FAQs document shredder
The cutting unit should be oiled if cutting performance decreases, a sound develops and after emptying the paper container. Inject the special oil over the entire width of the feed slot onto the blade shafts. Then, press the "R" key to reverse the cutting unit until all paper residues are released. The oiling of cutting units with strip cut improves the cutting performance and avoids squeaking noises resulting from jammed paper residues.
