6.1.4 Setting the height-adjustable seat post
 When using your seat post for the first time, you 
must give it a firm push downwards to set it in 
motion. This is due to the natural tendency of the 
seal to repel oil from the seal surface. You only 
need to do this before the first use or after a longer 
period of non-use. Once you have displaced the 
post through its deflection, the oil spreads on the 
seal and the post begins to function normally.
Crash caused by an excessively high seat post 
setting
A seat post with is set too high will cause the seat post 
or the frame to break. This will result in a crash and 
injuries.
 Do not pull the seat post out of the frame beyond 
the minimum insertion depth marking.
