(AdBlue), check the odor of the DEF (AdBlue) in
the DEF (AdBlue) tank once every 3 months.
• If the DEF (AdBlue) in the DEF (AdBlue) tank
emits a strong ammonia odor, drain all DEF
(AdBlue) from the DEF (AdBlue) tank into a
container.
Details regarding how to drain the DEF (AdBlue)
can be found in a different section.
(See Draining DEF (AdBlue) on page 48)
After draining the DEF (AdBlue), flush the inside
of the DEF (AdBlue) tank with distilled water.
Then refill the DEF (AdBlue) tank with new or
high-quality DEF (AdBlue).
• If you do not use the machine for more than 3
months, drain all DEF (AdBlue) from the DEF
(AdBlue) tank. When using the machine after 3
months of inactivity, fully refill the DEF (AdBlue)
tank with new or high quality DEF (AdBlue).
NOTE :
• DEF (AdBlue) of deteriorated quality may cause
a drop in engine output or an engine
malfunction.
• If distilled water is not available for flushing the
inside of the DEF (AdBlue) tank, rinse with
clean water first, then rinse thoroughly with
DEF (AdBlue) again. Afterward, replenish with
new or high-quality DEF (AdBlue).
• Be sure to turn the starter switch to [STOP]
position when replacing the DEF (AdBlue).
• When draining and refilling the DEF (AdBlue) in
the DEF (AdBlue) tank, if the refilled amount is
less than the drained amount, an SCR system
error is displayed on the instrument panel, but
this is not a malfunction.
(See Draining DEF (AdBlue) on page 48)
10. Disposing DEF (AdBlue)
Although not a hazardous substance, dispose the used
DEF (AdBlue) properly to avoid environmental
pollution. For disposal methods, consult your supplier
or an industrial waste disposal contractor.
11. Handling precautions after
stopping the engine
After stopping the engine, the SCR system
automatically operates for up to about 25 minutes and
returns the DEF (AdBlue) in the piping to the DEF tank
to prevent freezing and clogging.
The SCR system may generate operating noise after
the engine has stopped, but this is not a malfunction.
Note the following precautions after stopping the
engine:
• Do not remove the battery terminal until the SCR
system stops. This is to prevent damage to the
system device.
• Do not refill with DEF (AdBlue) before the SCR
system stops. Otherwise, DEF (AdBlue) may
overflow from the breather hose of the DEF
(AdBlue) tank.
12. Precautions when using in cold
regions
• DEF (AdBlue) freezes below -11 ℃ (12 ℉ ), but this
does not affect the start-up of the engine.
• The DEF (AdBlue) is automatically thawed while
the engine is running.
• While thawing, output may be limited to protect the
SCR system.
• However, in weather conditions of under -30 ℃
(22 ℉ ), the DEF (AdBlue) cannot be completely
thawed and therefore, an error/warning code
(
“E:9517”
) appears on the instrument panel.
• If the error/warning code (
“E:9517”
) appears on the
screen, stop the engine and restart it after 10
seconds. After restarting the engine, the error/
warning code (
“E:9517”
) will disappear and the
thawing of the DEF (AdBlue) will resume.
• If the error/warning code (
“E:9517”
) remains on the
screen even after restarting the engine several
times, consult your local KUBOTA Dealer.
13. Maintenance of SCR system
related parts
Regularly check, clean, and replace the SCR system
related parts.
Details regarding maintenance can be found in a
different section.
(See MAINTENANCE on page 88)
14. SCR system warning lamp
This lamp serves to indicate that the SCR system is
having troubles. If this lamp lights up, check the error
code onscreen and follow the instructions given in LIST
OF THE ERROR CODE NUMBERS on page 131.
