Using the DeWalt DCHT870B hedge trimmer is a breeze. First, make sure you have a compatible 60V MAX* battery (sold separately). Insert the battery into the trimmer and ensure it's properly locked in place. When you're ready to start trimming, hold the trimmer firmly with the wrap - around auxiliary handle for a comfortable and secure grip. Start the trimmer and gently guide it along the hedges, bushes, or small branches you want to cut. For the best results, move the trimmer steadily and smoothly. Remember, the blade has a 1.25 - inch cutting capacity, so don't try to cut branches that are too thick. As for safety, always wear protective gear like gloves and safety glasses. Keep your hands and fingers away from the blade at all times. When you're done using the trimmer, remove the battery to prevent accidental starts. To maintain the trimmer, clean the blade regularly to remove any debris. You can use a soft brush or a cloth. If the blade gets dull over time, you may need to replace it. Store the trimmer in a dry and cool place to keep it in good condition.
