To continue,
Yes, the top of the stand where it contacts the frame can wear down, but mine was nearly all on the feet. Once I had them repaired, it was like a brand new bike, again!
With the stock stand, the front wheel needs to be up in the air a bit, so you have some space to rock forward. I learned that pretty quick as my stand wore down.
Another point to remember, is to NOT use the small tang as a pressure point when working it. That is for lowering to the ground, only!
After you have the stand down, move your foot to the left foot of the stand, and push from there. The tang will break off, if you use it for that.
Also, there are two allen-head screws that hold the stand to the frame. They are from the inside of the frame. The nuts on the outside. These should be checked for tightness once a year (at least), because they can some loose, and you will go to put your bike up on the stand one day, and it will fall over! (bad)
You will need to cut off part of a appropriate sized allen key wrench to fit into the tight space provided.
Besides the nut and the bolt, there is a top-hat spacer that the stand pivots on. Sometimes the stand will wear where it pivots on this point.
And then there are springs.......
