When the economy control switch is turned to “ON” 1,
the economy control unit controls the engine speed
according to the connected load. The results are better
fuel consumption and less noise.

the engine runs at the rated r/min (4,500 r/min) regard-
less of whether is a load connected or not.

when using electric devices that require a large starting
current, such as a compressor of a submergible pump.
