Regarding optimal use cases, you shouldn’t anticipate it to be capable of cutting large trees, as its power output has its limitations due to its battery-powered nature. Nevertheless, smaller tasks like cleanups, trimming, and pruning pose no challenge to this machine. Undoubtedly, the standout feature of this model is its portability.

No matter what power tool you’re looking at there always tends to be a rather large list of selling points. With that said it’s important you know which ones to zero in on and look for.

When it comes to cordless chainsaws, the big factor is all about the battery system that is used and the run time. The last thing you want to be dealing with is a battery powered chainsaw that runs out of battery halfway through your job. 

With this Cordless Chainsaw, you get a battery capacity of 40V MAX 2.0Ah. What this means is that you can expect to make about 60 4×4 pine lumber cuts before you need to charge the battery again. Not only that but the lithium ion battery can hold a charge for up to 18 months.

Recharging it to full capacity takes about 120 minutes with the charger. Given the considerable duration, it’s advisable to keep a spare battery on hand. This way, if your tasks require more power than a single battery can provide, you’ll be well-prepared for extended work sessions.

The chain brake comes into action rapidly, halting the chain’s movement almost immediately. It triggers upon contact with the handguard or activates automatically through an inertial system.

Chain adjustment requires no tools thanks to the hand-operated wheel-and-crank system. This mechanism enables the easy unlocking and locking of the chain bar, allowing you to adjust chain tension effortlessly and move the chain bar in and out, all without the need to loosen adjustment nuts or turn adjustment screws.

Maintenance poses a significant challenge; a series of tasks are necessary to ensure the seamless operation of your gas chainsaw. These include cleaning the air filter, renewing spark plugs, inspecting the fuel filter, fine-tuning the carburetor, and more. Certainly, a meticulously cared-for gas chainsaw could endure for over a decade. Yet, certain individuals lack the time or inclination for such endeavors. For them, the appeal of a cordless chainsaw, demanding only occasional attention, is far more enticing.

Other Features of the Black+Decker 40v Max Cordless Chainsaw

As big of a factor as battery and run time are, there are also other features that are worth noting with the BLACK+DECKER LCS1240 12-Inch Cordless Chainsaw. 

  • Fast smooth cuts are possible due to the 12″ Oregon low-kickback bar
  • Adjusting the chain is quick and easy, and doesn’t require any tools
  • Included are metal bucking spikes which enhance cutting stability
  • You can hold the unit in different orientations thanks to the handle that has a full wrap around
  • The chain remains consistently lubricated thanks to the automatic oiling system
  • Great addition is the impressive cutting speed
  • Facilitated by a robust electric motor, this tool achieves elevated rotational speeds, empowering homeowners to effortlessly cut through small trees, shrubs, and limbs
  • It weighs just over 10 lbs which means it’s comfortable to handle
  • The package includes a scabbard and guide bar which will ensure the blade stays protected when you’re done using it
  • The chainsaw is relatively easy to assemble out of the box
  • Because this unit is electric, you won’t have to worry about fumes and gas, which means it’s a much more environmentally friendly option
  • The unit offers a three-year limited warranty

For all its pros it does have a few cons as well that you’ll want to be aware of before making a decision. According to users, this one has a few potential cons, including:

  • The battery may need to be replaced sooner than anticipated
  • The replacement battery can start to get costly
  • Some complain that the run time isn’t as long as advertised
  • The limited oil capacity might be a concern. To address this, it’s recommended to have chain oil readily available, given the relatively small reservoir size. While not a significant drawback, it’s certainly a noteworthy aspect to consider.

Clearly, the biggest complaint with this unit tends to focus on the run time and overall battery lifespan, which are both worth taking note of. 

Thanks to a number of features, this particular model from BLACK+DECKER can actually make for a good entry-level model. 

If you’ve been thinking about purchasing a chainsaw but don’t want to get in too over your head, the fact that this one is fairly lightweight, comfortable to hold, and is doesn’t feature too many bells and whistles that you need to learn how to use, then it can be great if you’re looking for something user-friendly right from the get-go.
