regulation indicator will light up and the
buzzer will sound.
• For Premium KVT models:
– If the cooling water temperature is 0
℃
(32
℉
)
or below and the transmission oil
temperature is -7
℃
(19
℉
) or more, the
engine low temperature regulation indicator
will light up and the buzzer will sound.
– If the cooling water temperature is 0
℃
(32
℉
)
or below and the transmission oil
temperature is also -7
℃
(19
℉
) or below, the
engine low temperature regulation indicator
and
transmission
low
temperature
regulation indicator will alternately light up
and the buzzer will sound.
– If the transmission oil temperature is -7
℃
(19
℉
) or below when engine low
temperature regulation has been released,
the buzzer will stop but the transmission oil
low temperature regulation indicator will
remain lit.
4. DEF/AdBlue
®
freeze warning
When operating in cold weather, the DEF/AdBlue
®
is
automatically thawed while the engine is running.
However, in weather conditions of under -30
℃
(-22
℉
),
the DEF/AdBlue
®
cannot be completely thawed and
thus, an error/warning code
[P208B]
appears on the
instrument panel’s LCD screen.
If the error/warning code
[P208B]
appears on the
screen, stop the engine and restart it after 10 seconds.
After restarting the engine, the error/warning code
[P208B]
will disappear and the thawing of the DEF/
AdBlue
®
will resume.
In case the error/warning code
[P208B]
remains on the
screen even after restarting the engine several times,
contact your local KUBOTA Dealer.

STOPPING THE ENGINE
1. After slowing the engine to idle, wait 3 to 5 minutes
for turbo to slow down and then turn the key to
“OFF”
.
2. Remove the key.
NOTE :
• If removing the key does not stop the
engine, consult your local KUBOTA Dealer.
• After turning the key switch to “OFF” and
stopping the engine, the SCR system
automatically begins to cool off the system
and extract DEF/AdBlue
®
from the lines.
Operating sound may continue to be heard
from the SCR system (for example, from the
DEF/AdBlue
®
tank or DEF/AdBlue
®
pump)
after stopping the engine, but this is the
operating sound of the SCR system and not
an abnormal sound.
WARMING UP THE ENGINE
WARNING
To avoid personal injury or death:
• Be sure to set the parking brake during warm-
up.
• Be sure to set all shift levers to the “NEUTRAL”
positions and to place the PTO lever in the
“OFF” position during warm-up.
For 5 minutes after engine start-up, allow the engine to
warm up without applying any load; this is to allow oil to
reach every engine part. If load should be applied to
the engine without this warm-up period, trouble such as
seizure, breakage or premature wear may develop.
1. Warm-up and transmission fluid at
low temperature range
Hydraulic oil serves as transmission fluid. In cold
weather, the oil may be cold with increased viscosity.
This can cause delayed oil circulation or abnormally
low hydraulic pressure for some time after engine start-
up. This in turn can result in trouble in the hydraulic
system.
To prevent the above, observe the following
instructions:
Warm up the engine at about 50% of rated rpm
according to the following table:
