The height adjustment is covered in the operators manual, for moving the cutter disk closer to the fan.
The engine should be set to run in the full throttle position. The mower is not designed to raise further off the ground but to just barely float.
A test of this is to start the unit over clean smooth concrete or pavement, if the unit floats then the engine should be turning at the correct RPM. This can also be checked by your local authorized service center with a tachometer.
I can not answer how you motivate someone to use the mower.
