A chainsaw is a powerful tool used to cut, fell, trim, and shape wood, commonly for tasks like cutting down trees, pruning large branches, preparing firewood, and clearing fallen or storm-damaged timber Using a chainsaw safely starts with wearing proper protective gear and checking that the chain, oil, and safety brake are in good condition. Always start the saw with the chain brake engaged and hold it firmly with both hands while cutting. Use the lower part of the bar, avoid the tip to prevent kickback, and let the chainsaw do the work without forcing it. Keep a stable stance, stay clear of others, and switch off and clean the saw after use.
