Using the DeWalt DCBL722P1 handheld blower is easy. First, make sure the DCB205 5.0AH battery pack is fully charged with the DCB115 charger. Then, attach the concentrator nozzle if you need a more focused air stream. Hold the blower firmly and use the variable - speed trigger to control the power. You can lock the speed for continuous operation. When using it, keep it away from your body and other people. Don't point it at delicate objects as the high - speed air can damage them. After use, store the blower in a dry place. Periodically check the motor and the fan for any debris and clean them gently. Also, check the battery and charger for any signs of damage. With proper use and maintenance, your DeWalt blower will serve you well for a long time.
