First and foremost, the Black and Decker LCS1240 40V MAX Lithium-Ion Chainsaw is not designed for a heavy workload, but it is considered one of the best on the market for it's intended purpose.

It is aimed towards homeowners who have an occasional need to clear small trees, cut lumber, or chop firewood, and this model handles these smaller applications with ease.

The biggest advantage that this particular model has to offer is portability. It weighs a mere 10.4 pounds and can be carried around your property as needed.

On a full charge, the manufacturer specifications state that this chainsaw can provide 60 cuts on 4x4 pressure treated pine. The battery runtime is advertised as lasting between 30 and 60 minutes, but most reviewers agree that it tends to last only 30 minutes. The minimum amount of time needed to charge the battery is 120 minutes. While this might seem like quite the limitation, consumers always have the option to purchase additional batteries, so a backup is always available.

The wraparound design of the handle has won favorable reviews from users. The design makes it simple to use in a variety of positions – even the occasional awkward one. The handles are wrapped in a comfortable, forgiving rubber coating. This coating significantly reduces the amount of vibration the user feels when the chainsaw is running.

Another highlight of the Black and Decker LCS1240 is its automatic oiling system. While this might not seem like something of note, experienced chainsaw users know the hassle and annoyance that is having to manually oil a chainsaw. An integrated filter prevents any large debris from falling into the oil reservoir. It is worth noting that the reservoir cap does not have an included strap to keep it attached to the chainsaw, so users must be careful not misplace the cap.

In terms of design, the Oregon chain and bar measure 12 inches in length and are designed to minimize kickback and vibrations. This model’s design does not include a blade brake; however, there is a front hand plastic guard. Since this chainsaw is designed only for occasional use, it shouldn’t present an issue. The bucking spikes of this chainsaw are made from plastic. Users should be aware of this because it will be difficult to gain any leverage if you are attempting to use the chainsaw to cut larger logs.

The chain tensioning system is a two-step process. The black locking knob must first be loosened, and then the orange tensioning knob can then be adjusted to ensure proper chain tension. Because this model’s chain tends to stretch and expand once it heats up, some slack will be needed.

Black and Decker’s warranty for the LCS1240 is limited and lasts for only 12 months.

Longevity and portability are the two biggest selling points of the Black and Decker LCS1240 40V MAX Lithium-Ion Chainsaw. There are no gas refills or extension cords to contend with. Simply put, if convenience is what you are looking for, you can’t go wrong with this model. This price is also exceptionally affordable for most homeowners. Even though the price point is low, buyers shouldn’t automatically assume that it is cheaply made.

Conversely, this particular model does offer limitations regarding battery capacity and power, but for an “around the house” chainsaw, it will more than adequately do the job.
