METERS
7. ENGINE WATER TEMPERATURE GAUGE
This meter (7) indicates the engine cooling water temperature.
During normal operations, the indicator should be in the black
range. If the indicator enters the red range during operations, the
overheat prevention system is actuated.
The overheat prevention system acts as follows.
Red range position (A): Engine water temperature monitor (1)
turns red.
Red range position (B): Engine speed is reduced to low idle,
engine water temperature monitor lamp (C) turns red, and the
alarm buzzer sounds at the same time.
The overheat prevention system remains actuated until the indi-
cator returns to the black range.
When the engine is started, if the indicator is at position (C),
engine water temperature monitor (1) lights up white.
In this case, carry out the warming-up operation. For details, see
"WARMING UP OPERATION (161)".
