MACHINE OPERATIONS AND CONTROLS
PRECAUTIONS FOR HIGH SPEED TRAVEL
On uneven roadbeds such as rock beds or uneven roads with large rocks, drive the machine at Lo-speed. When
driving the machine at Hi-speed, set the idler in the forward direction.
•
Each time the travel speed selector switch (1) is pressed,
the travel speed changes repeatedly as Lo → Mi → Hi →
Lo. The travel speed (Lo, Mi, Hi) is displayed on the travel
speed display (2).
PERMISSIBLE DEPTH OF WATER, SOIL AND DIRT
NOTICE
When driving the machine out of water, if the angle of the
machine exceeds 15°, the rear of the upper structure will
go under water, and water will be thrown up by the cooling
fan. This may cause the fan to break. Be extremely careful
when driving the machine out of water.
Do not drive the machine in water or soil and dirt deeper than
the center of carrier roller (1).
After the job, be sure to supply grease to the parts which have
been under water for a long time until the used grease is pro-
jected. (Around the bucket pin, in particular)

If the hybrid devices (motor-generator, electric swing mo-
tor, inverter, and capacitor) or high-voltage electrical wir-
ing get in the water, the hybrid system not only stops but
also serious personal injury or death may be caused.
If someone touches the hybrid devices or high-voltage
electrical wiring by mistake, it is dangerous that causes an
electric shock. Always ask your Komatsu distributor for
the inspection and repair.
