Section 4 Functions of operating components
④
Overheat/engine oil pressure
warning buzzer
The overheat/engine oil pressure warning buzzer
warns rise of engine water temperature and drop
of engine oil pressure.
<Overheat warning>
When the engine water temperature rises and
the pointer of the water temperature meter
reaches the [H] position, the warning buzzer
sounds. If the buzzer sounds during operation, it
indicates overheat. In such a case, keep the
engine at the idling speed for 5 to 10 minutes to
cool the engine and then stop the engine.
<Engine oil pressure warning>
This warning functions in the same way as the
engine oil pressure lamp.
When the key switch is turned to the [ON]
position, the warning buzzer sounds. When the
engine starts, the engine oil begins to circulate
and when the pressure reaches the normal value,
the buzzer stops.
If the warning buzzer starts to sound during the
operation, and the needle of the water
temperature meter is not at the [H] position, it
indicates the engine oil shortage or dropped
pressure. Stop the engine immediately in such a
case.
