No oil in the box either. What kind of food grade lubricant can I buy? I can't really turn the handle at first, loose the bolt a little helps but only allow to turn outwards for 1/4; force it and some metal scraps feel off. Everything works fine afterwards but not as smooth as I expect....No there was no oil in the box. I have food grade lubricant on hand, tho. What parts of it get oiled?
