Can the battery stay on the charger after it is fully charged, or will it overheat / overcharge?

Asked by: Db186
Hello Db186, Thank you for your question. The battery chargers do have auto cut offs to prevent it from over charging. However, we do advise customers to remove the battery from the charger after it has been fully charged and to also unplug the charger from the outlet, as this is good electrical safety practice to do so. This will also help to prevent false defects reading and allows the charger to reset itself each time it’s used to charge a battery.

I have a G-Max 40V Green works cordless chain saw. The chain has come loose. How do I get it back on?

Asked by: Margy in Kansas
Hello Margy in Kansas, The chain is correctly tensioned when there is no sag on the underside of the guide bar and when the chain is snug but can be turned by hand without binding. New chains tend to stretch. We recommend checking the chain tension frequently and tension as required and when placing the bar on the bar studs, ensure that the adjusting pin is in the chain tension pin hole. You can find more information about the replacing the bar guide and chain here: https://www.youtube.com/watch?v=al2SoV1QqnI&index=86&list=PLlLcNiMNCMn_Qgcl7B3d1ly97pzCRZvjj. Should you still require further assistance, we would be interested in hearing more about this issue. Please submit an email using the customer contact page on our website or give us a call at 1-888-909-6757 (1-888-90WORKS).

can i use a 12” greenworks bar on this chainsaw?

Asked by: jojolex
Hello jojolex, Thank you for your question. We do not advise changing the original length of the bar/chain as this will affect the performance of the unit.
Answered by: GreenWorks Support

the first question on this page implies the 4.0ah battery should not be used with this chainsaw, but they are sold together? when using 2ah or 4ah 40v batteries, is the difference the time the battery will last but either is ok to use with this chainsaw?

Asked by: jojolex
Hello joolex, This questions was asked on a "Tool Only" unit. The 4Ah is more suited for the lawn mower and snow thrower, the 2Ah for the blower and chainsaw. But are interchangeable. For every brand, the battery pack is designed specifically only for its products. These cordless tools have their very own technology and features and by that, each of these features requires a certain amount of voltage to deliver the optimized performance. The higher the ampere-hour (AH) rating is on the battery, the longer the run time will be in comparison to a lower ampere-hour battery.

I recently bought a Greenworks mower that uses the BAF724 40V Lithium 4.0 AH battery. The battery and charger came with the mower. Will that battery work with this chainsaw?

Asked by: KBA1
The optimal weight distribution requires the use of either our 2.0Ah or 2.5Ah batteries. This process also reduces the chance of kickback when saw in in use.

Rated 5 out of 5 by from Exceptional run time I have had this chain saw for about 3 years with most of my use of it in the Spring, Summer and Fall. I am always amazed at the long run time I get from the saw. I am often able to buck much more of a tree than I predict. I find it easy to sharpen the chain and find any needed replacement parts online. It is comparable in weight to my old gas powered saw. The self oilier for the chain is great, but do take the time to clean out the housing over the chain from time to time to remove oil caked saw dust. If possible, used up all of the oil in the self oilier before storing it to prevent oil from leaking out when not in use.

Rated 5 out of 5 by from Cordless Chainsaw We have bought two....We have used the one for several years without a minutes complaint. The battery life is longer than mine some times... An easy to use tool for some many trimming, cutting....anything. It is a very safe saw with very little chance of kickback.. Keep the chain sharp and it will perform so excellent. I recommended a GreenWorks saw and my 81 year old sister has one that she can "hardly" live without. I have two gas saws one Husky 2100 xp and a Husky Rancher..and have cut thousands of cords of wood... But for ease and handiness this is the best. We have been sextons at a 15 acre cemetery for 30 years and this Greenworks tool is always nearby.

Rated 5 out of 5 by from Excellent saw I purchased three of these G-Max 40V saws several years ago to thin and prune juniper and pine on grazing land. Was not sure if the battery saws would hold up to the demands of ranch work, but hold up they did and without even one major problem with any of the saws over hundreds of hours of use. When I first got these saws one old boy I had working for me scoffed at it, but now these are the go to saw for any job within it's capacity. All but the large gas saws are collecting a lot of dust these days. Because of their light weight and ease of use, these saws became invaluable in steep canyons and rocky terrain. Three batteries per saw, a jug of oil and a file would keep my crew of three workers going all day.

Rated 5 out of 5 by from Works amazingly well! I have used my chainsaw on many different occasions, owning it for about a year now. It has never failed to impress me. The battery life is so much longer than you would expect. Only once or twice have I managed to outlast the charge. :) I've cut up downed trees following a tornador and done general limb/branch cleanup around my property. It exceeds my expectations every time I use it. It is easy to use and any needed maintenance is simple. I love that I can share the batteries among the Greenworks pole saw, trimmer and hedge clipper that I also purchased. What a great product!

Rated 5 out of 5 by from My second Greenworks saw I bought this saw to have a lighter saw for use at home. I have a Greenworks 80V saw for farm use some distance away. Both saws are well worth the money. I don't use chainsaws enough to be comfortable with them. An electric saw is simpler to operate and seems to me to be safer--less noise, no smoke, and you don't start the saw until you have it in position to make the cut. The batteries have all the capacity that I need and more. If you plan on doing extended saw work you may want a second battery.

Rated 1 out of 5 by from Only in cold climates I've had this for about ten months and was impressed with it in the winter weather, but once temperatures got above 70 it is too prone to overheating. Past 85 and I'd consider the saw near useless as you can only make a couple cuts a day before overheating. Perhaps this is because I'm cutting larger logs than most, some 14", but it's a 16" bar and overheating after four cuts, and not cooling down enough to use again until the next day is just unacceptable in my book. That's with multiple batteries and letting it rest in the shade for two hours, it can't run more than a few seconds before overheating again.

Rated 5 out of 5 by from It has passed the test of time I purchased this chainsaw several years ago ( when it was first available ). I use it all around our 35 acre property for trimming, pruning, removal of dead falls and even some firewood cutting. I was skeptical at first of a cordless saw but have become a true believer. It is lightweight, has excellent power and the battery is more than adequate for my needs. All in all the saw has surpassed my expectations and over the past several years has held up well, is durable and has passed the test of time.

Rated 5 out of 5 by from My first chain saw Received this saw as an early gift after wanting one for years. It was very easy to learn on. If you're like me and this is your first saw purchase, read the manual, wear safety gear, and it'll be good to you. I seem to wear out before the batteries do, so far. If you've read other reviews, you'll recall that the bar and chain oil does leak a little, so keep it stored appropriately to avoid staining your floor. (Only complaint is that I thought it was to include a carrying case. Mine did not, so I've been using a garbage bag instead.)
