Skin mesh renderrer is bigger than the model

I imported a model I made with a bone system and animation baked to it from 3DS max. However the bone system is on the 0,0,0 axis but the pivot for the model is not 0,0,0 in unity? How can I fix this? Also the skin mesh renderrer for the model is 10 times bigger than the model itsself, again how do I fix this? Help for this would be greatly appreciated. :)
