To avoid hitting the work equipment, always do the following; When working in tunnels, on bridges, under electric wires, or when parking the machine or carrying out other operations in places with limited height, be extremely careful not to hit the bucket or other parts. To prevent collisions, operate the machine at a safe speed when working in confined spaces, indoors, or in crowded areas. Do not pass the bucket over the heads of workers or over the operator's compartment of dump truck. AVOID HIGH-VOLTAGE CABLES Serious injury or death can result from contact or proximity to high-voltage electric lines.
The bucket does not have to make physical contact with power lines for current to be transmitted. Use a spotter and hand signals to stay away from power lines not clearly visible to the operator. HAOA230L Figure 25 Use these minimum distances as a guideline only. Depending upon the voltage in the line and atmospheric conditions, strong current shocks can occur with the boom or bucket as far away as 4 - 6 m (13 - 20 ft) from the power line. Very high voltage and rainy weather could further decrease that safety margin. NOTE:
Before starting any type of operation near power lines (either above ground or buried cable-type), you should always contact the power utility directly and work out a safety plan with them. OPERATE CAREFULLY ON SNOW, ICE AND IN VERY COLD TEMPERATURES In icy cold weather avoid sudden travel movements and stay away from even slight slopes. The machine could skid off to one side very easily. Snow accumulation could hide or obscure potential hazards. Use care while operating or while using the machine to clear snow. Warming up the engine for a short period may be necessary, to avoid operating with sluggish or reduced working capacity.
The jolting shocks and impact loads caused by bumping or bottoming the boom or attachment are more likely to cause severe stress in very cold temperatures. Reducing work cycle rate and work load may be necessary. When the temperature rises, frozen road surfaces become soft, so the machine travel becomes unstable. In cold weather, do not touch metal surfaces with your bare hands. If you touch a metal surface in extremely cold weather, your skin may freeze to the metal surface. 022-00058E Operation and Maintenance Manual Safety 1-27 Voltage Minimum Safe Distance 6.6 kV 3 m (9' 10") 33.0 kV 4 m (13' 1") 66.0 kV 5 m (16' 5") 154.0 kV 8 m (26' 3") 275.0 kV 10 m (32' 10")
