Product overview

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

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.

Hi there, could you please how long will the battery last when using the chainsaw
It's difficult to put an accurate number on it as it will vary depending on how much energy is required (eg. cutting scrub vs cutting a larger log), however 25 minutes is an approximate guide.

I've got the older model of this chainsaw and I see the battery shape has changed, will my old version of the battery still fit in this newer model (old ones are still g-max 40v, it's just the shape I'm thinking about).
Yes they are still compatible, the battery connection didn't change, just superficial design elements.

How long to charge battery and can batteries be overcharged?
This will take approx 60 mins to charge, as long as the charger is working correctly then no, although we recommend unplugging the charger and removing battery is they are not being used for an extended period.

Awesome product love it

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.

Does everything I need it to

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.
