I hope you can help me with some Japanese translation!

This is the instruction sheet from the Japanese seatpost for my bicycle. It’s one of the best and most expensive out there, partly because it’s infinitely adjustable.

The two bolts function BOTH as clamps for the saddle and a means to adjust the up and down tilt of the saddle. How do they do both? The guys at the bike shop say “Just play with it.” But I wonder what the instructions really say.

Thanks!
