12 OPERATING THE ENGINE

CHECKS DURING OPERATION

While running, make the following checks to see that all
parts are working correctly.
BRadiator cooling water (Coolant)
To avoid personal injury or death:
A Do not remove radiator cap until
coolant temperature is well below its
boiling point. Then loosen cap
slightly to the stop position, to
relieve any
removing cap completely.
If the coolant temperature warning lamp lights up or if
steam or coolant does not stop squirting from the radiator
overflow pipe, turn off the load and keep the engine
idling (COOLING-DOWN) for at least 5 minutes to let it
cool down gradually. Then stop the engine and take the
following inspection and servicing.
1. Check to see if the coolant runs short or if there is any
coolant leak;
2. Check to see if there is any obstacle around the
cooling air inlet or outlet;
3. Check to see if there is any dirt or dust between
radiator fins and tube;
4. Check to see if the fan belt is too loose; and
5. Check to see if radiator water pipe is clogged.
BOil pressure lamp
The lamp lights up to warn the operator that the engine oil
pressure has dropped below the prescribed level. If this
should happen during operation or should not go off even
after the engine is accelerated more than 1000rpm,
immediately stop the engine and check the following:
1. Engine oil level (See "ENGINE OIL" in "PERIODIC
SERVICE" section.)
BImmediately stop the engine if;
A The engine suddenly slows down or accelerates.
A Unusual noises are suddenly heard.
BIf MIL (Malfunction Indicator Light) lights
