S650 Servicing?

[GTransport]

I am purchasing a 2012 Bobcat S650 with 2500 hours. It is at dealer, they 吐ully serviced it including ALL filters and engine oil. They do not have any service history on the machine so i asked them about replacing the chaincase oil, hydraulic fluid, coolant and a valve set. They told me the only time they change chaincase oil is if it becomes contaminated or a seal needs to be replaced. Hydraulic fluid he said they only do if the color becomes darker then its supposed to be. Does this sound true or should I make them do both? They dont want to cover the cost of a valve set, is this something people actually do every 1000 hours or only if it starts running rough? I would rather them not open up engine anyways if its not necessary. Thanks for any help!

Coolant 2 or 5 years depending on whats used (long life?) The book should tell you how many hours to change the hyd oil, chaincase oil, Valves idk on that I have seen truck engines wrecked by people adjusting valves wrong , I also would not want the engine opened up.....

Thanks for the reply, service manual states all those items at 1000 hour intervals. Im just wondering how many actually adjust the valves at that interval if its running smooth and not making any noise.
