Greenworks 80V 10" Brushless Cordless Polesaw (Great For Pruning and Trimming Branches / 75+ Compatible Tools), 2.0Ah Battery and Charger

Trimmed 6 large live oak trees that had *never* been trimmed before, and cut limbs as large as 8 inches. I did not count precisely, but would estimate based on how tired I was and how much my back ached that in 4 hours I cut about 100 limbs before the battery gave out. I did use up/dull one chain completely, and the second one (I had bought separately when I bought the pole saw) got kinda slow on the second (backup battery I bought separately when I yadd-yadda) battery, and I realized I had let the oil reservoir run out. It is so quiet and easy to use/run, that you have to be very watchful and check the window on the side showing the amount of oil left. When getting a replacement chain be very careful to get not just 10" but also one with 56 nodes/links and 0.50 inch depth. I bought several at a big box hardware store and they did NOT work, irritating since I was out in the boonies with no close-by location to get a replacement. That was great, because I was plumb wore out, even though there was 2 out of 3 LEDs lit on the battery power life indicator. I'm 6'6" tall, so my reach with the 10 foot pole is really good. I do think the shoulder sling should be more adjustable as to WHERE on the pole it is located, since I have long arms (my draw length on an Olympic Recurve Bow is 32") and the sling doesn't really work for me. but the pole itself is well balanced and for the really high high limbs using it one-handed was fine. I will complain that the safety button you have to depress with your thumb before you can engage the actual on switch to start cutting was pretty irritating at times, refusing to depress until I lowered the pole, put two thumbs on it, and then started the motor before raising it up to cut the limbs off the oaks. Final comment, save the rubber "washers" that protect the wire from the battery to the cutting head at each of the two joints (yes, a little assembly is required to use it and then dis-assemble to put it back in the box for storage. ) If you don't re-insert those rubber protector washers in the end of the aluminum tube the edge might eventually cut into the electrical wire. This is an excellent cutting pole for places where you don't have electrical service, and the battery does last for quite a good number of cuts. And keep a good eye on the level indicator for the oil, as it is key to keeping the chain sharp - I would say that it is not as fast as a gas-powered regular hand-held chain saw, but the power via battery is as good as my neighbor's gas powered pole saw and far easier to store, and has the same speed (ALMOST) as that gas noise-maker. This is so quiet I didn't need my noise-cancelling headphones I use with my regular gas powered 18" chain saw.I would buy this again, but I would also buy FOUR extra chains, not just one.

Picked up the standalone tool after getting the mower, blower, and edger from Costco. Assembly is easy. Following a quick stop to grab some chain oil (which this appears to go through relatively quickly), we were in business.I was able to trim the trees around my property as well as down some fig trees of considerable girth on a single battery rated for 4 amp hours.Machine cleans up easily after doing work. Adjustments on the chain tension are simple with the included tool.

I have an older Echo 58V system and my chainsaw attachment failed. I found that for about the price of the Echo pole saw attachment only, I could buy this whole Greenworks pole saw with charger, battery and tool. My Dad has one of their 80V 18" chainsaws and I was impressed with it, so I decided to grab this instead of spending the same for the Echo attachment for my 10 year old 58V trimmer that is unsupported by Echo.It seems lightweight and isn't quite as sturdy as the Echo setup, but it's also a fraction of the price. It reaches quite high with a 10' pole and it cuts quickly. It only came with a 2.0 AH battery which is small, but it seems to run long enough to do the kind of trimming a homeowner would do with a homeowner grade tool, so no problem.The only downside I've had, and I've had it with other brands as well, is that the chain sometimes jumps off. I adjust it carefully and try not to twist the saw while cutting, but inadvertently do sometimes when I'm holding a 10' pole over my head and controlling a saw blade 18' off the ground. It's a pain to get it all straightened out when that happens, but I'm learning what not to do to cause it and it seems to be working better. It happened on occasion with my Echo as well, usually if the blade gets stuck and you're trying to wrestle it loose. There is no clutch on electric units so if they get jammed there is no throttle while tugging option. These either go full blast or they kick the overload and you have to wait a second and try again.Aside from that minor issue of overload cutoff vs gas burn the clutch until it goes dilemma, it works very well for the price and seems to be holding up well enough after a fair amount of trimming, sometimes even oak logs.Safety tips:* Wear eye protection so you don't get sawdust and wood chips in your eyes, or wasps (don't ask!)* Be aware if you are cutting really high branches as you'll tend to find yourself directly under the limb you are cutting. Be prepared to move out of the way, and consider tying a rope around any heavier branches so they don't fall on you.*Be aware that you are holding a saw 10' up in the air so it can want to sway around against the resistance of the wood, the wind and just general maneuvering. Make sure it does not hit any power lines or get stuck in a branch as it starts to sag. You may find yourself with a stuck saw and an unsteady tree limb that you have to climb up to separate. Falling limbs hitting ladders can be harmful, so try not to let it get stuck overhead.* Battery tips: To extend battery life, do not try to keep restarting the saw if the low battery cutoff occurs. It may be tempting to click it a few more times to finish cutting that last branch, but you may hurt the battery in doing so.* Let the battery cool off for a while before putting it back on the charger. The charger won't charge it until it cools to a safe temperature, however, the upper end of "safe" can still wear the battery out faster if you charge it while a bit too warm internally. A bonus is that if you're old like me you can also rest and cool off while waiting for the battery to cool off.* Once the battery is charged, remove it from the charger and don't top it off until you use the tool. Most chargers will monitor the battery and top it off when it goes down a few percent, but that adds wear and tear to it even when not being used, so it's better to leave it alone until you actually run it down a bit.My 58V Echo power head is still running on the original 10 year old battery and those were not all that well designed to begin with, so I attribute the long life to following these steps as much as possible (but not always perfectly). Battery tech has improved a lot since then as well, so this should last quite a long time with a little care. Happy "whackin" (take that as you will:-).
