Fellowes 62CM Powershed 10 sheet paperShredder only worked in reverse

My device is not the Fellowes T7CM but a Fellowes Powershed 62CM but I had to choose a device and that was the only choice available.

Does anyone have a wiring diagram for the 62CM papershredder.

We became owners of this machine when it failed to work in forward. We have attempted to repair it without a working diagram of the wiring without success. Can anyone assist here please?
