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.

Q:
Can I sharpen this myself?
A:
Yes it can, you just need to ensure that the chainsaw sharpener is matched to the pitch and gauge of the chain. Chain gauge = 0.05mm Chain pitch = 3/8" We also sell replacement chains for this pole saw, it is listed as 'Greenworks 40V Pole Saw 8" Replacement Chain'

Q:
Can the saw be operated without the pole, that is being operated as a standard chainsaw?
A:
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.

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

Q:
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.
A:
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.

Does what it promised

Great piece of kit, easy to assemble and does a brilliant job on trimming those high branches

Great pole saw

Great pole saw that has allowed me to trim high branches in my back yard. I was impressed with the width of branches it allowed me to cut.

Glad we bought this

Easy to assemble, chain simple to tighten, poles straightforward to put together. The only aspect we don't enjoy is filling the oil reservoir, the hole is too narrow and the 'transparent/translucent' gauge is very opaque so difficult to see how much oil is in there. In operation, and at full extension it is quite heavy and I personally could not use it for more than 20-30 minutes in that configuration. At the medium extension, it's nice to use, a bit bottom heavy in balance but that's to be expected. As we only need this tool 3-4 times a year, it does the job for us. Battery holds its charge well and the charger gets it fully charged very quickly. Cutting thru wood is fast and efficient, no problems here. As others have noted, the saw will leak a small amount of oil when not in use, but it is not excessive. All in all, a good purchase thus far.

Works as expected

Great powerful little long tool

Easy to handle and use. I had to fell a chestnut tree in a narrow space and cut all branches off first. In no time and no ladder needed the job was done. Love it!

Greenworks 40V Pole Saw 8" Skin

Minimal assy required, quite grunty & the 8" bar will chop through some sizable branches & small stumps My only gripe is the balance of the assembled pole saw, the saw head end is quite heavy compared to the battery end & reaching up to cut those higher limbs either requires reasonable upper body strength or short bursts of activity depending on your level of fitness.

No more cords Taranaki
Great power, quality product

Really pleased with this purchase. A really solid and secure product and so impressed with how sturdy it is and how quickly it gets through tree limbs. Would have no hesitation recommending this!

Pole saw awesome

Yes I recommend this product.

I am 77 years of age and have no problem operating this pole saw. I am a first time buyer of a Greenworks product and am impressed with the quantity of the pole saw. I use it for around 4 hours and have never had to charge the battery. As with all chainsaws you need to empty the oil tank before storage.
