If any monitor lamp flashes, stop the engine or run it at low idling,
and take the following action.

If the temperature of the engine cooling water becomes abnor-
mally high, the monitor lamp flashes, and the overheat prevention
system is automatically actuated to reduce the engine speed.
Stop operations and run the engine at low idling until the engine
water temperature gauge enters the green range.
2. RADIATOR WATER LEVEL
If the radiator water level drops, the monitor lamp flashes. Stop
the engine, check the radiator water level, and add water if neces-
sary.
3. ENGINE OIL PRESSURE

monitor lamp flashes. At this item, stop the engine and inspect it

While the starting switch is ON, the lamp remains lit and goes
off once the engine is started. When the engine starts, the buzzer
may sound for a short time, however, this does not indicate a
fault.
