The interval at which you should clean your shredder depends on how often you use it. At the latest, however, if you notice that the shredder makes a louder operating noise or works more slowly than you are used to, cleaning is advisable.To do this, you should first empty the collection container and apply the HP Shredder Oil in serpentine lines on a sheet of paper. Then feed the oiled paper into the shredder and, after it is completely shredded, press the reverse function for 10 seconds so that the cutting rollers are evenly oiled. Now your shredder is free of dust and paper residues and once again has an pleasantly quiet operating noise and provides an excellent shredding result.Do you regularly need a larger quantity ofShredder Oil?
