Droopy Blade

[Patrick M]

Hi Everybody.
I have a Sumitomo LS 1600 F2 excavator (LinkBelt if you are reading this in America) it has a problem with the blade lowering itself to the ground from maximum height in about 40 seconds, no obvious oil leaks showing anywhere at all, what do you think may be the problem?

could well be the rotary manifold(centre joint)

Had the same problem with a KX251 Kubota (8ton) machine, repaired the swivel joint and problem was gone.
