When I first discussed it with him (8-9 years ago) his position was that this was not a user adjustment and touching it would invalidate the warranty. I can't imagine why, it's easy and really can't hurt anything if done properly (which the manual should explain).
OTOH, I can't imagine that bending the armpost shouldn't invalidate the warranty (Really? Who would do that?). Very strange advice.
