rock saw/ polisher equipment help
I just acquired a rock saw/polisher from a friend of mine. it looks just like the one in the middle picture on the http://rockhounds.com/rockshop/manuals/ page of this website. It looks like there is used motor oil in the reservoir of the saw portion. I thought that water would be put in there. What really should be in the reservoir? I'm new to lapidary any advice would be greatly appreciated!
