Oregon CS300-A6 40V Cordless Chainsaw Review


In Brief: Oregon CS300-A6 Chainsaw Review

The Oregon CS300 is a cordless chainsaw sporting a 16-inch low-kickback cutting chain. Sporting a powerful brushless motor, the CS300 uses less battery power while maintaining optimal cutting performance. Cutting at 46 feet per second, this cordless saw saws through 12-inch logs in less time and with cleaner results.

More 50 years ago, Oregon’s low-kickback cutting chains put them on the map, but its innovations in chainsaw technology set it apart.

Today, we’re looking at the CS300-A6. This 16-inch brushless chainsaw provides higher cutting power and performance in a lightweight, compact design.

If you’re looking for a hassle-free chainsaw, checking out the CS300 should be at the top of your priority list.

Key Specifications of Oregon CS300

Oregon Cordless 16-inch Self-Sharpening Chainsaw with 4.0 Ah Battery and Charger

The CS300 is a cordless chainsaw that sports a sizable four-amp battery that delivers up to 400 cuts on a single charge through two or three-inch logs and branches.

Equipped with a 16-inch bar and chain, the CS300 has a maximum cutting depth of more than a foot, allowing it to fell thick trees in fewer swipes.

Maintaining cutting speed isn’t an issue either, thanks to its brushless motor and high sawing efficiency per charge.

More impressive is the CS300’s self-sufficiency.

The tool automatically drips lubricant onto the chain to maintain optimal cutting speed and performance, it self-primes and reduces cold-engine sputtering upon ignition, and it can sharpen the cutting chain on its own.

Unique Features

Let’s take a look at what exclusive features are in the CS300.

Brushless Motor

First of all, the CS300 is sporting a brushless motor. Compared to brushed motors, brushless systems dissipate heat more quickly; last longer by several years on average; and exert more torque for swifter, reliable cuts.

By Oregon’s estimates, the CS300’s brushless motor produces 40% more power than its brushed predecessors.

PowerSharp Self-Sharpening System

Sharpening a chainsaw’s cutting chain isn’t a scary process to most, but it is time-consuming. However, thanks to Oregon’s PowerSharp system, you can keep the tool sharp and ready for action in less time.

Here’s the kicker: you’ll need to purchase a PowerSharp chain (sold separately).

An external tool mounts directly onto the curved end of the bar (the kickback zone). By pulling and holding the trigger for three minutes, the cutting chain will be as good as new.

In the end, you’ll spend less time sharpening your tool and more time sawing.


Performance, Design, and Safety

Let’s take a closer look at the CS300’s performance, design, and safety features.


The CS300 is one of the best-performing cordless chainsaws. The brushless motor produces several hundred more cuts per charge than most of its competition.

Sawing through 12-plus-inch logs is something hardcore lumberjacks and lumber mills need to do regularly.

With the CS300, you can fell dozens of trees, prep hundreds of firewood-sized logs, or shape hundreds of square feet of shrubs on a single battery.


Based on customer reports, the CS300’s design is perfect in almost every way. It’s pretty disappointing that you need to purchase a separate chain to make use of the PowerSharp system, but you should considering get it anyway.

The CS300’s 12.9-pound build (fully assembled) requires hardly any muscle to lift and operate. According to past buyers, a single, fully charged battery pack supplies up to 45 minutes of continuous cutting power.


To start the CS300, you need to press and hold a safety lock button while pulling the trigger. This setup prevents accidental startups when carrying the tool with a single hand.

Bumper spikes found near the tool’s main housing allow for safer cuts through thick logs. They keep the chainsaw stable by keeping logs from pinching the bar, which could result in kickback.


Ease of Maintenance, Repairs & Warranty

We’ll give you a quick summary of what the operator’s manual says about maintenance and warranty coverage.

Ease of Maintenance and Repairs

As we mentioned in an earlier section, the CS300 is a self-sharpening tool, so that’s one less thing to worry about.

As for chain tightness, operators can turn the tool-free tensioning dial on the righthand side of the CS300 to tension the chain and remove any slack.

Also, a built-in self-lubricant feeding system ensures that the cutting chain is lubed up to prevent burn marks and accelerated wear and tear on the chain.

The only actual maintenance you need to do is adding lubricant to the oil tank and wiping the tool down before and after each use.


Oregon places a three-year limited warranty for the CS300 and two-year warranty on the battery pack. If used for retailing purposes, the warranty defaults to a two-year warranty for the tool and accessories.

Coverage includes the cost to diagnose, repair, and replace defective components due to manufacturing errors.

You can find more details on the warranty by contacting a customer service rep on their website www.oregonproducts.com, or by calling 1-800-223-5168.

Price of Oregon CS300

On the price spectrum, the Oregon CS300’s price tag is closer to the costlier end. Though brandishing the Oregon name, there are several brand-name cordless chainsaws out there that are less expensive with similar performance.

However, considering its beefy brushless motor, a higher upfront cost only makes sense. Ultimately, you’ll spend less on maintenance while also experiencing fewer problems throughout the CS300’s lifespan.


Who Should Buy Oregon CS300?

The CS300 is a chainsaw that everyone could use, from homeowners for trimming hedges to professional lumberjacks.

That said, tools with brushless motors are typically sought out by professional workers for their longevity and infrequent maintenance.

We see contract workers, lumber millers, and professional lawn services benefiting from this tool the most.

The CS300 pays for itself over time by reducing downtime (self-sharpening system, cold-motor ignition) and practically eliminating regular motor maintenance.

Why We Like It

The cordless, 16-inch CS300 chainsaw is an astounding product. It’s a fantastic all-around chainsaw that tackles all sorts of cutting jobs—small and large—without the slightest bit of trouble.

If productivity is a top priority, the CS300 should put all of your worries to rest.
