WHEN TRAVELING
Serious personal injury or death can result from tipping over of the traveling machine or its accidental contact.
Always observe the following.
• Never turn the key in the starting switch to OFF position when the machine is traveling. If the engine stops
when the machine is traveling, the steering wheel becomes heavy to operate, and this will cause a wrong
operation of the steering wheel and may lead to serious personal injury or death. If the engine stops, de-
press the brake pedal immediately to stop the machine.
• When driving the machine or performing operations, always keep a safe distance from people, structures,
or other machines to avoid coming into contact with them.
• Try to avoid traveling over obstacles. If that is unavoidable, let the machine do that at a low speed. The
machine tips over easily to the right or left. Do not drive it over obstacles which make the machine tilt large-
ly to the right or left.
• When traveling on rough ground, drive the machine at low speed and avoid sudden changes in direction to
prevent the machine from turning over.
• Do not load the dump body above the maximum payload. The brakes will lose their effect.
• Lower the dump body, setting the dump lever at “FLOAT” position, then drive the machine.
• When passing over bridges or structures, check first that the structure is strong enough to support the
weight of the machine.
• When operating in tunnels, under bridges, under electric wires, or other places where the height is limited,
operate slowly and be extremely careful not to let the machine body or work equipment hit anything.
• 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 1 position while traveling.
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 1 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.
