Where I can find a service manual or spare parts?

HSM shredstar X8 - 3/16 x 1 1/8

Can you help with a service manual and/or a service advice?

Thank you!

Due to a wrong utilisation some paper were locked between shaft and plastic housing.

I have disassembled all the shredder and now I need to check how to assembly back.

If you can give me some drawings or video it will help me.

Thank you!
