Welcome to the Bunnings Workshop community. Thank you for joining us and sharing your question about product registration.
Product registration is one of the best ways to keep track of the details of your tool. The purchase details of your product are saved on the registration and if you ever need to claim for warranty the details are all there.
Brand new tools came with a user's manual and a warranty card. They usually indicate the website you need to proceed to in order to register your tool. You can also do a search for the name of the tool and from that company's website look for warranty or product registration.
If you can provide me with the name and model number of your laser unit, I will point you to the site where you need to register.
