An In-depth Review Of Jonsered Chainsaws – A Tradition Of Excellence

Jonsered chainsaws may not be a brand that you are familiar with, so you may be surprised at what these chainsaws have to offer. Made in Sweden, Jonsered is owned by the Husqvarna Group, a well-known name in the outdoor power tools industry.

Jonsered earned recognition by producing the first lightweight, single-man operation chainsaw in 1954. That is a long history for any brand. Additionally, Jonsered is continuing to work toward cleaner and more efficient engines and air filters. Reducing emissions is not only good for the environment, but it helps the chainsaw to run better as well.

The Top Choice

When you set the following chainsaws side by side, the clear winner is the Jonsered CS2245 18-inch 45cc 2-Cycle Gas Chainsaw. What it lacks in power, it makes up for in portability and function.

The 45cc 2-cycle Clean Power engine runs efficiently, and the Anti-Vib technology paired with the slightly smaller engine means even less stress and fatigue with repeated use. The added functionality of the quick-release cylinder cover provides easy access for maintenance and fueling.

The CS2245 is powerful enough to get through the toughest tasks. However, thanks to the balanced design and increased safety features, this chainsaw is easy enough to operate that even a first-time user will have success.

Buying Guide

Jonsered chainsaws are not made with a bunch of unnecessary features. The features that you find in these saws are the ones that are determined to make a true difference. Here are some of those features that Jonsered deems important enough to include in ALL their chainsaws.

  • A Turbo air cleaning system that gets rid of all but about 3% of the sawdust produced by the saw. This means that your air filter is less likely to get clogged and last a lot longer
  • Anti-Vib vibration-dampening technology that helps reduce the vibration that travels to your hands and arms while operating the chainsaw
  • Inertia-activated chain brake that is automatically activated when kickback occurs, or the saw is moved suddenly
  • Heated handles mean you can use your chainsaw in even the coldest of climates
  • Patented Peak Pulse technology, a way to increase the chain speed for faster work
  • A spin start, to reduce starter cord resistance by as much as 40%
  • Decreased emissions to improve fuel efficiency
  • A tool-less chain tensioner
  • A quick-release cylinder cover for quick fuel-ups and easy lubrication
  • Weight balanced for easy operation; the heaviest Jonsered chainsaw weighs no more than about 13 pounds


The bar length of a Jonsered chainsaw ranges from 14 to 20 inches, so you are sure to find the right bar size. Engine sizes from 38-50cc on gas models and cordless chainsaws with 58-volt batteries offer a wide range of power.


Commonly Asked Questions

Here are a few common things to consider when you are thinking of buying a chainsaw. The first is how you plan to use it.

Do you need a super-powered chainsaw for everyday use, or are you looking for a chainsaw to cut firewood for your backyard fire pit or fireplace? These questions are important when deciding which chainsaw will fit your individual needs.

In addition, there are a few other common questions that you may have when deciding which model of chainsaw is right for you.


How safe is the chainsaw?

Every chainsaw from Jonsered features some of the highest standards in chainsaw safety.

  • The chain brake is designed to stop the chain from turning in a fraction of a second to prevent serious injury due to kickback or sudden change of motion in the saw, such as a loss of grip or a fall.
  • The chain catcher protects the operator if the chain happens to break by preventing the chain from flying backward and hitting them.
  • A right-hand guard protects your fingers during operation or if a chain were to break.
  • The throttle lock prevents accidental operation of the throttle. You must engage the throttle lock to operate the throttle.
  • An emergency stop button allows you to stop the engine immediately.


What size saw should I buy?

The bar size and engine size that is necessary will greatly depend on the work that will be done with your chainsaw. For jobs that are small like trimming smaller limbs, brush, or shrubs, a 14- or 16-inch bar and a smaller engine will be more than enough to complete the job.

But for larger jobs such as cutting down entire trees, removing large limbs, or cutting green hardwoods will require higher powered engines like the 45-50cc models. These come with either the 18- or 20-inch blade and need those larger blades to accommodate the increased power.


How do you maintain a Jonsered chainsaw?

Jonsered has made maintaining their chainsaws as easy as possible. Their quick-release cylinder cover means never having to break out the tools to fill the oil and gas or to check the filter and spark plug.

Take the time to fill both the gas and lubricating oil before each use, as this will ensure proper lubrication through the entire tank. Ensure that you are only using the proper fuel mixer for the saw.

Some owners refuel their saws before they store them. Only do this if your saw is properly ventilated during storage. Gas fumes can accumulate in enclosed or improperly ventilated areas leading to increased danger.

Clean the air filter by rinsing it under warm running water. Make sure that the filter is completely dry before putting it back into the chainsaw.

Keep the chainsaw chain sharpened and ready to go. Using a chainsaw with a dull blade increases the risk of severe injury to the operator or those around them, as well as increased wear and risk of damage to the chainsaw.

Pro Tip: Keep an extra chain on hand so you are not tempted to use the chainsaw with a dull chain.
