Always maintain the safe distance given below between the machine and the electric cable. The following actions are effective in preventing accidents. 1) Wear shoes with rubber or leather soles. 2) Use a signalman to give warning if the machine approaches too close to the electric cable. If the work equipment should touch the electric cable, the operator should not leave the operator’s compartment. When carrying out operations near high voltage cables, do not let anyone come close to the machine.
Check with the electricity company about the voltage of the cables before starting operations.

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. Be careful not to let the bucket hit the dump truck or the side of the excavated ditch. 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, so be sure to reduce the speed. Always carry out loading operations up-wind to protect yourself from dust. When the bucket is fully loaded, be particularly sure to avoid sudden starting, turning, or stopping. When loading a dump truck, check that there is no one in the area. Be careful also that the load does not drop when it is being loaded. -j ENSURE GOOD VISIBILlTY 1 l When working in dark places, install working lamps and head lamps, and set up lighting in the work area if necessary.
l Stop operations if the visibility is poor, such as in mist, snow, or rain, and wait for the weather to improve to a condition that allows the operation to be carried out safely. 1-11
