Prohibited Operations SAFETY If the machine rolls over or falls, or the ground at the working point collapses, it may lead to serious personal injury or death. Always observe the following precautions: Do not excavate the work face under an overhang. There is danger that the work face will collapse. When digging, never thrust the bucket into a load at an angle. This will bring an excessive load to bear on the machine and will reduce the service life of the machine. It is dangerous to apply drive force when excavating a rock face. In addition, an excessive load will be brought to bear on the machine and damage the machine. Never carry out digging operations on a downhill slope.
An excessive load will be brought to bear on the machine and damage the machine. Do not use the bucket or lift arm for crane operations. There is danger that the machine will tip over and that the load will fall. Do not pass the bucket over the head of other workers or over the operator’s seat of dump trucks or other hauling equipment. The load may spill or the bucket may hit the dump truck and cause serious personal injury or death.
Avoiding Dangerous Situations When using the machine, to prevent personal injury caused by damage to the work equipment or by the machine overturning due to overloading, do not exceed the permitted performance of the machine or the maximum permitted load for the structure of the machine. If the engine cannot be started again after it has stopped, immediately operate the work equipment control levers to lower the work equipment to the ground. (After the engine stops, the accumulator allows the work equipment to be operated for a limited time.) Be careful not to approach too close to the edge of cliffs.
When making embankments or landfills, or when dropping soil over a cliff, dump one pile, then use the next pile of soil to push the first pile. The load suddenly becomes lighter when the soil is pushed over a cliff or when the machine reaches the top of a slope. When this happens, there is danger that the travel speed will suddenly increase. Be sure to reduce the speed. Avoid traveling with the bucket raised. Raising the bucket raises the center of gravity on the machine. Traveling with a raised bucket, especially a loaded bucket, may result in loss of control or a rollover situation. Never raise the bucket unless the machine is stopped. WA430-6 1-31
