Kawasaki's GE Series Generators come standard with many convenient features that you would only expect to find on the more expensive power plants. Overhead Valve Engines use less oil than older designs and feature a cast iron cylinder liner for extra long wear. Simultaneous AC and DC use allow you to charge a battery while operating AC equipment. The fuel level sight gauge allows you to check the fuel level at a glance. The dual voltage allows you to run 120v or 240v for special applications. The Automatic Voltage Regulator keeps AC voltage within specified limits. The voltmeter allows you to check the voltage output during operation. The low oil level warning / shutdown light flashes and engine stops if oil gets to low to prevent damage to engine. Low noise level is attributed to an efficient muffler and refined cooling and induction systems to lower sound levels.
