Great choice if you don’t like fooling with pull-start gas chainsaws. Excellent vibration reduction and a surprising amount of power for as light as it feels.

Some tips to consider

I have encountered a lot of people who believe there is only one type of chainsaw worth having is a pull cord style gas unit. I am not surprised since not so long ago I also felt the same.

There are different types of chainsaws, but the focus here is on the electric chainsaw. You can use a chainsaw in limbing, pruning, and chopping tree trunks into smaller bits to use as firewood.

GreenWorks 20322 Chainsaw

Should you desire efficiency, maneuverability, and pace when cutting or pruning, a battery powered chainsaw might be a good choice. However, before you contemplate getting a chainsaw, you should be aware of the safety implications of using a chainsaw. The maintenance culture associated with a chainsaw requires consistency on your part.

Also, the maneuverability of a chainsaw might be a challenge, so if any of these factors tick attributes of your ‘do not buy tools’ then perhaps you might want to consider alternative cutting tools.

The GreenWorks 20322 G-MAX 40V 16-Inch Cordless Chainsaw

  • Compact and simple design – This is strange in a chainsaw but yet quite helpful. It is simple, lightweight and convenient.

  • Tool-less chain tensioning – With this feature you wouldn’t require any tools to adjust the tension in the chain.

  • Limited use – This chainsaw cannot be used to cut down big trees or any other task which demand enormous power.

Features and benefits

The 20322 G-MAX offers you a cordless chainsaw which is versatile for all your light cutting and trimming tasks. It has an assortment of features such as the instant electric start, able to run up to two hours with a 4AH battery, and lighter than most chainsaws.

Adjustable Tensioning System

This chainsaw has an easily adjustable tensioning system which is commendable since you wouldn’t need to engage in the use of tools to improve the tension of the chain. To adjust the tension, you turn the tension adjustment screw either in a clockwise direction or anticlockwise direction for an increase or decrease in chain tension. However, you will need to guide against an excess tension in the chains, since this decreases the efficiency of the chainsaw.

Automated Oil Primer

Lubricating the chains and bar is very important since the lifespan of the chainsaw depends on how diligently this is carried out. When a chainsaw comes with an automated oil primer, you are only required to fill the oil compartment while the chainsaw handles the oiling.

Lock off Switch

Accidents happen so eliminating the possibility of such happening would be great. This chainsaw has a switch which enables you to lock the ignition switch, so the possibility of turning on the switch in error is history. This minimizes the possibility of you getting injured.

16 Inches Bar and Chain

The bar and chain determine to a great extent its versatility and efficiency, so it’s great that this chainsaw makes use of a high-quality bar and chain, renowned for its quality and performance.

By measuring about 16 inches in length, you can use this chainsaw for multiple ranges of cuts swiftly and with precision. Everyone knows one of the biggest causes of injuries with the use of a chainsaw is the kickback effect. This occurs when there is unexpected contact between the area around the chain and the wood which is being cut. The bar and chain used in this chainsaw have been designed to reduce kickbacks. However, you still need to take caution when using the chainsaw.

Battery Powered

This chainsaw runs on a 40V battery with a capacity of 2.0AH; this is a great feature since all you need to do is get the chainsaw charged and you are good to go without the need to carry a cord around. Another great feature is that the battery can be easily detached. This allows you get a spare if there is a need for more power than what a single battery can provide.


GreenWorks 20322 G-MAX isn’t the only cordless chainsaw available. Here are some alternative chainsaws similar to the LCS1020 but with variations.

Green Works 20312 G-MAX Cordless Chainsaw

This chainsaw is produced by the Green Works group and like the LCS1020 it is battery powered. However, it has an 18-inch bar which makes for a wider range of cuts. With a 40V and 4AH battery calibration, you can use the chainsaw longer than the LCS1020. The price of this chainsaw is rather costly about $200 more compared to the LCS1020. It is suitable for any individual who desires more power, a better battery and is willing to spend a little more.

Green Works Pro GCS80420 Cordless Chainsaw

Also produced by Green Works, this chainsaw runs on an 80V, 2Ah Battery which is bigger than that of the LCS1020. It has an 18-inch Bar and chain which allows you make cuts not feasible with the LCS1020. With a brushless motor, you get more power and less vibration a feature that a lot of models lack. So if you want more power, a battery which last longer then perhaps this chainsaw might be worthy of consideration.
