Using these accessories for your Cutting Edge Saw™ is easy. When installing a blade, make sure the saw is turned off and unplugged. Align the blade properly and secure it tightly. For the battery, insert it firmly into the saw until you hear a click. When charging, use only the provided charger BNCE - 24VCHGR. Keep in mind to store the battery in a cool, dry place. After each use, clean the saw and blades with a soft cloth to remove any debris. Check the blades regularly for wear and tear, and replace them if they are damaged. This will ensure your saw works at its best and lasts a long time.
