It is da ngerous if the engine stops when the machine is traveling, because the stop the machine. steering becomes heavy. If the engine s tops, depress the brake p edal immediately to etting the dump lever at FLOAT position, then travel. Lower the dump body, s etting the dump lever at FLOAT position, To prevent the machine from rolling over when traveling on rough ground, travel at low spee d and avoid sudden changes in direction. ing out operations, always keep a safe distance from people, structures, or other ng into contact with them.
When traveling or carry machines to avoid comi When passing over brid ges or structures, check first that the struc ture is strong enough to su pport the weight of the machine. When operating in tunne ls, inside buildings, or under bridges or el ectric wires, or other place s where the height is limited, operate slowly and be extremely careful not to let the m achine or dump body cont act anything. Continuous long time tr aveling at high speed may cause tires to heat up, abnormally incr easing the inflation pressure inside the tires, injury or death. and to blow up.
The explosion of the tire is very destructive, and it can lead to serious tsu distributor before doing long continuous traveling.
