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:
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.
When the engine overheats and hot coolant overflows
through the radiator and hoses, stop the engine
immediately and make the following checks to determine
the cause of trouble:
Check item
1. Check to see 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.
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 Maintenance
Section).
2. Lubricant system (See "ENGINE OIL" in Maintenance
Section).
