Replacing the Screen
The condition of the screen must be checked regularly in order to keep the throughput of
the shredder and the quality of the shredded material constant.
The screen may be damaged, dirty, or not suitable for the shredding material
when:
• Screen holes too fine—overheating of the material can occur.
• Screen holes too course—shredded material can have larger pieces that are
unacceptable.
Hydraulic Screen Support (optional)
1. Switch OFF the shredder at the main switch.
2. Safeguard main switch using a padlock.
3. Open the machine door.
4. Safeguard the machine door.
5. Pivot the screen support downwards by pushing the button screen open on
the control box.
6. Remove the screen.
7. Put a new screen into the screen support.
