Common problems with Fellowes shredders include running continuously, failing to turn on, stopping suddenly while shredding, and operating in reverse only. To correct the problems, a person should either use the troubleshooting instructions found in the manual or call the customer service line at 800-945-4545 for help.
The shredder can fail to turn on because the safety interlock is not properly engaged. A shredder that is running continuously indicates that dirt or debris has covered its sensors, breaking signals between them. Stopping suddenly while shredding occurs because the shredder has jammed, or it has surpassed the maximum constant run time. An auto run sensor that is not engaged correctly causes the shredder to operate in reverse only.
