DESCRIPTION OF DEVICE
Cooling water recirculation system
This system is to recirculate the cooling water without draining outside.
Accordingly, the engine does not have a cooling water drain hose.
Overheat prevention device
This device monitors the cooling water temperature with a water temperature
sensor. If the cooling water temperature reaches the setting temperature
(approximately 90
C) or higher, the warning buzzer alarms and automatically
stops the engine to prevent overheating.
･
Status of the lamp after the overheat prevention device is actuated.
①
If the engine is restarted while the main switch is being at RUN position,
the alarm lamp will turn on (an alarm buzzer will also sound).
②
If the engine is restarted after the main switch turned to STOP position
once, the alarm lamp will go off (reset). The alarm buzzer will not sound,
either.
･
Precautions for restarting after the overheat prevention device is
actuated
①
Resolve the cause of the abnormally high cooling water temperature,
and then restart the engine. If the cause of the abnormally high cooling
water temperature has not been resolved,
the engine will stop again
within approximately 30 seconds.
(The time in seconds until engine stop varies depending on the
temperature of the cooling water.)
②
The starter motor runs when the cooling water temperature exceeds
approximately 120
C, but the engine prevention function is actuated
and the pump cannot be restarted.
･
Do not repeatedly restart the engine without resolving the
cause of the abnormally high cooling water temperature.
