When I am using my shredder for long periods of time it begins to make a humming sound. Should I be concerned about this or can I keep using the shredder?

Different scenarios can cause the Fellowes T7CM paper shredder to produce a humming noise. In order to proceed with troubleshooting it is recommended that the device be opened up. Possible scenarios for the noise include lack of lubrication on the gears as well as gears being potentially broken.
