Frying the darker plastic cover open without damaging it is near impossible. I have a problem with my mouse wheel and I don't know how to lubricate it or fix the sensor. Can someone help with that?

These are bad instructions, the top is released with 3 clips accessible under the battery cover, prising it off from above will break those clips. It can be hard to work out where the clips are and how to release them, but there are 3 one on each side and on under the battery. Aside from that the only other retention is a couple of hooks on the mouse buttons.
