... about my new-to-me Clark C500 S60.

It appears we can't post images on this forum, not even clickable links? So I've posted them on my site and I'll just include links you'll have to copy/paste.

Is this the fill for the hydraulic tank? (workshopaholic.net/forumImages/_DSC6424.jpg) If so, how full should it be?

What do these two levers on the right do? (workshopaholic.net/forumImages/_DSC6425.jpg) When I push them, they're really stiff and I get some noises from somewhere under the front, but nothing seems to happen.

These two filters (workshopaholic.net/forumImages/_DSC6428.jpg) I'm thinking the one on the left is a hydraulic fluid filter and the one on the right is the engine oil filter?

Finally, what's the best jack point on the forklift? I see a couple of heavy cross-members across the bottom, is that my best bet?
