METHOD FOR STOPPING ENGINE
k k
WARNING
Keep away from the exhaust pipe immediately after stop-
ping the engine.
NOTICE
• Do not stop the engine abruptly except in an emergen-
cy. Otherwise, the service lives of component parts of
the engine will be reduced.
If the engine is overheated, do not try to stop it abrupt-
ly but run it at medium speed to allow it to cool down
gradually, and then stop it.
• If the engine is stopped during the aftertreatment devi-
ces regeneration, the components may be damaged.
While the aftertreatment devices regeneration is being
performed, stop the aftertreatment devices regenera-
tion first according to “PROCEDURE FOR AFTER-
TREATMENT DEVICES REGENERATION DISABLE
SETTING”, run the engine at low idle for approximately
5 minutes, and then stop the engine.
REMARK
If the starting switch is turned to ON position or START position soon after the engine is stopped, the engine
coolant temperature gauge may point the red range momentarily. This is not a problem.
1.
Run the engine at low idle for approximately 5 minutes to cool down the engine gradually.
2.
Turn the key in starting switch (1) to OFF position (A), and
stop the engine.
3.
Remove the key from the starting switch (1).
REMARK
When the key in starting switch (1) is turned to OFF posi-
tion (A), the engine stops but the power supply to the ma-
chine is not turned off immediately.
The controller terminates the system after recording the
operation state of the machine. While this process contin-
ues, the main power is maintained.
The time to keep supplying the power depends on the op-
erating condition of the machine.
