WARNING: For reasons of safety, always follow these safety precautions. SAFETY Never turn the key to the OFF position in the starting switch when traveling. It is dangerous if the engine stops when the machine is traveling, because the steering becomes heavy. If the engine stops, apply the brake immediately to stop the machine. It is dangerous to look around excessively when operating. Concentrate on your work. It is dangerous to drive too fast, or to start suddenly, stop suddenly, turn sharply or zig zag.
If you find any abnormality in the machine during operation (noise, vibration, smell, incorrect gauge readings, air leakage, oil leakage, etc.) move the machine immediately to a safe place and investigate the cause of the problem. Set the work equipment to a height of 40-50 cm (16-20 in) from the ground level and travel on level 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. Do not operate the steering wheel suddenly. 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 traveling on rough ground, travel at low speed, and avoid sudden changes in direction. Avoid traveling over obstacles. IF the machine has to travel over an obstacle, keep the work equipment as close tot he ground as possible, and travel at low speed. When traveling or carrying out operations, always keep your distance from other machines or structures to avoid collisions. NEVER enter water in excess of the permissible water depth. Permissible water depth PRECAUTIONS FOR OPERATION” on page 2-69. When passing over bridges or structures on private land, check first that the structure is strong enough to support the mass of the machine.
When traveling on public roads, check first with the relevant authorities and follow their instructions. Always obey the traffic regulations when traveling in public roads. This machine travels at a lower speed than automobiles, so keep to the side of the road and be careful to leave the center of the road free for other vehicles. The tires can overheat and develop excess pressure if subjected to sustained high-speed use, for which they were not designed. Tires then may fail, causing loss of control. If you must travel continuously consult Komatsu America International, or your distributor. WA450-3MC 1-12 PRECAUTIONS WHEN TRAVELING
