ECONOMY IDLE SWITCH
When the economy idle switch is turned to "ON", the
engine speed is automatically reduced to idle when
the generator load is reduced to 0.8 A or less. The
results are better fuel consumption and less noise.
1 I “ON”
2 3 “OFF”
NOTE:
The economy idle switch must be turned to "OFF" to
increase engine speed to rated rpm when:
- using a load of 0.8 A or less.
- supplying AC 120V only from W with X.
