Good chainsaw.
Chainsaw works as expected. When not in use it leaks oil but the Instructions say it will leak oil. Guess I'll have to empty oil between uses.

Works great. Battery run time is not an issue.
Works great overall. Blade teeth jammed on live lumber over 15" thick logs but no problems with any thing less.

GreenWorks Pro 18 inch chainsaw
The first day I got my chainsaw I cut four 6" diameter fence posts and eight 2" diameter fence tighteners out of old hedge trees and only reduced the battery capacity by one third. So much more convenient than messing with gas, oil and hard starting; just grab and go and cut.

Great saw with one issue chain oil leaks out the bottom
I just bought this saw about a month ago and used it for the first time 2 weeks ago. The saw performs great. It cut through everything I tried to. The only issue is the chain oil leaks out of the bottom of the saw and leaves puddles of oil where ever it stays. Other than this issue the saw is great. I would also recommend a second battery if you are going to be using the saw for a while so you can charge one while using the other one.

Power and Performance
A chainsaw is something I need occasionally, but not too often. Usually, the need comes from a storm that knocks down a tree limb or, under rare circumstances, an entire tree. At a family property on the Eastern Shore of Maryland, one of those storms brought down part of a tree. I had owned a gas-powered chain saw but gave it to a neighbor when my family relocated, so I decided to purchase this cordless chainsaw.

My daughters and I packed up the chainsaw and the 80 volt battery from our Greenworks snow thrower, departed for the family property, and put the chainsaw to the test this past weekend. The performance was truly impressive, with plenty of power available. The 2 amp-hour 80 Volt battery lasted almost a half hour, which may be an issue for extended use, but only requires about that long to recharge. Taking a break while the battery recharged worked nicely for us.

Long ago, my grandfather taught me "let the tool do the work" and I was giving the same advice to my daughters as they cut some of the smaller diameter branches. Before long, we completed the final cut, and they were amazed by the chainsaw's power combined with the ease of use. And I was pleased to have made a great purchase decision.

How much for battery/charger for 18 in chainsaw? Does a chain come with the "basic tool"?
Destroyer of Gas Engines on Apr 22, 2016
BEST ANSWER: Please use the link provided below to view both the battery and charger.

The chain is included with this saw.
I own a Kobalt 80vt blower. Will my 80 vt battery work in this green works 18" chainsaw?
Richard C on Feb 19, 2017
BEST ANSWER: No, the 2 brands are not compatible.
Does it matter whether you purchase the 2Ah or 4 Ah battery for this chainsaw?
A shopper on Jul 5, 2017
BEST ANSWER: Depends on duration of usage. Volts = power; Amp hours = runtime. 4 Ah will have approximately twice the runtime so depends how long you need to utilize the saw between charges.
Where do I get the battery & charger?
Jerry on Apr 22, 2016
If you wanted this saw and you don't already have another tool with the right battery and charger then I would recommend buying a complete tool package as it is more cost effective.
The reconditioned battery alone is $120.,default,pd.html?start=56&cgid=greenworks&srule=price-high-to-low
The charger is another $80,default,pd.html?start=77&cgid=greenworks&srule=price-high-to-low
The complete package isn't currently available on CPO Outlet but is available on Amazon for $300
I bought the bare tool as I already had the snow thrower and the string trimmer as complete tool packages so I had 2 batteries and 2 chargers already. I actually bought the string trimmer as a package in part to get a second battery as the trimmer and snow blower wouldn't likely be used in the same day anyway.
Does it have a pull cord?
A shopper on Nov 27, 2016
BEST ANSWER: No....this requires a battery that is started by a switch.
What is involved in "servicing" this chainsaw....just chain sharpening or chain replacement as needed? Easy to do?
Hillbonnie (vs. Hillbilly) on May 16, 2016
BEST ANSWER: Yes, since this is a cordless unit. The only replaceable part would be the chainsaw blade, which only requires adjustment at the chain tensioner
will the gba80250 battery work?
eric w on Nov 9, 2018
BEST ANSWER: Your question will be best answered by the manufacturer, who can provide you with the technical information. The number to reach the technician is 1-888-909-6757.
Does the battery from your 80 v string trimmer fit this chainsaw?
Karen S on Sep 7, 2017
BEST ANSWER: Yes, the 80V battery will fir both tools
