Many people complain that the new “fancy” features on a lot of modern chainsaws lead to trouble down the road – they just don’t trust, need, or want the new offerings on the market.

This Jonsered CS2245 is highly rated, at nearly 5 stars. Boasting “no bells and whistles,” this chainsaw is designed to outlast and outperform even the most technologically advanced chainsaws on the market.

But don’t worry, you won’t be back in the stone ages with this chainsaw. It offers a Clean Power engine that reduces harmful emissions and increases fuel efficiency.

Jonsered CS2245, 18 in. 45cc 2-Cycle Gas Chainsaw
  • Clean power engine technology reduces harmful exhaust emissions up to 75% and increases fuel efficiency up to 20%, while providing raw power − even at low speeds.
  • Unique turbo intake air cleaning technology uses centrifugal force to separate and remove up to 97% of sawdust and dust particles from air before it reaches the air filter for optimal performance

Coupled with the turbo intake air cleaning system that removes sawdust from the air, your new machine will stay clean and working at maximum efficiency for longer.

When the time comes, it will be easy to clean the air filter and change the spark plugs as needed, no tools required, because of the snap lock cover design.
