The Role Of Dust Bag Capacity
One common issue with shop vacs is them shutting off unexpectedly. This often relates to the dust bag capacity. A full dust bag can cause the vac to overheat and shut down. Understanding how to manage your dust bag can keep your shop vac running smoothly.
Monitoring Dust Bag Fullness
Regularly check the dust bag’s fullness. A full bag can restrict airflow. This leads to the motor overheating. Create a habit of checking the bag after each use. Some shop vacs have indicators for bag fullness. If yours does, use it.
