OPERATING THE ENGINE8
ENGLISH
COLD WEATHER STARTING
If the ambient temperature is below -5 C (23 F) and the
engine is very cold, start it in the following manner:
Take steps (1) through (2) above.
Heater indicator comes on when the key is turned to the
"ON" position and engine coolant temperature is below
0 C (32 F), and goes off automatically when preheat is
completed.
ADo not allow the starter motor to run continuously for
more than 20 seconds.
ABe sure to warm up the engine, not only in winter, but
also in warmer seasons. An insufficiently warmed-up
engine can shorten its service life.
AWhen the ambient temperature is expected to be
below -15 C (5 F), remove the battery from the
machine and move it to a warmer or heated and safe
indoor location. Reinstall the battery in the machine
just prior to the next machine usage. Do not store the
battery in living areas. Please observe Cautions
under section 8. in "SAFE OPERATION" of this
manual when working on or handling the battery or
personal injury and property damage may occur.
AWhen the engine coolant temperature is below 0 C
(32 F), the engine speed becomes temporarily
restricted. This is to protect the engine component
parts, especially turbo charger.
AA specific time later, the restrictive system gets
automatically released in stages.
ABasically the models are standard equipped with this
function. Some engine models are not equipped with
this, however.
STOPPING THE ENGINE
To avoid personal injury or death:
ATo stop the engine, be sure to use the
starter switch.
When shutting off the battery power
directly with the battery switch or the
like, first stop the engine with the
starter switch and then make sure
the ECU comes to a complete stop.
Otherwise a trouble or malfunction
may be caused
AAllow 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)
To avoid personal injury or death:
ADo not remove the radiator cap until
coolant temperature is well below its
boiling point. Then loosen the cap
slightly to the stop position, to
relieve any pressure, before
removing the cap completely.
CPrecaution at overheating
The event that the coolant temperature is nearly or more
than the boiling point is called "OVERHEATING".
While running, make the following checks to see that all
parts are working correctly. If anything is unusual,
inspect it, referring to the relevant description in
"MAINTENANCE" and "REGULAR CHECKS AND
MAINTENANCE WORK" section.
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 inspections 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 the
radiator fins and tubes;
4. Check to see if the fan belt is too loose; and check to
see if any one of the radiator water pipe is clogged.
3. Turn the key to the "ON" position and
hold it until the heater indicator turns off.
4. Turn the key to the "STARTING"
position and the engine should start.
(If the engine fails to start after 10 seconds, turn off
the key for 30 seconds. Then repeat steps (3) and
(4).
1. Run the engine under idling conditions.
2. The engine should stop with the starter
switch placed at the "OFF" position.
3. After stopping the engine, remove the
key.
