MACHINE OPERATIONS AND CONTROLS
2.
Turn the key of starting switch (1) to OFF position (A), and
stop the engine.
3.
Remove the key from starting switch (1).
REMARK
• After the engine is stopped, DEF in DEF injector and
pump is automatically purged and returned to the tank
to prevent malfunction of the devices caused by freez-
ing of DEF or deposition of urea.
For this purpose, the devices keep operating for sev-
eral minutes after starting switch (1) is turned to OFF
position, and this does not indicate abnormality.
In addition, the system operating lamp lights up while
devices are operating to purge DEF to the tank. Do
not turn the battery disconnect switch to OFF position
while the system operating lamp is lit. After DEF has
been purged completely, the devices stop automatical-
ly.
• If the starting switch (1) key is turned to OFF position
(A) while the engine is still hot, guidance (2) may be
displayed on the machine monitor. To cool down the
engine before stopping, run it at low idle the next time
and after, because it may cause damage to the devi-
ces.
