OM2044 Safety - Section 20 Page 20-7 Ensuring Good Visibility When working in dark places, install work lamps and head lamps. Driving Near High Voltage Cables Driving near high-voltage cables can cause electric shock. Always maintain the safe distances between the machine and the electric cable as listed below. Discontinue operations if visibility is poor, such as in mist, snow, or rain. Wait for the weather to improve to allow the operation to be performed safely. Operating On Snow When working on snowy or icy roads, there is danger that the machine may slip to the side on even the slightest slope. Always travel slowly and avoid sudden starting, turning, or stopping in these conditions.
Be extremely careful when clearing snow. The road shoulder and other objects are buried in the snow and cannot be seen. When traveling on snow-covered roads, always install tire chains. The following actions are effective in preventing acci- dents while working near high voltages: Wear shoes with rubber or leather soles. Use a signalman to give warning if the machine approaches an electric cable. Avoid Damage To The Dump Body When working in tunnels, on bridges, under electric cables, or when entering an enclosed area where there are height limits, always use extreme caution. The dump body must be completely lowered before driving.
If the work equipment touches an electric cable, the operator must not leave the cab. When performing operations near high voltage cables, DO NOT allow anyone to approach the machine. Check with the electrical maintenance department about the voltage of the cables before starting operations. Driving with a raised dump body or raising the dump body in an enclosed area, may result in serious damage and bodily injury or death. Always drive with the dump body resting on the frame. When Loading The Truck Ensure the surrounding area is safe. If so, stop the machine in the correct loading position and evenly load the body. DO NOT leave the operator's seat during the loading operation.
When Dumping Before dumping, check that there is no person or objects behind the machine. Stop the machine in the desired location. Check again for persons or objects behind the machine. Give the determined signal, then slowly operate the dump body. If necessary, use blocks for the wheels or position a flagman. When dumping on slopes, machine stability is poor and there is danger of tip over. Always perform such operations using extreme care. Never travel with the dump body raised.
