That's probabily because the bones in the reference model are not rotated the right way. Did you bind the model to the Valvebiped Skeleton, or did you simply rename them?

Oh. This is my exported bones. I renamed them. How to fix this? I will be very glad if you help me. This is my first try to do own bones on source engine. This problem may reappear in the future with other people and they can check this discussion.
