Key Specifications of Makita UC4051A

Makita-UC4051A Chain Saw, Electric, 16 in. Bar - Sliver

The UC4051A is rocking a beefy 14.5-amp motor that moves the cutting chain at a rate of 48.33 feet per second.

Although this may sound slow by electric chainsaw standards, the lack of speed is more than made up for by torque delivery, or how hard-hitting the chain’s links dig into your workpiece.

Electric chainsaws are typically used for light-duty sawing tasks such as limbing trees and trimming hedges.

Although the UC4051A excels at these jobs, it does much more than that. The 16-inch guide bar has a max cutting depth of 15 inches, allowing you to saw thick trees in a single sweep.

Unique Features

The only unique features worth mentioning in the UC4051A are as follows.

Tool-Free Tensioning System

Though not unique in a general sense, the UC4051A’s tool-free tensioning system is worth noticing. To tighten the chain around the bar’s edge, you first need to loosen the bar by turning the lock nuts counterclockwise.

While pulling the bar upward slightly, turn the tensioning dial until the bottom of the cutting chain is snug around the bar. Re-tighten the lock nuts, and you’re done!

Overload Protection

Electric motors have longer lifespans than gas models’ combustion engines, mainly due to overload protection features.

In the case of the UC4051A, its motor will automatically shut off when there’s too much resistance from the workpiece. This system preserves the motor and reduces the frequency of maintenance issues to nearly zero.


Performance, Design, and Safety

Now onto more pressing matters: the UC4051A’s performance, design, and safety.


In terms of performance, the UC4051A behaves similarly to a 32-cc gas-powered chainsaw. Now, that’s not extraordinarily powerful, but it’s enough to fell thick trees, let alone remove branches and trim shrubs.

The main benefit of choosing a corded-electric model over gas and cordless is its infinite runtime with zero emissions and lighter weight.

There’s also no fuss at all when it comes to ignition—simply press the safety lock button and start trigger together, and it’s ready to roll.


Design-wise, the UC4051A isn’t much different from other Makita electric chainsaws. It’s lightweight but doesn’t have the cheap feel many plastic-y chainsaws have.

It comes with cushiony grips on the front and back handles to improve comfort and aim. The UC4051A 16-inch bar can also cut up to 15 inches into tree trunks for efficient felling and dimensioning.


Other than the overload protection system, the UC4051A’s safety features are pretty standard.

There’s a chain brake that stops the cutting chain in its tracks in emergencies, an auto-oiling mechanism with adjustable feed rate to supply you with as much oil as you need, and metal bucking spikes for extra convenience when sawing at the maximum 15-inch depth.


Ease of Maintenance, Repairs & Warranty

Here, we’ll quickly describe how easy it is to maintain the UC4051A and what sort of coverage Makita provides.

Ease of Maintenance and Repairs

Taking care of your UC4051A is hassle-free. The auto-oiling and tool-free tensioning systems pretty much take care of the most frequently occurring problems (loosened chain and adequate lubrication).

As an electric chainsaw, the UC4051A’s 14.5-amp motor isn’t as prone to failure as combustion engines, thereby reducing the frequency and cost of repairs.

Buyers have used their UC4051As for several years without experiencing motor issues.


Makita provides a one-year limited warranty that covers the expenses of repairing and replacing defective parts.

Only 12 months of coverage may not seem like much, but knowing Makita and its high-quality products, you’ll most likely never need to make use of this warranty.

If you do, be sure to let the company know by reaching out to a customer service rep. The number to call for buyers across the US is 1-800-462-5482.


Price of Makita UC4051A

There’s no point in denying that the UC4051A costs a pretty penny. After seeing what this corded-electric chainsaw has to offer and what it can do, we’re not surprised at all.

Electric chainsaws don’t require fuel mix or experience maintenance issues as frequently as gas models, so you save money in the long run.

In short, the UC4051A is worth the investment.


Who Should Buy Makita UC4051A?

Judging from the bar’s size, the Makita UC4051A would appear to be exclusively marketed to homeowners. However, its 14.5-amp motor and astounding cutting speed and torque tell an entirely different story.

Professional loggers will find value in this tool, provided they have a portable generator to take with them to the woods.

Wood craftsmen will also appreciate the UC4051A for its ability to slice thick logs into smaller workpieces for milling.

As for the homeowner or occasional user, there are more affordable electric chainsaws out there with more appropriate specs for light-duty trimming and limbing.

Why We Like It

The UC4051A is a residential-grade chainsaw that can also be used for commercial purposes.

The 16-inch bar powered by the 14.5-amp motor saws at a max rate of 48.33 feet per second, making clean and effortless cuts through logs up to 15 inches in thickness.

Combined with close to zero maintenance problems, the UC4051A is a worthy investment for infrequent and hardcore users alike.
