ECONOMY CONTROL SWITCH
1 I “ON”
When the economy control switch is turned to “ON”,
the economy control unit controls the engine speed
according to the connected load. The results are better
fuel consumption and less noise.
2 3 “OFF”
When the economy control switch is turned to “OFF”,
the engine runs at the rated r/min (3,800 r/min) regard-
less of whether there is a load connected or not.
TIP
The economy control switch must be turned to “OFF”
when using electric devices that require a large starting
current, such as a compressor or a submersible pump.
