PRECAUTIONS FOR OPERATION

PRECAUTIONS WHEN TRAVELING

When traveling or carrying out operations, always keep a safe distance from people, structures, or other
machines to avoid coming into contact with them.
When traveling on the level ground, keep the work equipment
approximately 40 to 50 cm above the ground. Otherwise, the
work equipment may contact to the ground and the machine
may be turned over.
If the view to the right side is poor, raise the boom to ensure
better visibility.
For machines equipped with an auto-deceleration system,
always turn the auto-deceleration switch OFF when traveling on
rough ground or steep slopes. If the machine is operated with
the auto-deceleration system ON, the engine speed will rise and
the machine travel speed may suddenly become faster.
Avoid traveling over obstacles when possible. If the machine
has to travel over an obstacle, keep the work equipment close
to the ground and travel at low speed. There is more danger of
the machine tipping over to the left or right than tipping over to
the front or rear, so do not travel over obstacles which make the
machine tilt strongly to the left or right sides.
When traveling on rough ground, travel at low speed and do not
operate the steering suddenly. There is danger that the machine
may turn over. The work equipment may hit the ground surface
and cause the machine to lose its balance, or may damage the
machine or structures in the area.
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 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.
