The carburetor is an essential part of the engine and should be adjusted by a dealer with professional knowledge, data, and equipment. Changing the carburetor when working at high altitudes: The atmospheric pressure may reduce the amount of air that carburetors intake when running in high-altitude areas. This may cause its performance to decline and increase fuel consumption. It may also affect the spark plug and make the engine hard to start. If at an altitude different from when the engine was certified, emissions may increase over an extended running time. Modifying the carburetor may improve its high-altitude performance. If you continuously operate your generator above 3281 feet (1000 meters), contact your after-sales service dealer, who can modify the carburetor.
Turn the maintenance cover knob to open, take off the maintenance cover and check whether the positive and the negative wires of the battery are connected correctly.
