Checking the Cutting Head Chain Tension
Check the chain tension once every week in the first month, then once a month thereafter.
1. Switch off the shredder and unplug from wall outlet.
2. Remove the top right side cover.
3. The sagging of the chain (see Fig. 2) should be 9 - 14 mm, measured from the top inside of
the frame to the cutting head chain.
If it is not within this range, loosen the tension screws until the sagging reaches the
correct level. Retighten the tension nuts.
4. Replace the side cover, plug in the shredder.
NOTE:
Excessive tensioning of the chain can cause premature wear of the chain and bearings.
The smallest allowed chain sagging in the first month of operation is 5 mm. After that, 9 mm.
