There is only one published manual available for the DC07. It is available in paperback and you can get it from dysonworkshopmanuals.com - you should also be able to get it on Amazon. I have seen it on eBay too. The full title is: The Unofficial Dyson DC07 Workshop Manual: All you need to know to perform any DIY repair to your Dyson DC07 - the one with the girl and four or five DC07's on the cover.
