WARNING: This function automatically stops
the engine. Take extra care on the work and work
environment when using this function.
IMPORTANT: If the machine is left unoperated in an
environment with temperatures under -20°C or lower
for a long period of time, exhaust gas particles may
accumulate in the aftertreatment device, and may
result in damage to the device.
In an environment with temperature of -20 °C or lower, the
engine will automatically stop 60 minutes after the pilot
control shut-off lever is pulled to the LOCK position. 30
seconds before the engine stop, the monitor displays "Engine
Shut-down soon. " message (1) and the indicator starts flashing.
The buzzer sounds once 30 seconds before shut-down, and
sounds continuously from 15 seconds. The engine speed
decreases to idling speed, and then stops after 15 seconds.
When the pilot control shut-off lever is pushed down before
stopping the engine, the auto shut-down is disabled and the
engine will not stop.
IMPORTANT: When the engine stops, turn the key switch
to ACC or OFF once and then turn it to START to restart
the engine. In the case the engine stops automatically,
turn the key switch OFF before leaving the machine for
a long period of time. Do not leave the machine after
auto shut-down. Failure to do so may discharge the
batteries.

NOTE: The engine can stop automatically when related
conditions are met regardless of the auto shut-down function
being ON or OFF.
