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 shredding material when:
• Screen holes are too fine—overheating of the shredded material can occur.
• Screen holes are too course—shredded material can have larger pieces that
are unacceptable.
Standard Screen and Hydraulic Screen
Please refer to the section “Emptying the Screen” in Chapter 4.
V-Belts
V-belts are wearing parts that stretch and must be re-tensioned. Regular checks on the
tension force of the V-belts and the condition of the V-belts are necessary in order to
guarantee a long service life.
