You need to connect a frequency meter to the output of the unit.With no load on the genset, it should be running at about 62 Hz. If it is too low, adjust the engine speed up until it is running at 62 Hz, and this will bring the voltage up.But do NOT simply speed it up until it is putting out 120V. It is possible to get the frequency too high that way, and you can burn up anything you plug into the genset.
