5-3. Spill Containment
The bed of this generator is equipped with the 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 “8-4. 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 the SPILL CONTAINMENT
CHECKING indicator that illuminates when its sensor is triggered as the spill containment
capacity accumulated enough liquid to reach to about 4.2 gal (16 liters).
If the liquid stored in the spill containment exceeds approximately about 16.1 gal (61 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 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,
battery fluid and DEF such that it is not possible to distinguish between rainwater and other
liquids. Dispose of flushed liquids according to the applicable laws and regulations.
WARNING : INJURY
Do not open the check door when the starter switch is in the AUTO or START
position. It will cause injury by rotating parts such as cooling fans and fan belt.
Always turn the starter switch to the STOP position and stop the engine, then close

5-4. Warning Indicators
This generator is equipped with the following warning indicators: BATTERY (insufficient
charging), OIL PRESS (engine oil pressure), WATER TEMP (coolant temperature), OVER
SPEED (engine overspeed) and SPILL CONTAINMENT (spill containment amount). When the
engine starts, all the lamps will light off. Moving the starter switch from STOP to START
causes the BATTERY and OIL PRESS warning indicator to illuminate, and all of the indicator
lights will go off as the engine starts. An indicator illuminates if a malfunction/fault occurs
during operation and the engine automatically stops depending on the fault type (except for
SPILL CONTAINMENT).
If the generator automatically stops, move the starter switch to STOP and restart the engine.
Check each illuminated warning indicator at the time of automatic stop, and inspect the failed
component.
(1) BATTERY (Insufficient Charging) Warning Indicator (Low Battery Voltage)
The BATTERY warning indicator illuminates and the engine automatically stops when
charging is not possible during operation. If this occurs, contact authorized distributor where
the generator was purchased.
< Note >
This battery charging warning indicator cannot detect battery deterioration or insufficient
battery fluid. (Refer to section “8-6. Checking the Battery”.)
(2) OIL PRESS (Engine Oil Pressure) Warning Indicator (Low Oil Press.)
If the engine oil pressure drops below 14 psi (0.98 x 100 kPa) during operation, the OIL
PRESS warning indicator illuminates and the engine will be automatically stopped. If this
occurs, check the engine oil level and add engine oil until it reaches the maximum level.
WARNING : INJURY
Do not open the check door when the starter switch is in the AUTO or START
position. It will cause injury by rotating parts such as cooling fans and fan belt.
Always turn the starter switch to the STOP position and stop the engine, then close

CAUTION: BURNS
Always be sure to stop the engine and allow the engine to cool when performing
inspection or maintenance of engine oil. Opening the oil level indicator or oil filler cap
during operation will result in hot oil gushing out.

13
< Note >
This oil pressure warning indicator cannot detect oil deterioration. Change the engine oil
periodically. (Refer to section “8-1. Checking Engine Oil”.)
(3) WATER TEMP (Coolant Temperature) Warning Indicator (High Water Temp.)
If the coolant temperature rises above 239 °F(115℃) during operation, the WATER TEMP
warning indicator illuminates, and the engine will be automatically stopped. If this occurs, hot
steam will gush out of the coolant sub-tank. Check the coolant sub-tank coolant level after the
generator cools and add coolant to the coolant sub-tank if it is insufficient. (Refer to section
“8-2. Checking Coolant”.) If the coolant is at the specified amount, it is probable that the fan
belt is loose or there is a coolant leak. Wait for the engine to cool down and inspect for these
problems.
< Note >
The coolant temperature cannot be detected if the coolant level is excessively low. Always be
sure to check the coolant level in the radiator coolant sub-tank before starting operation.
(4) OVER SPEED (Engine Overspeed) Warning Indicator
This generator is equipped with a function such that the engine is automatically stopped if an
engine fault occurs causing the engine speed to increase excessively. If the engine speed
rose above 4,140 rpm during operation, the OVER SPEED warning indicator illuminates, and
the engine will be automatically stopped. If this occurs, it is probable that some malfunction
has occurred in the engine. Contact authorized distributor where the generator was
purchased.
(5) SPILL CONTAINMENT (Spill Containment Amount) Checking Indicator
The SPILL CONTAINMENT checking indicator illuminates if the liquid stored in the spill
containment exceeds approximately about 4.2 gal (16 liters) during operation. If it illuminates,
immediately stop the engine and flush the liquid stored in the spill containment.
(Refer to section “10. Inspection/Maintenance (10) Flushing Liquid in Spill Containment”.)
< Note >
The engine may not be stopped only if the spill containment checking Indicator illuminates
during operation.
When the spill containment checking indicator illuminates during operation, stop the engine,
check for fuel, oil and coolant leakage, and repair as necessary.
Do not use the equipment with liquid accumulated in the spill containment. Drain the spill
containment before using.
.
CAUTION: BURNS

usage. However, the pressure may rise above this range just after starting a cold engine.
Idle the engine until it reaches the normal pressure.
(3) Fuel Level
It shows the amount of fuel in the tank. All lamps are lit when the amount reaches to the
maximum level, and FULL is lit. The lit lamp decreases as the amount of fuel in the tank
reaches to EMPTY. The fuel level on the control panel will only display the fuel level for the
internal fuel tank.
Generator Meters and Gauges
(1) Voltmeter
The voltmeter displays the three-phase output
voltage (voltage between L1-L3). Check that 240 V
is displayed during operation. Output voltage for
single-phase three-wire (voltage between U-W) is
the same voltage as the three-phase output voltage
(voltage between L1-L3). Accordingly, use the voltage meter displayed value as a reference.
(2) Ammeter
Displays the output current (phase current) of the generator. Turn the ammeter selector switch
to “L1+U” to display the output current of the three-phase L1 phase and single-phase U phase.
Turn the switch to “L3+W” to display the output current of the three-phase L3 phase and
single-phase W phase. “L2” displays the output current of three-phase output terminal L2.
< 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”.
(3) Frequency Meter
Displays the frequency of the power source. Check that 60 Hz is displayed during operation.

Indicators
Check each illuminated warning indicator at the time of automatic stop, and inspect the failed
component.
(1) Pre-heating Indicator
The pre-heating indicator illuminates when the starter switch is
at START. The pre-heating indicator turns off when pre-heating
is completed. The preheating indicator turns off and the
generator starts.
< Note >
Pre-heating completes in approximately 5 seconds.
(2) Pilot Lamp
This lamp illuminates when the engine is operating to indicate that power is being generated.
(3) Over Crank Indicator / No Speed Signal
This indicator lights up if the engine fails to start. If that
happens, set the STARTER SWITCH selector to "STOP,"
and inspect the machine.
(Refer to section "12. Troubleshooting".)
If the LED light starts flashing, the rotation signal has not
been detected correctly. In that case, contact the authorized
distributor where the generator was purchased.
Switches
(1) Starter Switch
The engine warms up and starts automatically.
START
The engine is started in this position.
The engine warms up and starts automatically.
STOP
The engine is stopped, and the power supply
is turned off completely in this position. You
can operate the ACCESSORY switch in this
position.
AUTO
The engine is started in this position when the
REMOTE START terminal closes.
(2) Accessory Switch
If you select ON, the display turns on, activate the electromagnetic pump, you can check the
fuel level and you can bleed air from the fuel system.
< Note >
Set the STARTER SWITCH selector to STOP to activate this function.
Do not leave the ACCESSORY switch at ON position. This is causing battery from drain out.

(3) 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 not turn off/on the breaker manually to operate or stop a load.
(4) 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.
(5) 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)
< 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
(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.
