rust on feeder head on Komori 440p

hi, has anybody experienced a major rust problem on the feeder head of a Komori.
Our machine is 1 year old and we are no where near the sea,
(which is usually a factor in rust ) We do have a slight bit of moisture in the air but not
enough to cause such an amount of rust. Looking at the other Komori that we have
had in the shop for about 5 years longer than this new one I dont find any rust
whatsoever on the feeder head. I do know how to prevent further rust from occuring
but to me it is just strange to see the amount of rust on the newer model, especially
since the older one has never had any sort of rust treatment and both stand machines
about 40 meters apart.

 

Not to be silly, but any chance it is just some leftover preservative from the install?
