the prop pith lever has 3 positions: neutral, down (on which the propeller is going as coarse as long you'll kept it pressed), and upper (on which the propeller is going as fine as long you kept it pressed).
the prop pitch has an instrument on board, indicating between 8:30 (which is max coarse), and 12:00 (which is max fine).
taking off needs the prop to be set at 12:00., full throttle and WEP. For climbing the same.
After that, coarse the propeller's blades, together with throttling back (to a lower ATA) in order to keep the RPM indicator in the 2500 area.
