SAFETY STANDARDS WHEN RUNNING 2
q
It is dangerous to drive too fast, or to start suddenly, stop suddenly, or to turn sharply.
q
When traveling on flat ground, keep the work equipment 40
to 50 cm (16 to 20 in) high above the ground.
q
Move at low speed and do not turn the steering wheel
abruptly when moving over rough terrain. There is a hazard
that the machine may become unstable and tip 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.
q
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.
Never travel over obstacles which make the machine tilt
strongly to one side.
q
When traveling or carrying out operations, always keep a
safe distance from people, structures, or other machines to
avoid coming into contact with them.
q
When passing over bridges or structures, check first that
the structure is strong enough to support the weight of the
machine. When traveling on public roads, check first with
the relevant authorities and follow their instructions.
q
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.
q
For machines with the canopy specification, when the work equipment is operated to the maximum left boom
swing with the work equipment in the minimum swing posture, soil may spill from the bucket and fall on to the
floor. Be extremely careful when operating in this posture.
