Black & Decker LCS1240 Cordless Chainsaw Review


In Brief: Black & Decker LCS1240 Chainsaw Review

The LCS1240 by Black & Decker is an easy-to-use chainsaw that runs on a 40V, 2-AH battery pack. As a battery-powered chainsaw, its cutting speed of 16.4-feet-per-second is quite limiting. Still, for smaller tasks such as prepping firewood and shaping shrubs, the LCS1240 is one of the most reliable tools on the market.

Being in the game for over a century, there’s little wonder why Black & Decker is one of the top power tools manufacturers on the planet.

In today’s review, we’re going to check out the LC1240 12-inch cordless chainsaw. As a battery-operated tool, it offers maximum portability without weighing your conscience down with toxic exhaust fumes.

Though the bar blade is only a foot long, there’s plenty of cutting jobs this tool can do.

Unique Features

Now, let’s spend some time going over a few of the LCS1240’s unique features.

Shareable 40V Max Battery Pack

The LCS1240 belongs to the 40V* Max family, meaning that its battery pack can power other tools in the family and vice versa.

If you’re planning on building up an arsenal of garden and workshop power tools, it’s always a good idea to choose a single, well-known brand. Why not Black & Decker?

Optional Additional Battery Pack

According to Black & Decker, a fully charged battery can produce up to 60 cuts through 4 x 4 pine lumber.

By customer estimates, you’ll get up to 30 minutes per charge.

If you’d like to increase your work time by 100%, then consider picking up the LCS1240 kit that includes a backup battery.


Performance, Design, and Safety

In this section, we’ll go over the LCS1240’s performance, design, and safety features.


The 16.4-foot-per-second cutting speed makes sawing through seasoned logs easy, let alone felling Douglas firs.

This chainsaw is best used for trimming hedges and cutting thin trunks and branches for easy removal. However, you certainly could use it to prep firewood or mill lumber.

As a cordless-electric model, it cuts a lot slower than gas chainsaws.

However, if you’re seriously considering picking this model up, then cutting speed and productivity are most likely not on the top of your priority list.


In terms of design, the LCS1240 looks like any typical 12-inch cordless chainsaw. It weighs only 8.3 pounds, making it categorically lightweight and easy to handle.

The amount of work time each fully charged battery provides makes this an excellent tool for light-duty cutting jobs.

Additionally, maintaining chain tightness without employing spanners, wrenches, or screwdrivers is a huge plus.

As long as the chain is adequately tightened, there’s enough lubricant in the tank, and you exercise the right precautions, this tool couldn’t be easier to use.


The LCS1240 comes with a low-kickback bar and chain produced by Oregon.

It’s pretty much standard in most entry-level and mid-range chainsaws.

Still, the stock blade and bar are a blessing for those who aren’t seasoned chainsaw veterans since it reduces the risk and severity of kickback.


Ease of Maintenance, Repairs & Warranty

In this section, we’ll go over common maintenance issues and quickly describe what sort of warranty Black & Decker provides.

Ease of Maintenance and Repairs

The most frequent issue that arises in chainsaws is a loosened chain. On the side of the LCS1240 is a dial that you turn to tighten the chain.

This system does not require removing the side plating with spanners or screwdrivers.

Also, as a cordless tool, you’ll want to make sure that the battery pack is never overcharged. On average, 40V battery packs have a lifespan of between two and three years.


Black & Decker provides a three-year limited warranty on the LCS1240.

The warranty covers the basics—costs for repair and replacing defective parts as a result of manufacturing faults, provided that the buyer did not modify the tool or mishandle it in any way.

Price of Black & Decker LCS1240

By 12-inch cordless chainsaw standards, the LCS1240 is a bit on the pricey side.

However, most comparable chainsaws—e.g., same bar length—either weigh more than the LCS1240, or their battery packs don’t come close to the LCS1240’s 40V Max.

If you’re looking for a high-quality cordless chainsaw at a reasonable price, this is for you.


Who Should Buy Black & Decker LCS1240?

The LCS1240’s 12-inch bar is a giveaway of who it benefits most.

This chainsaw is best suited for trimming hedges, pruning trees, and cutting branches into manageable pieces, but professionals will also appreciate the extreme cutting power that this cordless tool provides.

Also, as a cordless-electric tool, the LCS1240 will leave less of a carbon footprint as opposed to gas models.

Electric power tools are better for the environment, so start your search for environmentally friendly power tools by giving this Black & Decker chainsaw careful thought.

Why We Like It

The LCS1240 delivers astounding cutting performance and effortless maintenance.

It’s not a budget chainsaw, but your investment will pay you back in dividends in the form of productivity and easy maintenance.
