Product overview

Upgrade your garden power tool arsenal with this awesome 40V 12” chainsaw from Greenworks.

Note: This tool does not include a battery or charger, these must be purchased separately.

Forget about mixing fuel, pull starts, making a racket and harming the environment, with the 40V G-MAX range from Greenworks, that’s all in the past. Just juice up the battery, hit the button and you’re on task immediately.

The lightweight, ergonomic design means a well-balanced tool for superior cutting, making this saw is a great choice for pruning, while the over-mold grip handle and wrap-around handle ensure comfort, with safety taken care of by the large hand guard, chain brake and dual-switches, which guard against accidental activation.

An LED battery level indicator light makes it easier for operator to determine battery life, and the translucent oil tank offers clear view of oil reserve to ensure the 12” bar and Oregon chain are kept lubricated for sharp cutting. Tool-less chain tensioning makes for quick and easy adjustments.

How many cuts would it do (at what size branch) with a fully charged battery?
There are a heap of variables here - what type of wood, condition of wood, branch size etc. We'd encourage you to have a read of the reviews below. This will give you the best idea of what to expect for your particular application (and also on the battery you may want to look at).

Hi, does this chainsaw use the same battery as the greenworks blower vac.
Yes, all the 40V tools can use the same 40V batteries.

I am assuming I need to use a 5/32" file to sharpen the chain. Is that correct?
Yes it is.

Fantastic chainsaw for the weekend warrior

The greenworks 40v range is solid. If you've got any of the other tools, you know what to expect and this is very much the same. Very happy.

very handy little saw.

Great little chainsaw, light and easy to handle. I have a big petrol saw for the bigger jobs. My wife has had a go with my big saw but was scare witless by it. She is very comfortable with the Greenworks saw. The only negative is the bar oil tank leaks which is a nuisance.

Great to grab and go.

I really love how easy this is to take with me on farm runs. Runs well and is perfect for tidying up the track and pruning low hangers.

Brilliant little chainsaw

Was sceptical when purchasing whether it could cope with what I needed it for, but has proven to be a brilliant little chainsaw. Had no problems cutting through what I needed it to. Much quieter than the petrol based ones.
