If An Airflow Alert Activates
The most common causes of an Airflow Alert are:
• Blockage of the inlet grilles or exhaust outlet.
• Removal of the work surface or grille during operation.
Resetting the Airflow Alert System
The Airflow Alert automatically resets to normal operation once the motor
speed has stabilized.
