- Start Power Head: Start your Makita power head according to its specific instructions.
- Maintain Control: Hold the power head and attachment firmly with both hands. Maintain a balanced stance.
- Direct Airflow: Direct the blower nozzle towards the debris you wish to clear. Use a sweeping motion to move debris efficiently.
- Work Methodically: Work in sections, blowing debris into piles for easier collection.
- Avoid Obstructions: Be mindful of obstacles and delicate plants. Do not direct airflow at windows or vehicles.
- Shut Down: When finished, turn off the power head and allow the fan to come to a complete stop before setting the tool down.
