Query: Band won't stay in place

I received the trimmer the other day and found the instructions very lacking in information. When I barely touch my dog's toenail with the band the thing slides all over the place. The band seems tight until I try to trim my dog's nails. Of course, with no good instructions there isn't a way to find out how to correct this issue. Hopefully, someone out there that enjoys this tool can help answer this question.
