H codes generally refer to a hydraulic switch being closed when starting the unit up. Newer units are followed by a number such as H1, H2, etc......which tells you which switch it is....H1= Lift switch H2=Tilt switch....etc.......

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
