Product overview

This awesome 40V pole saw from Greenworks extends up to 2.7m, so you can get to even the hardest to reach places in your backyard.

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

Discover a whole new way of working thanks to the G-MAX 40V Lithium-ion battery system, with mixing fuel, pull starts, making a racket and harming the environment all a thing of the past. Just juice up the battery and pull the trigger.

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 20cm Oregon bar and chain are kept lubricated for sharp cutting. Tool-less chain tensioning makes for quick and easy adjustments.

Safety is taken care of by the electronic chain brake and dual-switches, which guard against accidental activation, while the included shoulder strap and moulded grips make life comfortable.

Questions and answers

Can the saw be operated without the pole, that is being operated as a standard chainsaw?
No, the saw is mounted to the pole and cannot be removed. The vital running gear is in the pole as well (battery, driveshaft and trigger etc). The minimum length this can be set to is 150cm.

Can the angle of the cutting head be rotated - eg head in line with pole, or at ninety degrees?
No, the head is a fixed angle.

How long is the battery life between charges?
The recharge time is 60mins for a 2.0Ah battery. The run time really depends on how much load is being placed on the tool. Thicker woods that are denser and harder to cut will drain the battery faster - you should get approx 50 cuts on a charge, but it totally depends on application.

Hi, can this trim hedges? Or better to go for the long reach hedgre-trimmer? Thanks
We'd go for the trimmer if that's you intended use - this is more for pruning.

Is the saw gutless and slows down if you attempt to take on to big a branch, or a thick hedge? Also how long before chain needs a sharpen? Thanks, Kevin.
The best thing to do is have a read of our customer reviews to see how they're using it and what they think, but that said we're confident you'll be pleasantly suprised! Chain life depends on what you're cutting and how it's treated (keep it clean and out of the dirt etc) but you should get at least 10 hours before needing to give it a sharpen.

Green Works Pole Saw

Very impressed by this pole saw, cut's like a laser. It's impressive how much material you can limb up compared to climbing a ladder and using a chainsaw. Battery life is very good.

Pole Saw

Great machine, fast cutting. Good value as I already had the required battery and charger. chatters a bit with smaller branches due to the space between cutting surfaces of the chain. But as a whole works well.

Paul Nelson
A good product

This works really well. The pole on this is pretty sturdy and assembles easily. It’s good that it goes to two lengths as the short length is handy. It uses a bit more oil than a standard chainsaw but that’s probably good. I haven’t investigated replacement chains or blades.

Pole saw

An awesome product - goes through small branches with ease, and can tackle big logs as well. I have a stack of firewood for next year thanks to this.

Excellent addition to our Greenworks collection

Does what it says on the box. Easy to set up, easy to use, easy to adjust the length. And it has more than enough cutting power for our needs. We’ve had great fun pruning all sorts of hard to reach branches.

Greenworks Pole Saw G-MAX 40V Li-Ion 2.0Ah Kit (Purchased on 1 Sep 2023)

The saw would be improved by the addition of some teeth adjacent to the chain bar. That is common in other such chain saws and would help stop the jitters when cutting. The extension is not telescopic. It uses a fixed-length insert. The web page claim, "Tool-less chain tensioning makes for quick and easy adjustments" is not true. A tool is required and it is not supplied. A caution. The chain bar oil reservoir empties well before the battery needs re-charging. Check the oil level frequently, when in use. I consider the tool to be appropriate value for the cost. Especially as - in my past annual hiring experience - such a tool is only used a few times-a-year.

Handy around the garden

Meets expectations. Useful around the garden. Be realistic regarding what the saw can handle.

Fantastic tool

It cuts branches vert easily and fast. Not too heavy. The battery charge lasts for many cuts. One of the best tools I’ve ever used in the garden. Highly recommended.
