I only want to view the following, I do not want to download the whole manual. I have a Shark Stick Vacuum with cord Model NP 319 49. I purchased it at Target and did not get a Manual with it. I cannot get one tool off the end of the stick to replace it with another tool. Please e-mail me or tell me how to detach the one head and reattach another one. My email address is fran.miller@comline.com.
