SAFETY

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.
If the engine cannot be started again after it has stopped, immediately operate the work equipment control levers
to lower the work equipment to the ground. (After the engine stops, the accumulator allows the work equipment
to be operated for a limited time.)
Be careful not to approach too close to the edge of cliffs. When making embankments or landfills, or when
dropping soil over a cliff, dump one pile, then use the next pile of soil to push the first pile.
The load suddenly becomes lighter when the soil is pushed over a cliff or when the machine reaches the top of
a slope. When this happens, there is danger that the travel speed will suddenly increase, so be sure to reduce
the speed.
When the bucket is fully loaded, never start, turn, or stop the
machine suddenly. There is danger of the machine turning over.
When handling unstable loads, such as round or cylindrical
objects, or piled sheets, if the work equipment is raised high,
there is danger that the load may fall on top of the operator'
compartment and cause serious injury or death.
When handling unstable loads, be careful not to raise the work
equipment too high or tip the bucket back too much.
If the work equipment is suddenly lowered or suddenly stopped,
the reaction may cause the machine to tip over. Particularly
when carrying a load, be sure to operate the work equipment
carefully.
When operating in tunnels, under bridges, under electric wires,
or other places where the height is limited, be extremely careful
not to let the machine body or work equipment hit 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.
