Hi guys, I have a Greenworks 20077 battery chainsaw which has worked great for a couple of years. However, today after working for a while when I re-start it it stops after about 20 seconds and the red warning light starts flashing and it beeps. I have checked the taughtness of the chain, the oil gauge is full, the battery is charged, the forward safety clip is in the right setting. I am very puzzled as to what is going on, I checked through the manual and it does not even mention the red warning light (top right of picture) or what might set it off.
Yes, the beeping alone can tell you that you are for eample low on oil, but I have never had the red light before. Grateful for some advice!

how old is it?
it could be a battery issue.
do you have other batteries to test on this
or will the batteries work in other gear you have?

It's a one year old product specific battery and the battery is working fine.

chainsaw which has worked great for a couple of years. A couple of years isn’t the same as 1 year old... Dutchy

ion batteries act this way when they do not like to charge.

This is why you dont buy battery operated tools like this. They demand way too much to do too little. I guess if you are doing little pruning cuts here or there maybe its sufficient but not for bucking. But those batteries are temperamental and go with little to no warning

Normally this is because the safety guard is pushed forward.
i have a different battery problem which I hope someone can help with. When I click the battery into the saw the green light comes on. It won’t go off by pressing the button and the saw won’t run. In fact nothing can be done except removing the battery but then replacing it the same thing happens. It’s all clean inside. Anyone had this problem?

load test the battery in a battery test jig.

With some brands, you can buy Bluetooth-enabled batteries. In this way, you can use an app to check the battery's temperature and voltage and update the firmware. I thought you could also reset a battery that won't charge, but I don't see that option in the Greenworks app.

There is mention of it in the PDF manual. It does not mention the warning light (?) but does say there is overload protection on the battery that shuts down the saw.....

"........This Lithium-ion battery pack is equipped with an internal circuit breaker which will automatically shut off the power to the tool and then reset itself once cooled. Follow these steps if an overload occurs while under heavy use: 1. Release the power switch and restart tool by depressing switch. 2. The battery may need to be removed for approximately 1 minute, allowed to cool and then reinstalled for use........"

This is only a 40V battery, but my experience with the 80V Pro batteries has been exemplary. I keep them indoors and in the chargers at all times, which maintain them at 80% or better charge. All remain fully functional:

Same issue on brand new greenworks chainsaw. It would run a few seconds then stop and beep. Nothing in the printed manual about this issue. This thread helped me some.
All I had to do was take out the battery, reseat it and it worked as expected.
Handy little saw. For smaller jobs. I just did some pruning on some pine trees. Branches 2 to 3 inches thick and it cut through them like butter. I'd seen others speak highly of this saw on other places on the internet so I gave it a shot. For less than 200 bucks for saw, 40v battery and charger it seems like a great deal.

I have a Greenworks Pro18 inch with a 4 ah battery, only a year old with not much use. I’ve had zero problems until..tried to start, chain brake was pulled back to start, battery was full, oil was full. Wouldn’t start just a clicking noise. Called Greenworks and they are sending a new saw. But..does anyone know how to fix this? I like my saw and if it doesn’t cost much I’d like to keep it. Any ideas?
