Deere 27D......my first excavator

So I've just picked up my first excavator, mostly for personal use. Its for 2600 hours, new tracks, some new hydraulic lines, an 18" dig and 36" smooth edge buckets, and seems to be in reasonable condition for an 09.

All the other equipment I own came with manuals, so I'm trying to source manuals for the 27D. I see there is an operators manual and a service manual. I'm would assume the operators manual covers maintenance and the service manual covers overhauls?

I've only owned steel...
