Using the DeWalt DCBL772X1 is easy. First, make sure the 20 V/ 60 V MAX* FLEXVOLT battery is fully charged. Insert the battery into the blower. Then, you can use the variable speed trigger to adjust the air output according to your needs. If you need a constant airflow, use the speed lock. When using the blower, keep it at a proper distance from the debris to get the best cleaning effect. For safety, always wear protective goggles and gloves. When it comes to maintenance, after each use, wipe the blower clean with a dry cloth. Store the blower in a dry and cool place. Check the battery regularly and charge it when needed. Also, inspect the motor and other parts occasionally for any signs of damage or wear.
