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

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.

more capable than it looks.. and sounds

I bought this polesaw on the back of buying the 16" 40V chainsaw (So i use it with the larger 4.0Ahr battery, which give a good amount of cutting time). It is surprisingly grunty, and handles large green branches 150mm in diameter with relative ease, and in silence... well OK, maybe not silence, but it is certainly much quieter than the petrol equivalent. great addition to the rechargeable tool kit. Only downside is that it feels quite top(saw end) heavy, but with the battery mounted right on the base end of the pole, you couldn't really get better balance.using the supplier shoulder strap helps.

Great pole saw

This is my second pole saw and the 40V system is excellent for garden tools. It cuts every quickly and the charge lasts a long time. The auto oil feed works well but you must keep the feed area clean or it will clog. A brilliant saw.

What a brilliant product. Have purchased the GreenWorks Chainsaw and blower previously and they are fantastic. Going to the battery is certainly easier and easier especially for the smaller jobs although I have used all of them quite hard too.

For garden tools it's probably one of the best purchases I have made. One charge gives loads of use and I'm still amazed at the size of the limbs it will cut through. I have a petrol driven pole saw and it looks like it's destined for the scrap heap.

Great tool for the arsenal

The pole saw is the latest addition to my greenworks tool shed and I’ve been very impressed with its performance. I’ve been using to trim cryptomeria shelter trees so far and this thing absolutely chews through it. The ability to take out pole lengths also makes it very maneuverable. Battery performance is impressive as with the other greenworks tools. Drops a star for being a little awkward at full length and the fit of the arm strap. However a bit more use should get me used to it. Thanks Trade Tested
