Chainsaws are portable, mechanical saws and they are generally used for felling trees, bucking, pruning, and harvesting of firewood. They have some teeth-like structures attached to the blade of the saw. Those structures are connected via a chain whose function is to rotate and slide along a guide bar. Here’s what you need to know about chainsaws. Chainsaw variations based on power. Gasoline-powered chainsaws are powerful and quite mobile, hence easy to handle. Available in both light-duty and professional-grade versions, the former can be used for operations that don’t involve much power. And the latter is used for heavier operations like felling trees. Electric Chainsaws are much suitable for smaller and lighter jobs like pruning and trimming. The electric chainsaws are highly preferred for household gardening purposes as they are quieter, easy to start and available as both corded and cordless. Battery-powered chainsaws are powered by batteries, and due to the batteries housed in the tool, the tool might be heavier. However, the best things about the battery-powered ones are that they are easy-to-start and quite portable. Hence, for professional heavy-duty purpose, gasoline powered chainsaws would do justice while for light-duty gardening activities an electric chainsaw would be an intelligent choice.
