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.

DC PROTECTOR

The DC protector turns off automatically when electric
device being connected to the generator is operating
and current above the rated flows. To use this equip-
ment again, turn on the DC protector by pressing its
button to "RESET".
1 "RESET"
Direct current is output. (This is the default position.)
2 "OFF"
Direct current is not output.
NOTICE
Reduce the load of the connected electric device
below the specified rated output of the generator if
the DC protector turns "OFF". If the DC protector
turns "OFF" again, stop using the device immedi-
ately and consult a Yamaha dealer.
