MACHINE OPERATIONS AND CONTROLS
REMARK
•
When engine starting switch (1) is turned to OFF (A)
position, the engine stops, but the machine's main
power supply is not turned off immediately.
This is a time lag provided for the controller to memo-
rize the operation status and then terminate the sys-
tem. While this process continues, the main power is
maintained. The power holding time varies depending
on the operation condition.
•
If the starting switch key is turned to OFF (A) position
while the engine is still hot, guidance (2) may be dis-
played on the machine monitor. To cool down the en-
gine before stopping, run it at low idle for approximate-
ly 5 minutes, because it may cause damage to the de-
vices.
•
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 up to 7
minutes after the key in the starting switch is turned to
OFF position, and this does not indicate abnormality.
Do not turn OFF the battery disconnect switch while
the devices are operating to purge. After the purge is
completed, the devices stop automatically.

•
Before operating the travel levers or travel pedals,
check the direction of the track frame.
If the track frame is facing the rear (if the sprocket is at
the front), the machine moves in the opposite direction
to the direction of the operation of the travel levers or
travel pedals (front and rear travel are reversed, right
and left steering are reversed).
•
Check that the area around the machine is safe, sound
the horn before starting the machine.
•
Prohibit anyone other than the operator from coming
close to the machine during operation.
•
Clear any obstacles from the travel path.
•
There is a blind spot at the rear of the machine, so be
particularly careful when travelling in reverse.
•
If the travel levers or travel pedals are operated when
the engine speed is decreased by the auto-decelera-
tion function, the engine speed will suddenly increase.
Operate the levers carefully.
•
When travelling, check that the alarm sounds normal-
ly.
•
When you operate the travel levers or travel pedals,
the screen will switch to the screen including bird's
eye view automatically.
