# Why is there dust building up in the hopper?

### Dust stored in hopper.

Remove dust continuously. The dust collector is not designed to store material. Dust buildup in the hopper reduces efficacy of the unit and may cause damage to the filter bags.

### Discharge device not running.

Verify that the discharge device is running properly. See recommended startup and shut down procedures.
