• If you drive the machine at high speed continuously for a long time, the tires will overheat and the internal
pressure will become abnormally high. This may cause the tires to burst. If a tire bursts, it produces a large
destructive force, and this may cause serious injury or death.
If you are going to drive the machine continuously, consult your Komatsu distributor.
• When traveling, and particularly when traveling downhill, never set the gear shift lever to NEUTRAL position
(N). If the gear shift lever is set to NEUTRAL position (N) while driving the machine at travel speed of above
4 km/h or traveling downhill, the gear speed is not changed to neutral. The centralized warning lamp flashes
and the alarm buzzer sounds. Always set the gear shift lever in D to L position while traveling.
PRECAUTIONS WHEN TRAVELING ON SLOPES
To prevent the machine from tipping over or slipping to the side, always observe the following.
• When traveling downhill, use the retarder brake to reduce speed. Do not turn the steering wheel suddenly.
• Do not work on a slope covered with the steel plates. Even with slight slopes there is a hazard that the
machine may slip.
• Drive the machine at low speed on the grass or fallen leaves. Even with slight slopes, there is a hazard that
the machine may slip.
• If the engine should stop on a slope, immediately apply the brakes fully and apply the parking brake also to
stopping the machine.
• When traveling downhill, do not drive the machine with the gear shift lever in NEUTRAL position (N).
If the gear shift lever is set to NEUTRAL position (N) while driving the machine at travel speed of above
4 km/h or traveling downhill, the gear speed is not changed to neutral. The centralized warning lamp flashes
and the alarm buzzer sounds. Always set the gear shift lever in D to L position while traveling.
PRECAUTIONS WHEN OPERATING MACHINE
• When using the machine, to prevent serious personal injury or death caused by the work equipment or by
the machine tipping over due to overloading, do not use the machine beyond the permitted performance of
the machine such as the maximum permitted load for the structure of the machine.
• When operating in tunnels, or under bridges or under electric wires, or in other places where the height is
limited, operate slowly and be extremely careful not to let the dump body contact anything.
• To prevent accidents caused by hitting other objects, always operate the machine at a speed which is safe
for operation, particularly in confined spaces, indoors, and in places where there are other machines.
WHEN LOADING ON DUMP BODY
• Do not load the dump body so that the load is on one side. Always perform loading that the load is spread
uniformly.
• Do not leave or return to the operator's seat while the dump body is being loaded.
WHEN DUMPING
• Before starting the dumping operation, check to be sure there is no people or object behind the machine.
• Stop the machine in a right position, and check again that there is no people or object behind the machine.
Give the determined signal, then slowly operate the dump body. If necessary, use chocks for the wheels or
allocate a conductor.
• Do not perform dumping operations on slopes. The machine stability will become poor and it may tip over.
• Do not drive the machine with the dump body raised.
• When the dump body is raised, the center of gravity of the machine varies continuously. If the ground is
soft, this will affect the stability of the machine.
• Take extreme care when dumping sticky material (wet clay, frozen material, etc.) on a soft ground. The sta-
bility of the machine becomes worse and it may tip over.
WHEN OPERATING ON SNOW OR FROZEN SURFACES
• Snow-covered or frozen surfaces are slippery, so be extremely careful when traveling or operating the ma-
chine, and do not perform abrupt lever operation. Machine may slip even on a slight slope. Be particularly
careful when working on slopes.
