As a Licensed Electrician which is the simplest way to replace the cord?
Welcome to the Bunnings Workshop community @Albonico. It's fantastic to have you join us, and many thanks for your question about repairing an electric shredder.
The process of replacing a damaged power cord is much the same with all machinery, tools and appliances. If you are a licensed electrician and are having difficulty accessing the machine to perform a repair, it would be best to contact Ryobi's technical assistance team directly via their Contact Us form.
Please let me know if you need further assistance.
