Product Description

For high-powered, gas-free sawing, the BLACK+DECKER 12-Inch 40V MAX* Cordless Lithium-Ion Chainsaw is the lightweight, electric chainsaw to get the job done. Part of the 40V MAX* outdoor system, this chainsaw is made with a 12” OREGON low- kickback bar and chain for smooth, fast cuts. With a full charge, the battery can last for an average of 60 4x4’ lumber cuts. A built-in automatic oiling system makes lubricating the bar and chain simple, and the chain tension can be adjusted without tools. For increased safety, a front hand guard protects from debris and a lock-off button prevents accidental activation. The included guide bar scabbard protects the blade when not in use. This lightweight unit is even easier to maneuver thanks to wrap-around grip handles that allow for a variety of angles. For easy, untethered sawing, the 12” Cordless Lithium-Ion Chainsaw will be your go-to for years to come. *Maximum initial battery voltage (measured without a workload) is 40V. Nominal voltage is 36V.

Good chain saw withing its limits.
4 Stars
Good chain saw withing its limits.
One thing I have to say right off is that this will not replace a gas chain saw. For bigger jobs, only a gas chain saw has the power and fuel capacity to complete a full-size tree felling and cutting up.Having said that, this is an excellent saw for smaller jobs and I just love its ease of use. In my late 50s, I don't enjoy the fight to start a gas chain saw and this electric model is just fantastic! There's little vibration and little noise compared to a gas model. You slap the battery in and go! No fuss and no pulling the starter handle X times until start on a gas model. It's a joy to use.AS you can see from the pics, I had a standing tree of about 10" which was probably a little bigger than I should have used it on, but this was a test after all. The second pic shows the tree lying on the ground. As you can see from the third pic, there was some leakage of oil over time I never really noticed until I looked down at my pants! The next two pics show the number of drums I cut on one battery charge while the last shows the diameter of the cuts I was making.The battery life was actually good considering the thickness of the tree it had to saw through and I got the hardest part done. The battery is the real constraint and wish I had bought another, but they're like $50 a piece! If my first project had been a smaller tree, it probably would have finished it. But, frankly, I would have liked to have another battery.I got a late start in the day so, by the time the battery was charged, it was getting on in the evening and I didn't finish it. I'll finish tomorrow. How does it cut? Very well, but when it bogs down due to too much pressure by me, it just quits. You just have to back off a little, start it again, and go slower. I was disappointed by how much it cut just at the same time I was impressed by how much it cut. It clearly isn't a replacement for my 18" Stihl gas powered saw, but it sure reduces the number of occasions I'll have to reach for it on the wall of the garage!One thing I need to point out is that it does not have a chain brake. What looks like a chain brake is just a hand guard. You do have to push a button on top the handle before you can pull the throttle trigger as a safety feature. Also, it uses bar and chain oil rather quickly due to the small size of the reservoir and the small amount of leakage.Adjusting or tightening the chain is very easy. It's very easy to turn the retainer screw assembly and then turn the adjustment wheel to move the bar in and out to tighten and loosen the chain tension. Be sure to check that frequently just as you would a gas model. Always use eye protection, by the way!On the whole, I'm happy with this chain saw so far. If you have the money, get a second battery! It's a good choice for small jobs and as a companion to a gas model for a second person to cut branches off or clean up.

Reviewed in Canada on November 6, 2023
I bought this for my wife as she operates a farm and sometimes needs to make a fence post or cut an obstacle and she has a hard time starting my gas powered saw.
Out of the box it resembles a child's toy, which has me a bit nervous, but happy to say that it has impressive capabilities.
The battery lasts as long as the oil reservoir.
Overall happy with my purchase to this point.
