Continuous Running Time - Yamaha EF3000iSE New Model Manual

Economy switch ON : 2800 rpm (with no load)
Economy switch OFF: 3550 rpm
The engine will run at 2800 rpm with economy switch turned on, if the electrical consumption is below 1/4
of its rated output.
When a light and electric motor are connected to the generator at the same time, turning one of the devices on
and off causes a change in voltage and could have an adverse effect on the other device.
In these kinds of cases, first turn the economy switch off before use.
Throttle valve operation:
I The throttle valve is fully opened when the engine is not running.
I When the engine is started with no load, the throttle valve will be set in an almost completely closed
position as soon as the engine is started.
(When the economy switch is "ON", it will be in a position to maintain 2800 rpm.)
I The engine speed will be adjusted according to the requirements of the load on the system.
I The throttle stops at the fully opened position when the engine is turned off in order to prepare for the
next attempt to start the engine.
In temperatures of zero degrees or below, the engine will automatically run at 3550 rpm for three minutes for
warming up purpose, even when the economy control switch is turned ON.
