Additional considerations

In addition to the factors listed in the table, you may also want to consider the following when choosing a chainsaw:

• Chain type: There are two main types of chains: chisel and semi-chisel. Chisel chains are more aggressive and are better suited for cutting hardwoods. Semi-chisel chains are less aggressive and are better suited for cutting softwoods.
• Bar length: The bar length determines the diameter of the logs that you can cut. A longer bar will allow you to cut larger logs, but it will also be more difficult to maneuver.
• Fuel type: Chainsaw engines can run on gasoline or a mixture of gasoline and oil. Gasoline-only engines are more powerful, but they are also more expensive to operate. Gasoline/oil engines are less powerful, but they are more fuel-efficient.
