Safety 2.3 Precautions for operation z If there is an area to the rear of the machine which cannot be seen, position a signal person. Take special care not to hit other machines or people when turning or swinging the machine. Always be sure to carry out the above precautions even when the machine is equipped with mirrors. Precautions when traveling GK032053 z Never turn the key in the starting switch to the OFF position. It is dangerous if the engine stops when the machine is trav- eling, because the steering becomes heavy. If the engine stops, depress the brake pedal immediately to stop the machine.
z When traveling on level ground, keep the work equipment at height of 270 mm (10 to 11 in) from the ground. z When traveling, do not operate the work equipment control levers. If the work equipment control levers have to be oper- ated, stop the machine first, then operate the levers. z 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. 270 mm GK032054 z 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. z When traveling or carrying out operations, always keep a safe distance from people, structures, or other machines to avoid coming into contact with them. z 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.
z 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. z 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. z 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 destruc- tive force, and this may cause serious injury or accident. z If you are going to travel continuously, please consult your KOMATSU distributor. WA150-5H – VEAM934100 2-19
