Hi,
Have just bought another 360 digger after my last one was stolen along with a plant trailer.
It is a komatsu pc20-6, I wondered if anyone could help me with a few questions?

What is the dipstick for in the cab, is it hydraulics, what level should it be at?
How high should the hydraulic oil be in the resevoir, at the minute it is right to the top?
What level should the oil be in the final drives? there are three ports at 120 degree separation.
What tracks should be on the machine? It is on rubbers at the minute, but they don't seem to fit the idlers properly.
Would too high level hydraulic oil affect the tracking speed, or have the final drive motors had their best days?

Many thanks to anyone who could shed any light on these for me.
