobs but its power and size means that it can handle any job you throw at it. The brushless motors do deliver on some promises: good torque and lower vibration. Their design means that you will likely never wear them out and they will at least outlast the rest of the saw. We also found this to be one of the quieter saws in our tests and one that your neighbors will appreciate. Overall the saw workmanship feels a little lower quality than something like the Makitas but it doesn’t feel cheap and the performance was excellent. Greenworks claims you can cut a cord of wood on one battery….hmmm, maybe they are getting a bit creative there! But in general, the battery output is good. It’s worth mentioning that some users report chain tension problems, although we didn’t experience any, at least not so far.

The Bottom Line
The GreenWorks G-MAX 40V is a hard worker and a great value at its price point. It is suitable for medium to heavy work and we appreciate its lightweight. Although you may never need it, the 16″ bar is impressive and adds more versatility to this already capable machine. The brushless motors make a noticable difference in performance and comfort. Although Greenworks may not have the pedigree of a Makita, at this price its a well-performing bargain.
