OPERATING THE ENGINE 32
COLD WEATHER STARTING
If the ambient temperature is below 0 (32 ) and the
engine is very cold, follow the procedure below after
taking the step 1 through 8 in the previous pages.
Heater indicator comes on when the key is turned to "ON"
position and engine coolant temperature is below 0
(32
), and goes off automatically when preheat is
completed.
A During a cold start, the low temperature regulation
indicator will appear on the LCD and the buzzer may
sound once every 2 seconds. In this case, the engine
speed will be limited to about 60%. If the operation is
continued, the engine speed limit will gradually and
automatically increase until the rotational speed will
match the Foot throttle (or Hand throttle) strength.
(If the engine fails to start after 10 seconds, turn off the
key for 30 seconds. Then repeat steps 9 and 10. To
protect the battery and the starter, make sure that the
starter is not continuously turned for more than 10
seconds.)
A
DEF/AdBlue® freezes at temperatures below -11
(12
). Even if it is frozen, the engine is not affected
at its start-up and running.
B Block Heater (if equipped)
A block heater is available as an option from your dealer.
It will assist you in starting your tractor when the ambient
temperature is below -20
(-4 ).
STOPPING THE ENGINE
A
When the engine is stopped-shutdown, DEF/AdBlue®
flow is reversed in the DEF/AdBlue® lines and related
piping and returned back into the DEF/AdBlue® tank
after cooling the DEF/AdBlue® injector.
The SCR system continues working several minutes
after engine shutdown to complete this purge process.
A Do not turn the machine main battery power off to the
engine until the DEF/AdBlue® return cycle purge
process is completed. Turning off the main battery
power to the engine and aftertreatment system prior to
completion may damage the system or cause it to
malfunction.
A
If key does not stop the engine, consult your local
KUBOTA Dealer.
