jcb210s backhoe need information

Just purchased 1995/6 jcb210s backhoe. Didn't come with any operators manual or any literature. Several switches on side dash I don't know what they do. Don't seem to do anything now. Only two lights come on when turn to ignition. Crab steer light and one other don't recognize what it is. No light for oil pressure or anything else. It seems to run fine and everything works but I would like to know a little more about it in regards to running it before I do any damage. Like shifting gears there is a button on the stick, also a button on the loader control that seems to stop the wheels when pushed, I also can't seem to release the backhoe to shift from one side to the other. I will have to fix the throttle from the side panel to the front as only the throttle pedal works so the when trying out the backhoe it is only idling. But I will get into that later as soon as it warms up outside.

Any help with some of these question would really be appreciated. Thanks.
