Your shredder needs to be lubricated periodically. I've seen recommendations that it be lubricated after each 1/2 hour of continuous shredding. Commercially available lubrication sheets cost about $1.00 each. You can make your own for less than 13 cents. This video will take you through the process in just 2-1/2 minutes.
