| 1. Clog in cartridge filter (in conveying line filter case) and drying filter. |
|
|
|
| If clogged, air will not circulate, potentially leading to overload to blower. |
 |
- Check to see if each filter is clogged.
- If dirty or clogged, blow clean dry air into filter and remove the clinging particles.
| [Point] |
| |
- Wear a mask when cleaning. Dust/particles will disperse in the air when blowing dry air.
