Chainsaw, Single Product Review

Black and Decker, one of the most reliable home improvement brands have come up with a solution to clean stormed backyards with ease and convenience.

The LCS 1240 is a compact, portable, and lightweight cordless chainsaw that can make smooth and fast cuts without any hassle.

The good thing is that it runs on 40v battery power and the drainage is properly optimized so that you can finish all your pending tasks in a single go.

Ideal for occasional wood and tree cutting, the Black and Decker 40v chainsaw review also includes a tool-free chain system with durable construction.

Let’s break it down and see whether it can give tough time to the likes of Greenworks, Milwaukee, or Worx chainsaws.

Have a look:

What Makes Black and Decker 40v Chainsaw a Standout in 2024?

For starters, the tool does come with a powerful electric motor that yields improved cutting results.

I might as well praise the compactness of the chainsaw, which is similar to what I saw in models from Worx and Dewalt.

But, B+D is not about compactness only. It’s extremely lightweight and makes sure that you can carry on with routine cutting tasks without actually fatiguing yourself.

All these qualities included within the chainsaw makes it a standout among other brands and models, respectively.

Moving on, take a look at what I think about the chainsaw in relation to its power, efficiency, and handling interface.

Our Black and Decker 40V Chainsaw Review in 2024: First Impressions

black and decker 40v cordless chainsawThe tool already came preassembled, so I didn’t waste my time further and took it out of the box immediately.

First impressions: It felt extremely lighter without the battery and oil. Besides the overall construction was quite reliable and rugged enough. The chainsaw gave vibes like it would run for many years to come without any hassle.

I also received a 40v, 2.0Ah battery along with a standard B+D charger, so I plugged it in for proper charging.

Meanwhile, I checked out the bar and chain mechanics, which were solid enough. Not to forget, Black and Decker offer a sturdy Oregon bar with a spiky and sharp chain.

The oil window box is just at the top of the handle. I didn’t like its placement here as it was difficult for me to fill the window without any overflow.

I tucked in the battery, filled the chainsaw with standard bar and chain oil, and pushed the brake to start the tool.

So far, the chainsaw didn’t cause any problems. Hence, I took it out to make some random cuts, i.e. clearing a fallen 8” tree, which it did superbly.

Moreover, there was no noise and that’s what impressed me a lot while I was busy cutting shrubs and limbs.

Although the bar’s too small, I still tried it out on a 12” thick wood log, and it did penetrate without getting jammed. Quite frankly, the cordless chainsaw offered a powerful cutting interface that I did not expect from it.

Overall, the tool was solid enough. Black and Decker 40V chainsaw helped me cut some of the dead trees standing in my backyard. Plus, its battery optimization was well up to the mark.

In a nutshell, I’ll give it a solid 9.5/10 for doing the work that it’s not supposed to do without causing any kickback issue.

Technical Qualities Black and Decker 40v Chainsaw Offers in 2024

Nevertheless, some of the major technical qualities that this chainsaw offers go as under:

Electric Motor:

The powerful electric motor helps the tool rotate at a higher speed and allows homeowners to cut small trees, shrubs, and limbs without any hurdles.

More than that, it’s also responsible for producing low noise, thus ensuring a hassle-free woodcutting experience.

The motor also enhances the overall torque of the chain, allowing it to move quickly. Hence, it can penetrate deep inside thick wood logs.

Low-Kickback Bar and Chain

The 12” Oregon bar, on one hand, is quite durable and, on the other hand, it penetrates deep wood materials quite easily.

Plus, the mechanics of the bar allows it to move flawlessly without causing any kickback or getting stuck issues.

Talking of the chain, however, it’s spiky enough. Combined with the bar, it produces amazing results and slices thick wood logs with ease and convenience.

Automatic Oiling System:

Automatic oiler included within the chainsaw keeps the chain lubricated enough. It also keeps the chain away from getting any wear or tear.

Therefore, it’s easier for homeowners to keep cleaning their backyard by removing stubborn shrubs and limbs.

You can use any standard bar and chain oil to fill automatic oiler. Just make sure that the quality of oil is well up to the mark.

Tool-less Chain Tensioning System:

Adjusting the tightness of chain doesn’t get any better than this. Black and Decker 40v chainsaw offers a durable knob on the right side.

Just move it clockwise to tighten the chain in case it gets loosened after a wood cutting task.

Easy Handling:

Handling the tool is as easy as cutting butter with a sharp knife. It comes with a wrap-around handle so you’ll get the right angle to cut wood from different directions.

Besides, the compactness and use of lightweight materials already make the chainsaw an easy handling tool. You can carry it around for a long time and still not feel any burden on your hands or arms.

Variable Speed Trigger:

The speed trigger installed on the inside can control the cutting speed of the chainsaw.

Press it more if you are cutting a thick wood log. Similarly, keep it at a steady rate if you are busy slicing some medium sized firewood material.

Battery Timing:

Not to forget, Black and Decker 12” cordless chainsaw does come with a 2Ah battery that offers 40v power to the motor.

It offers around 60 cuts on a 6×6 limb that’s pretty cool considering that it uses 40v power.

Some of the positives and negatives this electric chainsaw offers are as follows:


  • Compact and lightweight chainsaw.
  • Cuts 8” to 12” wood logs easily.
  • Suitable for taking down dead standing trees.
  • Automatic oiling system keeps the chain lubricated.
