After 10-15 seconds of preheat, the control switch can be rotated to crank the engine. It is a good idea at this point to verify that water is exiting the exhaust. Allow the engine to warm for a few minutes before activating the Regulator. If the alternator is connected to a battery selector switch, be sure that the switch is on before activating the regulator. Normally, the engine is run until the batteries are charged, and then shut off.
Separate instrumentation is required to determine full charge on the batteries.
In many parts of the world, diesel fuel has a lower cetane rating than U.S. fuels. Even in the U.S. for our own diesels we use an additive regularly, and suggest that fuel be treated for the Genie with a diesel additive. These additives are extra refined oils that enable complete combustion and help to keep the engine injector clean. Some users report using a high grade two-cycle oil as an additive for low sulphur fuels typical in South America. Excessive smoking is often due to poor fuels, an overload on the engine, or insufficient fuel reaching the injectors.
