Using your DeWalt DWHT20545L 20 - foot standard panel hand saw is easy. Just grip the handle firmly and start sawing through the material you're working on. The three cutting surfaces will make the job go much faster compared to a traditional handsaw. When using it, make sure you're in a stable position to avoid any accidents. Also, don't force the saw too hard as the sharp teeth and low - friction coating will do most of the work for you. For maintenance, after each use, wipe the blade clean with a dry cloth. If it gets dirty, you can use a mild soap and water solution, but make sure to dry it thoroughly to prevent rust. Store the saw in a dry place to keep the blade and the coating in good condition. This way, your saw will stay sharp and perform well for a long time.
