If you happen to purchase a battery or corded lightweight hedge trimmer, you’ll be glad to know that it does not require as much maintenance as a gas-powered trimmer. With battery and corded powered trimmers, you’ll need to maintain the blade to ensure it is still very sharp and has no signs of rust. To prevent this, ensure you use a clean cloth to wipe off the debris from your blades. You’ll also want to keep this in a safe, dry place, one that is far away from children and animals because of its very sharp blades.
