(3) WATER TEMP (Coolant Temperature) Warning Indicator (High Water Temp.)
CAUTION: BURNS
 Do not open the radiator cap immediately after stopping the engine.Do so will result in
hot steam gushing out.
 Hot steam gushes out from the coolant sub-tank if the generator overheats. Do not
touch the coolant sub-tank.
If the coolant temperature rises above 212°F(100℃) during operation, the WATER TEMP
warning indicators 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 2070rpm during operation, the OVER SPEED warning indicators and ENGINE warning
indicators 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) AIR FILTER (Air Cleaner Clogging) Warning Indicator
The AIR FILTER warning indicator illuminates if the air cleaner element becomes clogged
during operation. If it illuminates, immediately stop the engine and clean or replace the air
cleaner element.
(Refer to section "10. Inspection/Maintenance (4) Air Filter Element Cleaning/Replacement".)
(6) SPILL CONTAINMENT (Spill Containment Amount) Checking Indicator
The SPILL CONTAINMENT checking indicator illuminates if the liquid
stored in the spill containment exceeds approximately about 33gal
(125 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 (15) 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, cooling water and DEF leakage, and repair as necessary.
 Do not use the equipment with liquid accumulated in the spill containment. Drain the spill
containment before using.
