Our take on the Greenworks CS40B210 40V 12-Inch Chainsaw

The Greenworks CS40B210 is a cordless 12-inch chainsaw built on Greenworks' 40V battery platform. It comes with a 2.0Ah battery and charger, a 12-inch bar, automatic oiling and tool-free chain tensioning, and it starts with a push button instead of a pull cord. It suits light yard work: limbing, pruning, and cutting small logs or firewood. Against gas saws it is quieter and needs no fuel mixing, but it has less power and a shorter bar than gas or larger cordless saws, so it is not a felling tool.

What reviewers say

Owners of this class of Greenworks 40V saw generally find it easy to start and handy for pruning and small logs. The common complaints are short runtime on the included battery and limited power in larger wood.

What people mention
  • BatteryMixedRuns long enough for pruning and light limbing but drains fast when cutting thicker wood.
  • PowerCriticisedOwners say it bogs down in larger logs and is best kept to branches and small cuts.
  • StartupPraisedPush-button starting is repeatedly called easy, with no pull cord or fuel mixing.
  • WeightMixedManageable for short jobs but tiring when held up for long trimming sessions.
  • ChainMixedTool-free tensioning is liked, though the chain needs tightening and sharpening often.

Questions and answers

Is this saw good for cutting firewood?
For small logs and branches, yes. The 12-inch bar and 0.73 hp motor struggle with large or dense logs, so it is a limbing and pruning saw rather than a firewood workhorse.
How long does the battery last?
Greenworks rates it at up to 40 minutes of runtime and up to 50 cuts per charge with the 2.0Ah battery. Expect less in thick or green wood.
Does it come with a battery and charger?
Yes. The box includes the 2.0Ah 40V battery, a charger, the bar and chain, a scabbard and the manual.
Does it use the same batteries as other Greenworks tools?
Yes. It runs on the Greenworks 40V platform, so the battery works in other 40V Greenworks tools and larger batteries fit this saw.
Do I need to mix fuel or pull a cord?
No. It is battery powered and starts with a push button, so there is no gas, oil mixing or pull cord.
How do I tension the chain?
Use the tool-free tensioning knob on the side of the saw. Check tension before each use and after the chain warms up.
Where is the Greenworks CS40B210 40V 12-Inch Chainsaw cheapest?
At Walmart, for $157.99, as of our latest check.
