NH 575 baler questions

I just picked up a 575 and was wondering if it should have grease or some kind of lube on the bevel gears and bull gears in front of the knotters? And if they should be tighter mesh or not? The baler runs decent just a tick noisy there.
Im Sure I will habe a ton more soon. Thanks
