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 compres-
sor of a submersible pump.
• Economy control does not function when the genera-
tor is in warming-up period (See page 4-1).
Power supply display
The current power supply level is displayed by the out-
put indicators. According to the power supply level, the
output indicator(s) will come on.
