The bed of this generator is equipped with a spill containment (structure for preventing
leakage of liquid) so that any spilled liquid will not leak to outside of the generator when oil or
fuel is spilled or leak. 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 (10) 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 illuminates
when its sensor is triggered as the spill containment capacity accumulated enough liquid to
reach the about 12gal ( 45.4 liters ).
If the liquid stored in the spill containment exceeds approximately about 25gal ( 94.6 liters )
during operation, the SPILL CONTAINMENT overflow warning indicator illuminates, and the
engine will be automatically stopped. If this occurs, flush the liquid stored in the spill
containment.
(Refer to section “10. Inspection/Maintenance (10) Flushing Liquid in Spill Containment”.)
< Note >
Water can also accumulate in the spill containment due torain entering intothegenerator.
Accordingly, you should periodically flush liquid accumulated withinthegenerator. However, you
should flush water according to the frequency/amount of rainfall.
Thetypes of liquids that can accumulate inthe spill containment include oil, fuel, coolant and
batteryfluidsuchthat it isnot possible to distinguishbetween rainwaterand other liquids. Dispose
of flushed liquids accordingtotheapplicablelawsandregulations.

< Note >
If measuring theoutput currentfor a single-phase three-wiretype, turntheammeter selector
switch to “L1+U” or “L3+W”. The voltage cannot be accurately measured if set to “L2”.
(3) Frequency Meter
Displays the frequency of the power source. Check that 60 Hz is displayed during operation.
Indicators
(1) Pre-heating Indicator
The pre-heating indicator illuminates when the starter switch is
at PREHEAT. The pre-heating indicator turns off when
pre-heating is completed to indicate that it is possible to start
the generator.
< Note >
Pre-heating time depends on the coolant temperature, and
should becompletedinapproximately 0.5to8 sec.
(2) Pilot Lamp
This illuminates when the engine is operating to indicate that power is being generated.

Switches
(1) Starter Switch
STOP
The engine is stopped and all power is
shut off with this position. The key can
be inserted and removed only in this
position.
RUN/PREHEAT
Position for operating the generator.
It is also the position for glow plug
preheating for cold climate condition.
< Note >
Do not leave thegenerator in thisRUN positionwiththe enginestopped.
Doing so will cause thebattery to drain.
START
Position where the engine is started. If you remove your hand from the key, it returns to
RUN automatically.
(2) Breaker
This switch is for transmitting electrical power to the load side. Turn to ON position to output
voltage to the output terminals. Output to the load side is cut off when there is a short circuit
or overload on the load side.
< Note >
Do notturns off/onthebreaker manuallyto operate or stopa load.
(3) Breaker Trip Selector Switch
This switch is for selecting the tripping order of the three-phase and single-phase breaker
when there is a short circuit or overload on the load side. If the three-phase or single-phase
breaker is selected for precedence in tripping, the selected breaker will trip first when the
total generator output exceeds the rated capacity.
After that, the other breaker will also trip if the generator output exceeds the rated capacity
again.
Switch Selection
“3  1  ”: The three-phase breaker trips first followed by the single-phase breaker.
“Simultaneous (3  1  )”: The three-phase and single-phase breakers trip
simultaneously.
“1  3  ”: The single-phase breaker trips first followed by the three-phase breaker.
(4) Ammeter Selector Switch
This switch is for selecting the output current indicated by the ammeter. Change the switch
to display the following output terminal current on the ammeter.
Switch Selection
“L1+U”: Three-phase L1 phase + Single-phase three-wire U phase (total)
“L2”: Three-phase L2 phase
“L3+W”: Three-phase L3 phase + Single-phase three-wire W phase (total)

Voltage Regulator/Throttle 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) Throttle Switch
This switch isforchanging theenginespeed. SettoIDLING whenstarting,
warming up and cool down the engine, and setto RUN during rated operation.
5-7. 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 will not be used.
(1) If using the internal fuel tank
Change the lever of the three-way fuel valve is turned to the “B” side to supply fuel from
the internal tank. It is turned to the “B” side when the generator is shipped from the
factory.
< Note >
When disconnecting piping from the external tank, turn the lever to the “B” side, and attach the
bundledplug (R1/2”)totheexternaltank fuelinlet/return.
(2) If using an external fuel tank
Connect hoses from the external fuel tank to the external fuel inlet and the external fuel
return. Change the lever of the 3way fuel valve to the “A” side to supply fuel from the
external tank.
Refer to “9-6. Connecting with External Fuel Tank”for corresponding procedures.
