PRECAUTIONS FOR OPERATION
PRECAUTIONS WHEN TRAVELING
q 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. If the engine stops, depress the brake pedal
immediately to stop the machine.
q When traveling on level ground, keep the work equipment
at height of 40 to 50 cm (16 to 20 in) from the ground.
When traveling, do not operate the work equipment control
levers. If the work equipment control levers have to be
operated, stop the machine first, then operate the levers.
q 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 bal-
ance, 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 work equip-
ment hit anything.
q Always obey the traffic regulations when traveling on public
roads. This machine travels at a lower speed than normal
automobiles, so keep to the side of the road and be careful
to leave the center of the road free for other vehicles.
q 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 an extremely large
destructive force, and this may cause serious injury or acci-
dent.
If you are going to travel continuously, please consult your
Komatsu distributor.
