Important Usage Guidelines
Do not operate at maximum air pressure as airflow becomes too small and unsafe. Install intake filter to extend bearing life. Correct rotation direction is CCW. Avoid use in high temperature, high humidity, or strong magnetic fields. Use appropriate power supply for optimal performance.
