Controls and features

Ground (earth) terminal

Ground (earth) terminal connects the earth line for pre-

vention of electric shock.

When the electric device is grounded, be sure to

ground the generator, too.

For the grounding, consult a Yamaha dealer.

Economy control switch

In order to reduce fuel consumption and operating

noise, use the economy control switch.

“ ”/“ ” (ON)

When the economy control switch is turned to “ ”/

“ ” (ON), the economy control unit regulates the

engine speed according to the connected load. The

results are better fuel consumption and less noise.

“ ”/“ ” (OFF)

When the economy control switch is turned to “ ”/

“ ” (OFF), the engine runs at the rated speed (4900 r/

min) regardless of whether a load is 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 of a

submersible pump.

• Economy control does not function when the genera-

tor is in warming-up period (See page 4-1).
