GOVERNOR
Governor Description
The governor is belt-driven, mechanically operated and maintains
engine RPM under varying conditions of generator load. The engine
speed determines the Hertz and voltage output of the generator.
NOTE: Belt tension: 3/8 - 1/2 inch deflection at center of widest
span with 22 lbs pressure applied to belt outer face. Maintain
belt tension for proper governor operation. Replace drive belt
when worn, frayed or cracked.
The governor will maintain engine RPM to within 3 Hertz of generator
frequency output from no load to full rated load of the generator.
