Problem: Sieve problems
| Cause | Remedies |
|---|---|
| The powder hopper venting is too weak. | Increase the air mover setting or if defective, replace. |
| Mesh width of the sieve is too small. | Replace the sieve. |
| Waste bag | The waste bag of the rotary sieve machine should be slightly under- pressure. When it is too inflated the Airmover must be set higher. |
