Fuel Gauge

The fuel gauge is a mechanical device that measures the fuel level in
the tank. The red indicator in the window will reference the level in
relation to full or empty. To provide increased operating time, start
with a full tank before beginning operation. Check the fuel level with
the generator on a level surface. Always refuel with the engine OFF
and cool.
