ENGLISH
STOPPING THE ENGINE 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; 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.)
BCharge lamp
The lamp lights up to warn the operator that the battery
charge is low. If this should happen during operation,
immediately stop the engine and check the following:
1. Cable broken
2. Poor connection at alternator terminal
3. Fan belt too loose or damaged
1. Return the speed control lever to low
idle, and run the engine under idling
conditions.
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.
2. The engine should stop with the starter
switch placed at the OFF position. (In
case of non-stopping, set the engine
stop lever to the "STOP" position
manually.)
3. After stopping the engine, remove the
key.(Be sure to return the engine stop
lever to the START position to be ready
for the next starting in case of manually
stopping.)
