SPS,
As Rotorque says, the (POH) reason you are pulling the tail down is to check the tail rotor Flex Coupling. Any other checks you may be able to do whilst there are a bonus.
Personally, I find that I have so much going on holding the tail down, rotating the TR, trying to keep clothes and arms away from it, counting bolts on the Flex Coupling etc etc, that I prefer to check the other stuff mentioned by RW-1 with the beast resting back on its skids.
