A If equipped with a turbo-charger, allow the engine to
idle for 5 minutes before shutting it off after a full load
operation.
Failure to do so may lead to turbo-charger trouble.
CHECKS DURING OPERATION
While running, make the following checks to see that all
parts are working correctly.
BRadiator cooling water (Coolant)
WARNING
To avoid personal injury:
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 pressure, before
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;
5. Check to see if radiator water pipe is clogged; and
6. Check to see if anti-freeze is mixed to a 50/50% mix
of water and anti-freeze.
