Using your DeWalt DCHT870T1 hedge trimmer is easy. First, make sure the DCB606 battery is fully charged using the DCB115 charger. Once charged, insert the battery into the trimmer. Hold the trimmer with one hand on the main handle and the other on the wrap - around auxiliary handle for better control. You can then start trimming overgrown hedges and small branches. When trimming, move the trimmer slowly and steadily, letting the blade do the work. Try to keep the blade parallel to the hedge surface for an even cut. Remember, this trimmer has a cutting capacity of 1.25 inches, so don't try to cut branches thicker than that. For safety, always wear protective gloves and goggles. When you're done using the trimmer, put the sheath on the blade to avoid any accidental cuts. Store the trimmer in a dry place. To keep it in good condition, clean the blade after each use with a soft cloth. If you notice the blade getting dull, you can have it sharpened by a professional. Also, periodically check the battery for any signs of damage and charge it regularly even if you're not using the trimmer often.
