We are using quite often MAC 25 and more. During debording NW extends sometimes dramatically, but that's usually the case if loading stuff are emptying hod 2 and 1 first. Good indication on the 800 is the PSEU light which comes on if the NW strut extend too much, that's the point when I ask the loaders to do hold 3/4 first. I have never seen an 800/900 sitting on its tail. Anybody seen it?
