Hi, Marg,
I looked for images and reviews on the internet and, the five year warranty makes me
think they must stand behind their product.
Perhaps you just got a bad set of blade clamps. One review I read stated they returned
two before they got the third one that was in good shape.
If it isn't too much of a hassle, I think I would call the company to pick this one up and
deliver another.
Good luck and God Bless! Spirithorse
