I too agree with Jim on this one, i would be totally lost without my service and parts manuals!
For the price, seriously go buy one. They tell you just about everything you will ever need to know. It covers electrics, hydraulic system paths, fuel system, engine parts, some cover the pumps, motors, cylinders and more. It will tell you how to go about servicing too.
I bought mine off e-bay, they were all of what, 65 bux? plus shipping of course.
The parts manual helps when you need spares, you call Bobcat and quote a number and they get it for you. Rather than explaining what you need and getting the wrong part.
If you are going to keep the machine, do your self a favour and invest in the manuals, you won't be sorry.
