Buyer’s Guide

Before purchasing a chainsaw, here are a few factors to consider.

Fuel Source

The two most common types of chainsaws are electric and gas. Electric chainsaws are powered by a cord or a battery. They’re lighter and more affordable than gas chainsaws, but they aren’t as powerful, working best for smaller projects, such as trimming tree limbs. A battery-powered model also has to be recharged periodically, and one with a cord is limited to how far that cord reaches. Gas chainsaws, on the other hand, are more powerful than electric chainsaws and are capable of cutting thick logs. However, they’re heavier, more expensive, more difficult to start, and more harmful to the environment.


Electric chainsaws are usually measured in volts, while gas chainsaws are measured in cubic centimeters (cc). The higher the number for both, the more powerful the chainsaw. Common maximum voltages for electric chainsaws, which measure the initial jolt of power when you turn them on, are 20 and 40. For gas chainsaws, a common cc range is 31–110.

Bar Measurement

This measurement refers to the usable part of the bar, which is the part that sticks out of the chainsaw’s casing. The bar length is the chainsaw’s full length, which is a few inches longer than its measurement because the first few inches are within the casing. Common measurements are 12, 16, 18, and 20 inches. A longer bar allows you to cut through thicker wood, but it also makes the machine heavier and more cumbersome.

Chain Brake

A common safety feature on chainsaws is a chain brake. This feature stops the chain from moving if it encounters an abrupt impact. Because of the risk of injury from the chainsaw’s blade, you’ll want to ensure that your model has this feature.

Extra Features

There are a variety of features that will make using your chainsaw easier. For example, a chainsaw with an automatic oiling system oils the tool for you without you having to press a button, and a tool-less chain adjustment allows you to change the tension of the chain quickly and easily.

Frequently Asked Questions

Can you change a chainsaw blade?

Yes. You can change your chainsaw blade if it gets dull or if you want a different length. However, dull blades can be sharpened, and most chainsaws use a specific blade length that works best with their engine. Before moving forward with the change, read your user manual to see what the manufacturer recommends.

How do chainsaws start?

You can usually start electric chainsaws with the push of a button. With gas chainsaws, you have to pull a power cord repeatedly until the motor starts.

What is the catalytic converter in a gas chainsaw?

The catalytic converter is the part of the engine that filters the gas, preventing pollutants from entering the air. Catalytic converters are also common in other machinery with gas or diesel engines.
