< NOTE >
If measuring the output current for a single-phase three-wire type, turn the ammeter selector
switch to “L1+U” or “L3+W”. The voltage cannot be accurately measured if set to “L2”.
Voltage Regulator/Engine Speed Switch
(1) Voltage Regulator
This dial is for regulating voltage output by the generator. Turn the dial
clockwise to increase the voltage and counterclockwise to decrease it.
(2) Engine Speed Switch
Throttle Switch
This switch is for changing the engine speed. Set to IDLING when starting,
warming up and cooling down the engine, and set to RUN during rated
operation.
5-4. Spill Containment
The bed of this generator is equipped with a spill containment (structure for preventing
leakage of liquids) so that any spilled liquid will not leak to outside of the generator when oil or
fuel is spilled or leaks. Before starting operation, check if there is accumulated liquid in the
spill containment. Flush out any liquid that has accumulated. Refer to section “8-5. Checking
the Spill Containment” for inspection procedures. Refer to section “10.
Inspection/Maintenance (8) Flushing Liquid in Spill Containment” for flushing procedures.
The generator is equipped with the following in order to prevent liquid from spilling in case you
forget to flush the liquid: The operation panel is equipped with an indicator that lights up when
its sensor is triggered when the spill containment capacity accumulated enough liquid to reach
the 1/4 full (approx. 10 gal.) level.
< NOTE >
Water can also accumulate in the spill containment due to rain entering into the generator.
Accordingly, you should periodically flush liquid accumulated within the generator. However, you
should flush water according to the frequency/amount of rainfall.
The types of liquids that can accumulate in the spill containment include oil, fuel, coolant and
battery fluid such that it is not possible to distinguish between rainwater and other liquids. Dispose
of flushed liquids according to the applicable laws and regulations.
5-5. Fuel Piping Switch (3Way Fuel Valve)
CAUTION:
Always make sure that the engine is stopped when working on piping.
Always be sure to wipe up any spilled fuel.
After working on the piping, check that there is no fuel leakage.
Change the three-way fuel valve to switch to supply fuel from the external tank. In that case,
the internal fuel tank is not used.
(1) If using the internal fuel tank:
The three-way fuel valve is turned to the “A” side when the generator is shipped from the
factory.
