REMARK
• When the key in 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 because that the power is supplied for the con-
troller to save the operating condition and then finish
the system. The time to keep supplying the power de-
pends on the operating condition.
• If the starting switch key (1) is turned to OFF (A) posi-
tion while the engine is still hot, guidance (2) may be
displayed on the machine monitor. This may cause
damage to the devices. To cool down the engine grad-
ually before stopping, run it at low idle for approxi-
mately 5 minutes.
• 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.
The devices continue the operation for several mi-
nutes for this reason after the engine starting switch
key is turned to OFF position, but this is not abnormal.
Do not turn the battery disconnect switch to OFF posi-
tion while the devices are purging DEF. After the purg-
ing operation is finished, the devices stop automatical-
ly.

WARNING
• Check the direction of the track frame before operating
the travel lever and travel pedal.
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 checks.
• Clear any obstacles from the travel path.
• There is a blind spot at the rear of the machine, so be
particularly careful when traveling in reverse.
• Operate the levers carefully. The engine speed may
suddenly increase during the autodeceleration.
• When traveling, check that the travel alarm sounds
normally.
Screen on the machine monitor is automatically switched to the bird's eye view display of KomVision when trav-
eling.
