While running, make the following checks to see that all
parts are working correctly.
B Radiator Cooling water(Coolant)

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 water 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 fin and tube;
4. Check to see if the fan belt is too loose;
5. Check to see if radiator water pipe is clogged;
6. Check to see if anti-freeze is mixed into coolant in
warm seasons.
B Oil 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.)
2. Lubricant system (See "ENGINE OIL" in "PERIODIC
SERVICE" section.)
1. Return the speed control lever to low
idle, and run the engine under idling
conditions.

"SWITCHED OFF" position, remove the
key. (Be sure to return the engine stop
lever to the "START" position to be
