Case 1825B - new owner maintenance tasks to complete?

Picked up a super-clean 1825 to do some light dirt work/grading for our acreage. Skids tend to bring a premium here in AZ, so I had a hard time parting with $8k for a miniskid. Current owner had it for 10 years, put about 200 hours on it, always garaged. Has 580 hours on it, and sitting in it you wouldn't think it was more than a couple years old: all the decals, plastics, seat, manuals, etc. are in great condition. The owner also had some acreage and was able to put it to task for about 30 minutes to check performance. A little moisture on top of the valve cover (poss. diesel leaking?), the rest of the hoses, hydraulics, pins, etc. were tight an leak-free. To my surprise, it had the pedals for the aux. hydraulics, and when I asked the seller about it, he scared up two hard lines that were removed and showed me where he capped/tucked away the rubber hoses coming from the aux. spool, so I'll need to spend some time re-installing those. So, my question is what kind of initial maintenance should I look to complete? Was going to go around and hit all the zerks with some grease, filters, oil... anything else? Also, any way to definitively tell what year this Case is? Serial is JAF0310836 but nothing on the serial tag or documentation that says otherwise. Thanks!

According to Coleman's data yours is a 2001. Which makes the PO's hours history possible. Good luck with your new machine. SimS
