Do not touch the coolant sub-tank.
If the coolant temperature rises above 230 °F during operation, the WATER TEMP and
ENGINE warning indicators light up, and the engine automatically stops. 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 and inspect for
these problems.
< NOTE >
Thecoolant temperature cannot bedetected if thecoolant levelisexcessively low.Alwaysbe
sure to check the coolant level inthe radiator coolant sub-tank before starting work.
(2) OIL PRESS (engine oil pressure) Warning Indicator (Low Oil Press.)
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 gauge or
oil filler cap during operation will result in hot oil gushing out.
If the engine oil pressure drops below 7 psi (0.49 x 100 kPa) during operation, the OIL
PRESS and ENGINE warning indicators light up, and the engine automatically stops. If this
occurs, check the engine oil level and add engine oil until it reaches the maximum level.
< NOTE >
This oil pressure warning indicator cannot detect oil deterioration. Changetheengineoil
periodically. (Refer to section “8-1. Checking Engine Oil”.)
CAUTION : BURNS
Do not touch the engine and surrounding components immediately after
stopping the engine as they are still hot.

11
(3) 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
rises above 2070 rpm during operation, the OVER SPEED and ENGINE warning indicators
light up, and the engine automatically stops. If this occurs, it is probable that some
malfunction has occurred in the engine. Contact the authorized distributor where the
generator was purchased.
(4) BATTERY (Battery Charge) Warning Indicator (Low Battery Voltage)
The BATTERY warning indicator lights up when charging is not possible during operation. If
charging is not possible and the battery voltage drops below 8 V, the ENGINE warning
indicator also lights up and the engine automatically stops. If this occurs, contact the
authorized distributor where the generator was purchased.
< NOTE >
This battery charging warning indicator cannot detect battery deterioration or insufficientbattery
fluid. (Refer to section “8-7. Checkingthe Battery”.)
(5) AIR FILTER (Air Cleaner Clogging) Warning Indicator
The AIR FILTER warning indicator lights up if the air cleaner element becomes clogged
during operation. If it lights up, immediately stop the engine and clean or replace the air
cleaner element.
(Refer to section “10. Inspection/Maintenance (3) Air Filter Element Cleaning/
Replacement”.)
(6) SPILL CONTAINMENT (Spill Containment Amount) Warning Indicator
The SPILL CONT warning indicator lights up if the liquid stored in the spill containment
exceeds approximately 10 gal. during operation. If it lights up, immediately stop the engine
and flush the liquid stored in the spill containment.
(Refer to section “10. Inspection/Maintenance (8) Flushing Liquid in Spill Containment”.)
< Note >
Theengine may not be stopped only if the spill containment warning Indicator illuminates during
operation.
When the spill containment warning Indicator illuminates during operation, stopthe engine, check
for fuel, oiland cooling water leakage, andrepair as necessary.
Do not use the equipment with liquid accumulated inthe spillcontainment. Drain the spill
containment before using.
(7) ENGINE (Engine Malfunction) Warning Indicator
The ENGINE warning indicator lights up if the coolant temperature is high, the oil pressure is
low, the engine overspeeds, the battery voltage is low or some other engine fault occurs
during operation. If this occurs, a malfunction code is displayed on the engine and available
output monitors, and the engine automatically stops or the engine output is reduced.
If the ENGINE warning indicator lights up, contact the authorized distributor where the
generator was purchased.

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.
WARNING : INJURY
Do not open the check door during operation. Be careful of pinching or
catching of moving parts such as the cooling fan and fan belt.
Always be sure to stop the engine and remove the starter key when
performing inspection or maintenance.
CAUTION : BURNS
Do not touch the engine and surrounding components immediately after
stopping the engine as they are still extremely hot.

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 as 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 torain entering intothe generator.
Accordingly, you shouldperiodicallyflush liquid accumulated within thegenerator. However, you
should flush water according to the frequency/amount of rainfall.
Thetypes of liquids that can accumulatein thespill containment includeoil, fuel, coolant and
batteryfluidsuchthat it isnotpossibleto distinguishbetweenrainwaterandother liquids. Dispose
of flushed liquids according tothe applicable laws andregulations.
5-6. 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
Change the lever of the three-way fuel valve is turned to the “A” side to supply fuel from
