Tightening the feed belt

The feed belt should not slip when loaded with material.

•  Switch off the shredder.

•  Remove the feeding table and the left and 

right side covers.

•  Loosen the hexagon nuts (1) of the tension roll on the 

left and right side.

•  Loosen the lock nuts (2) of the tensioning bolts (3).
•  Tighten the feed belt 

evenly 

using the tensioning 

bolts.

Note:

Only tighten the feed belt until it stops slipping. The feed 
belt bearing may be damaged if it is tightened too much.

•  Tighten the hex nuts on the snub roller and 

the lock nuts on the tensioning bolts again. 
Reinstall the covers and the table.

You must check that the feed belt runs 
straight:

Switch on the shredder and let it run for 
10 minutes. During this time, the feed belt 
must run in the middle of the snub roller. If it 
slips to the left or right edge, you must alter 
the setting of the snub roller.

Checking the feed belt for wear

The surface of the feed belt can become worn after long 
periods of use. If you can see the fabric inlay in the belt, it 
must be replaced. Please notify our customer service.
