Hi Steve - If by some miracle you recieve this message, I have access to an old DV330 bandsaw and need to change the blade. I have searched online but I guess the model is so old that there is no support material available. I am wondering if I could ask you for the instructions from your manual or just send a copy of the pdf to my email (I will have to write out the address in slightly coded form with spaces instead of dots because this forum doesnt seem to allow emails to be included in messages). Email is: info "at" sfjnet co uk Many thanks for your help.

I have a PDF user instruction manual which I recieved from B&D support. If you have not resolved your problem, please leave another post here. I will then write out the relevant section for you.
