. OPERATION WORKSITE to the cables can cause electric shock, so always maintain a safe distance from the cables. To prepare for any possible emergencies, wear rubber shoes and gloves. Lay a rubber sheet on top of the seat, and be careful not to touch the chassis with any exposed part of your body. Use a signalman to give warning if the machine approaches too close to the electric cables. When performing operations near high voltage cables, do not let anyone near the machine. If the machine should come too close or touch the electric cable, to prevent electric shock, the operator should not leave the operator's compartment until it has been confirmed that the electricity has been shut off.
Also, do not let anyone come close to the machine. Voltage of Cables Safety Distance 100V - 200V Over 2 m (7 ft) 6600V Over 2 m (7 ft) 22000V Over 3 m (10 ft) 66000V Over 4 m (14 ft) 154000V Over 5 m (17 ft) 187000V Over 6 m (20 ft) 275000V Over 7 m (23 ft) 500000V Over 11 m (36 ft) ENSURE GOOD VISIBILITY If the machine travels or carries out operations in places where the visibility is poor, always do as follows. If it is impossible to ensure good visibility, position a signalman where necessary. The operator should pay careful attention to signs and follow the instructions of the signalman. Only one signalman should give signals.
When working in dark places, turn on the working lamp and front lamps installed to the machine, and set up additinal lighting in the work area if necessary. Stop operation if the visibility is poor, such as in mist, snow, rain, or dust. CONFIRMATION OF MARK On soft road shoulders or ground surfaces, set up signs to make the condition of the ground clear. In addition, make sure that all operators fully understand the meaning of all the signs. 3 - 129 DO NOT GO CLOSE TO HIGH-VOLTAGE CABLE Do not travel or carry out operations near electric cables. There is danger of suffering elect ric shock.
Always do as follows on worksites where there is danger of the machine coming into contact with electri c cables. Before starting work near electric cables, inform the local power company of the work to be performed, and ask them to take the necessary action.
