Key Specifications of Greenworks 20332

No products found.

The 20332 is a corded-electric chainsaw that draws power from wall outlets or generators. Corded models such as this one aren’t particularly known for their portability.

Still, in terms of power output, the 20332 outshines most cordless models by a wide margin.

With an 18-inch-long bar and cutting chain, the 20332 can saw through thick logs and fell trees of up to 17 inches wide in a single cut.

However, without a portable generator, the 20332 will most likely limit your work to sawing logs for firewood and trimming hedges.

This video will show you what to expect out of your brand-new 20332 chainsaw:

Unique Features

Let’s see what unique features are in the Greenworks 20332.

Tool-Free Tensioning System

You’ll find tool-free tensioning systems in almost every modern corded-electric chainsaw model, and the 20332 is no different.

This system allows operators to tighten the chain without the use of screwdrivers or spanners.

On the side of the tool, there’s a large dial that, when turned clockwise, will tighten the cutting chain around the length of the bar’s edge.

Users should check the chain’s tension and tighten it before pulling the trigger.

Wrap-Around Handle

The shape and design of the handguard play a role in how much debris it blocks. The wrap-around style of the front handle keeps twigs and foliage hitting your hand.

Not only is the handle grippy, but your grip around the tool will not be compromised by flying pieces of debris.


Performance, Design, and Safety

Here, we’ll describe how the 20332 performs, how well it’s built, and what safety features are in place.


The advantages of such a large motor become apparent as soon as you activate the motor. The cutting chain spins at a rate of up to 8,000 RPM to cut through soft and hardwood logs cleanly in two.

The 18-inch bar plays a pivotal role in felling wide trees.

A single cut with the 20332 will send trees of up to 17 inches wide careening downward, and the long chain will make quick and easy work out of turning rough logs into firewood.


The 20332’s design isn’t much different from other Greenworks chainsaws. It’s made almost entirely out of a plastic composite that, though durable, is prone to cracking if not stored properly.

The 18-inch bar is a huge benefit for those that need to fell thick trees. However, the cutting chain will need constant tensioning to ensure that it doesn’t pop off of the bar blade.

A majority of customers haven’t experienced this issue, but enough have that it’s worth warning future buyers. A simple fix is to swap out the stock low-kickback chain with a standard one.


Apart from the chain releasing from the bar, the 20332 is safe to use. It doesn’t feature a chain brake, and the cutting chain will continue spinning even after releasing the trigger.

However, in a reasonable person’s hands, the 20332 is an entirely safe chainsaw for light- and medium-duty cutting jobs.


Ease of Maintenance, Repairs & Warranty

Taking care of a chainsaw is paramount to performance and longevity. We’ll quickly go over the maintenance issues with the 20332 and its four-year limited warranty.

Ease of Maintenance and Repairs

Electric chainsaws generally require less maintenance than gas-guzzling models. By customer reports, you can expect the 20332’s motor to last for more than five years before experiencing its first sign of trouble.

All that’s left to do is ensure that the cutting chain is taut around the edge of the bar and that there’s enough lubricant in the tank to keep the chain adequately slick.

Once again, if you get this chainsaw, consider swapping out the stock chain with a standard one.


The 20332 is protected by a four-year limited warranty that covers the costs of repairs and replacing defective parts due to manufacturing problems.

Assuming you’ve never tampered with the tool or replaced any components with non-brand parts, the warranty should remain valid for the entire four-year duration.

Price of Greenworks 20332

For its price, there’s very little reason for homeowners, DIY-ers, and even professional loggers would not want a piece of this machine. You’re getting powerful, deep-cutting performance in a compact model.

Just make sure to use the savings to pick up the right outdoor-safe extension cord to increase your range of movement.


Who Should Buy Greenworks 20332?

Corded-electric models are generally used by homeowners and DIY-ers for simple cutting and trimming tasks. The 20332’s cutting performance—though elite—is not at the same level as gas-powered models.

Considering that the 20332 comes with a long 18-inch bar and a powerful 14.5-amp motor, professionals would also benefit from this tool.

Just make sure to have a portable generator on hand if you plan on felling trees deep in the forest.

Why We Like It

The 20332 is an exceptional corded-electric chainsaw. The 18-inch bar and chain make slicing through thick tree trunks a breeze.

It’s unfortunate that there aren’t very many safety features and that the stock chain can pop off of the bar constantly. Still, overall, it’s an excellent tool for many cutting jobs.
