SAFETY
PRECAUTIONS FOR OPERATION
PRECAUTIONS WHEN TRAVELING
Never turn the key in the starting switch to the OFF position. It is dangerous if the engine stops when the machine
is traveling, because the steering becomes heavy. There is danger that this will cause misoperation of the
steering wheel and may lead to serious personal injury or death. If the engine stops, depress the brake pedal
immediately to stop the machine.
When traveling or carrying out operations, always keep a safe distance from people, structures, or other
machines to avoid coming into contact with them.
Try to avoid having the machine climb over obstacles. If that is unavoidable, let the machine do that at a low
speed. Nonetheless avoid a big obstacle that greatly tilts the machine to the right or left, because in such a case
the machine can easily overturn sideways.
When traveling on rough ground, travel 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 travel.
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 travel continuously, please consult your Komatsu distributor.
When travelling, and particularly when travelling downhill, never set the gear shift lever to the Neutral position.
Always keep it in a speed range when travelling.
If the gear shift lever is at Neutral, it will be impossible to use the braking force of the engine and the steering
will become heavier. In addition, there will be insufficient cooling oil for the retarder, so there is danger that this
will result in overheating, which will lead to defective operation of the brakes.
The transmission and other parts of the power train may be damaged, and there is danger that this will lead
to serious injury or death.
TRAVELING ON SLOPES
To prevent the machine from tipping over or slipping to the side, always do as follows.
When traveling downhill, use the retarder brake to reduce speed. Do not turn the steering wheel suddenly.
Travel on grass, fallen leaves, or wet steel plates with low speed. Even with slight slopes there is a hazard that
the machine may slip.
If the engine should stop on a slope, apply the brakes fully and apply the parking brake also to stop the machine.
Do not shift gear while traveling downhill or travel downhill with the transmission in neutral.
It is dangerous if the engine has no braking effect. Always set the transmission to a lower gear before starting
to travel downhill.
PRECAUTIONS WHEN OPERATING
When using the machine, to prevent personal injury caused by damage to the work equipment or by the machine
overturning due to overloading, do not exceed the permitted performance of the machine or the maximum
permitted load for the structure of the machine.
When operating in tunnels, or under bridges or 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, particular in confined spaces, indoors, and in places where there are other machines.
